Metabolic dysfunction-associated steatotic liver disease (MASLD) is a global health concern, even among lean individuals. The Gan-Jiang-Ling-Zhu decoction (GZD), a traditional Chinese medicine formula, shows therapeutic potential against MASLD. This study investigated the efficacy of GZD in lean MASLD and explored its mechanisms of action.

A lean MASLD mouse model was established using C57BL/6 mice fed with a cholesterol-rich Paigen’s diet (PD). Following successful modeling, mice were administered GZD (1.8, 3.6, or 7.2 g/kg) or vehicle control. Body weight, food intake, and liver weight were monitored. Hepatic steatosis and lipid accumulation were assessed via H&E and Oil Red O staining, while serum enzymes were quantified biochemically. Gut microbiota composition was analyzed by 16S rRNA gene sequencing, and bile acid (BA) profiles in feces and serum were measured using UPLC-TQMS.

Twelve weeks of PD feeding induced a lean MASLD phenotype characterized by reduced body weight alongside hepatic steatosis and dyslipidemia. The GZD treatment dose-dependently ameliorated liver steatosis and lipid accumulation, with the highest dose (7.2 g/kg) showing superior efficacy. GZD restored gut microbiota balance by reducing pathogenic bacteria and enriching taxa involved in BA metabolism, leading to increased fecal excretion of secondary BAs. Conversely, serum levels of secondary BAs were significantly reduced after GZD treatment.

Our study highlights the promising role of GZD in lean MASLD, the involvement of gut microbiota and related BA metabolism that aligns with emerging evidence that gut dysbiosis and disrupted BA homeostasis are central to MASLD pathogenesis, even in lean individuals. However, the mechanistic links between specific microbial changes, BA pool composition, and hepatic outcomes remain to be elucidated.

GZD ameliorates hepatic steatosis in lean MASLD mice, an effect associated with modulation of gut microbiota composition and increased fecal excretion of secondary BAs. These findings suggest the potential of GZD as a therapeutic option for lean MASLD through gut-liver axis regulation.

Bladder cancer (BLCA) is a highly aggressive malignancy with poor prognosis. DNA replication stress-related genes (DRSGs) hold prognostic significance in multiple cancers, and their expression patterns in BLCA may reveal novel biomarkers and therapeutic targets.

This study was designed using a public database and the Cancer Genome Atlas (TCGA). Genes associated with DNA replication stress in BLCA were discovered by analyzing data from the TCGA and GEO databases using bioinformatics tools. The prognostic gene expression profiles in BLCA cell lines were analyzed using Western blotting (WB). The motility capacity of BLCA cells was evaluated using the wound healing and Transwell migration assays, while cell growth was ascertained with the CCK-8 assay.

Five DRSGs with prognostic significance were identified, and a risk score model was constructed using univariate Cox regression and the Least Absolute Shrinkage and Selection Operator (LASSO) regression algorithm. Kaplan-Meier (KM) analysis showed worse Overall Survival (OS) in the high-risk group (P < 0.05). Gene Set Enrichment Analysis (GSEA) indicated involvement in tumor-related pathways. The nomogram effectively predicted OS in both training and validation cohorts. WB and functional assays confirmed gene expression and effects on BLCA cell proliferation and migration.

This study first validates DRSGs’ prognostic value in bladder cancer, highlighting potential biomarkers and targets. Limitations include reliance on public data and in vitro tests. Future research should use multicenter cohorts and animal models to confirm clinical relevance.

Chronic atrophic gastritis (CAG) is the initial phase in the carcinogenesis of gastric cancer (GC). Therefore, effective treatment for CAG is important in reducing the risk of GC progression. As an isoflavone compound, formononetin (FMN) has been identified as a potential therapeutic agent for acute gastric ulcers and GC. However, no study has reported the protective effect of FMN against CAG and its underlying mechanism. This study aimed to explore the therapeutic effects of FMN on CAG and its underlying mechanisms in vitro.

Network pharmacology was applied to predict the core targets of FMN therapy in CAG. The CAG cell model was developed using N-methyl-N-nitro-N-nitrosoguanidine (MNNG)-triggered human gastric epithelial cells (GES-1). The CCK-8 assay was applied to estimate cellular viability. The expression of inflammatory cytokines in cell supernatant was detected by ELISA. The protein levels and localization of nuclear receptor coactivator 1 (NCOA1), c-Jun, and c-Fos were evaluated using western blotting and immunofluorescence staining. Cell apoptosis was measured using flow cytometry.

Network pharmacology analysis identified c-Jun as the core target of FMN in the treatment of CAG, with biological processes primarily involving the regulation of apoptosis and inflammation. In vitro, MNNG exposure reduced GES-1 cell viability as well as increased inflammation and cellular apoptosis, and these effects were reversed by FMN treatment. In detail, FMN decreased the protein levels of NCOA1, c-Jun, and c-Fos in MNNG-triggered GES-1 cells. The activator protein-1 (AP-1) inhibitor T-5224 enhanced the effects of FMN treatment on cell viability, inflammatory response, and apoptosis in MNNG-triggered GES-1 cells.

This study employed network pharmacology analysis to identify FMN's therapeutic targets for CAG and validated the underlying mechanisms in vitro. While these results are promising, in vivo validation is required to confirm the efficacy of FMN. A comparative pharmacological evaluation against existing therapeutic agents and bioactive compounds would further elucidate FMN's therapeutic potential for CAG treatment.

FMN ameliorated the cell damage that MNNG triggered in GES-1 cells. The mechanism involved the anti-inflammatory and anti-apoptotic effects of FMN via modulation of the NCOA1/AP-1 signaling axis. The present preliminary study found FMN to exhibit a potential therapeutic effect against CAG.

Individual constitutions are classified into nine types in traditional Chinese medicine (TCM), and qi stagnation constitution (QSC) manifests as disrupted Qi circulation and increased susceptibility to emotional disorders and cancers. However, as a pre-disease state mainly affecting women, the biological basis of QSC and its susceptible mechanism to related diseases are still unclear. Exosomal microRNAs (miRNAs) are the stable regulators of gene expression and intercellular communication, and analysis of miRNAs enables us to understand the QSC better. This study profiles plasma exosomal miRNAs in QSC and balanced constitution (BC) females via high-throughput sequencing, aiming to identify the potential biomarkers of QSC and reveal its biological basis and the mechanism of its susceptible disease.

In this cross-sectional observation, female college students were recruited according to the criterion of QSC and BC in Classification and Determination of Constitution in TCM. Exosomal miRNAs were isolated from peripheral blood plasma and then profiled using high-throughput sequencing. Differentially expressed miRNAs (DEMs) were identified with fold change > 2 and P < 0.05, and screened as biomarkers to construct the receiver operating characteristic (ROC) curve. The diagnostic values of these biomarkers in different types of cancers were also validated based on the published data. Functional analysis were explored based on the predicted target genes.

Subjects with QSC showed significantly higher concentrations of albumin (ALB) and alkaline phosphatase (ALP) compared to those with BC, while there was no significant difference in baseline information and other clinical indicators between groups. A total of 54 DEMs were identified, including 30 up-regulated and 24 down-regulated miRNAs in the QSC group. The area under the ROC curve (AUC) for 7 specific up-regulated DEMs was 1.0, as well as the AUCs for therein 6 DEMs in various cancers were all above 0.9. The enriched KEGG (Kyoto Encyclopedia of Genes and Genomes) pathways included “signal transduction,” “infectious disease,” and “cancers”, and the most associating systems included immune, endocrine, and nervous systems, while the GO (Gene Ontology) function was mainly enriched in “protein binding,” “nucleus” and “transcription, DNA-templated”.

These 7 potential biomarkers of QSC have been confirmed to regulate oncogenic processes through epithelial-mesenchymal transition modulation and metabolic reprogramming, as well as therein 1 can also improve depression by lowering the expression of 5-hydroxytryptamine 1A receptor. The results of this study deepen the understanding of the constitutions in TCM. However, the small single-sex sample limits the application of the conclusion, and a large-scale clinical cohort including both sexes is still needed in future.

The expression of exosomal miRNAs in QSC showed unique features that have the potential to serve as biomarkers, and the related functional changes might be the biological basis for the susceptible diseases of QSC.

Depression is a common comorbidity in epilepsy, significantly impacting patients' quality of life. The hippocampus, linked to depression and neurodegeneration, is vulnerable in epilepsy. Epileptogenesis involves inflammation, oxidative stress, and neuronal damage, with the PI3K/AKT pathway playing a key role. Apigenin (API), a flavonoid in fruits and vegetables, shows neuroprotective, anti-inflammatory, and anti-apoptotic effects. This study investigates API's mechanisms in a LiCl-pilocarpine epileptic rat model, focusing on hippocampal neurogenesis and PI3K/AKT signaling as potential therapeutic targets.

We studied the effects of API and valproate (VPA) on depressive behavior and astrocytes in Lithium chloride (LiCl)-pilocarpine-induced epileptic rats. Additionally, we predicted the potential molecular targets of API for treating epilepsy using network pharmacology. Finally, we conducted in vivo experiments to validate the predicted mechanism.

In the API and VPA groups, there was a reduction in seizure frequency and seizure severity compared with the control group. The model group showed more depressive behavior than the control (CON) group, and these behaviors improved significantly after VPA and API treatment. HE staining showed that both API and VPA treatment improved LiCl-pilocarpine-induced nuclear contraction and cell swelling. Nissl staining demonstrated that Nissl vesicles in the CA3 region of the hippocampus were decreased in the model group, but the neurons were larger, more abundant, and more neatly arranged after API and VPA treatment. In the model group, the p-PI3K/PI3K and p-AKT/AKT protein ratios and PI3K, AKT mRNA expression were reduced, while brain-derived neurotrophic factor (BDNF) and glial fibrillary acidic protein (GFAP) were markedly increased. API and VPA treatment effectively reversed these changes.

API reduces seizures and depressive behaviors in LiCl-pilocarpine-induced epileptic rats, comparable to VPA API mitigates hippocampal neuronal damage, preserves Nissl bodies, and suppresses astrocyte activation via the PI3K/AKT pathway, suggesting neuroprotective and anti-inflammatory effects. While API shows promise as an antiepileptic and antidepressant agent, further studies are needed to confirm its direct modulation of PI3K/AKT and efficacy in other epilepsy models.

Our study suggests that API improves depression in rats and has anti-epilepsy activity, which may be involved in activating the PI3K/AKT pathway to protect astrocytes.

To develop and characterize a Crocus sativus (saffron)-based solid lipid nanoparticle (SLN) nasal spray for treating depression by enabling direct nose-to-brain delivery and evaluating its antidepressant potential in a Drosophila melanogaster model.

Phytochemical screening, antioxidant assays, and HPLC quantification of picrocrocin were performed on Crocus sativus extract. The SLN-based nasal spray was formulated and characterized for particle size, zeta potential, polydispersity index (PDI), drug entrapment efficiency, in vitro drug release, and stability over 4 weeks. The antidepressant efficacy was assessed via a climbing assay in Drosophila melanogaster.

Phytochemical analysis revealed phenolic content (11–36 μg GAE/mg), flavonoid content (43–56 μg QE/mg), and carotenoid content (1.9–30 μg βC/mg). HPLC analysis quantified picrocrocin at 6.3 mg/g, confirming its presence. The SLNs exhibited a particle size of 110–225 nm, a zeta potential of -1 to -0.8 mV, a PDI of 1, and a drug entrapment efficiency of 99.76%. Drug release reached 37% over 270 minutes, and the nasal spray maintained a pH of 5.8, a viscosity of 23.1 cP, and stability over 4 weeks. In vivo, the climbing assay demonstrated improved locomotor activity, indicating significant antidepressant potential.

The favorable physicochemical characteristics of the nasal spray, along with the observed behavioral improvements in the fly model, suggest that Crocus sativus SLNs effectively cross the nasal-brain barrier and exert antidepressant-like effects. These findings support its potential for non-invasive management of treatment-resistant depression.

ARL6IP1 has been linked to cancer progression, but its precise role in BC, particularly in metabolism and its interaction with an OLFM4, remains unclear.

This study aimed to investigate the role of ADP-ribosylation factor-like 6 interacting protein 1 (ARL6IP1) in breast cancer (BC) cell behavior and metabolism and explore its interaction with an olfactomedin-4 (OLFM4) as a potential therapeutic target.

The objective of this study was to determine the effects of ARL6IP1 knockdown on BC cell proliferation, invasion, migration, apoptosis, oxidative stress, and glycolysis. Additionally, this study also explored the interaction between ARL6IP1 and OLFM4 and their combined role in BC progression and metabolism.

Key gene modules in the GSE73540 dataset were identified through weighted gene co-expression network analysis (WGCNA). Three BC-related datasets (GSE73540, GSE22820, and GSE36295) and The Cancer Genome Atlas (TCGA) were applied for additional examination of differentially expressed genes (DEGs). Intersection analysis selected ARL6IP1 as a hub gene for prognostic analysis. In vitro experiments investigated how ARL6IP1 knockdown influences BC cell proliferation, invasion, migration, apoptosis, epithelial-mesenchymal transition (EMT), oxidative stress, and glycolysis. The connection between ARL6IP1 and an OLFM4 was confirmed using Co-immunoprecipitation (Co-IP), and their roles in BC tumor progression and glycolysis were evaluated.

ARL6IP1 was elevated in BC datasets and linked with poor BC prognosis. Experiments demonstrated that knockdown of ARL6IP1 significantly reduced BC cell growth while promoting apoptosis and oxidative stress. Besides, ARL6IP1 knockdown reduced glycolysis, as manifested by decreased extracellular acidification rate (ECAR), glucose consumption, adenosine triphosphate (ATP) levels, and lactate production while increasing mitochondrial respiration (OCR). Co-IP validated the connection between ARL6IP1 and OLFM4, and OLFM4 overexpression partially counteracted the suppression of glycolysis and cell behavior resulting from ARL6IP1 knockdown.

ARL6IP1 is a critical regulator of BC progression, influencing glycolysis, mitochondrial function, and key cellular behaviors. Targeting the ARL6IP1-OLFM4 axis offers a promising therapeutic strategy for managing BC.

The objective of this study is to evaluate the role of mycoplasma resistance genes in pediatric mycoplasma pneumonia and to identify the factors that necessitate antibiotic adjustments.

We retrospectively analyzed clinical data from children diagnosed with mycoplasma pneumonia at Chongqing Medical University Children's Hospital (January-October 2023). We categorized patients based on antibiotic treatment adjustments: the antibiotic adjustment group and the no adjustment group. We compared demographic characteristics, clinical outcomes, and the gene resistance rate that point mutations A2063G and A2064G in the 23S rRNA between groups. Logistic regression was employed to determine the factors prompting a switch from macrolides to alternative antibiotics.

The study included 551 cases, with 341 in the no adjustment group and 210 in the antibiotic adjustment group (54 switched to doxycycline, 156 to levofloxacin). There was no significant difference in the prevalence of resistance genes between the groups (71.8% vs. 71.4%; P=0.916). Significant differences were observed in hospital stay duration, C-reactive protein (CRP), D-dimer, fibrinogen, procalcitonin levels, and lung consolidation (P<0.05). Logistic regression identified elevated CRP and procalcitonin levels as independent predictors of the need for alternative antibiotics.

Resistance genes do not predict the need for second-line antibiotics in pediatric mycoplasma pneumonia; however, elevated CRP, and procalcitonin levels significantly correlate with this necessity.

The mechanisms of chemotherapy sensitivity and toxicity are complex. Metabolomics can better reflect the status of anticancer drugs, tumors, and hosts simultaneously.

Mice were implanted with human gastric cancer cells through subcutaneous xenografting, and then treated with the PF (platinum-fluorouracil) regimen, with saline serving as the control. Tumor growth was monitored by measuring tumor volume, and body weight was recorded on Days 0, 2, 4, 6, and 8. Kidney damage was assessed using H&E staining. To analyze differential responses, PF-treated mice were grouped separately according to chemotherapy sensitivity (high/medium/low via tumor response) and toxicity (high/medium/low via body weight changes). Serum metabolomics was evaluated using Mass Spectrometry.

Platinum-Fluorouracil (PF) chemotherapy significantly reduced tumor weight in mice, although it also induced notable body weight loss and renal toxicity compared to controls. Serum metabolomic analysis revealed significant differences between PF and control groups, involving metabolites like deoxymethylmycin and dehydrocorticosterone, associated with AMPK and cortisol synthesis/secretion pathways. Further comparisons highlighted: (1) High- vs. low-sensitivity subgroups differed significantly in metabolites, such as palmitoyl-CoA and indoleacetic acid (linked to AGE-RAGE, insulin resistance, and AMPK pathways). (2) High- vs. low-toxicity subgroups displayed significant metabolic differences, including methylguanosine and methylcytidine (implicated in ferroptosis, ether lipid, and fatty acid metabolism pathways).

The PF regimen effectively inhibits the growth of subcutaneous tumors in nude mice, while causing varying levels of sensitivity and toxicity in tumor chemotherapy. These observed effects of sensitivity and toxicity are linked to underlying metabolic mechanisms.

Bladder cancer (BC) is one of the most common urological malignancies, ranking as the eleventh most common cause of cancer-related deaths worldwide. The lack of specific and sensitive prognostic biomarkers presents a significant challenge in the early diagnosis and treatment of BC.

This study utilizes the Gene Expression Omnibus (GEO) dataset GSE13507 and the Cancer Genome Atlas (TCGA) database to screen differentially expressed genes related to BC. By using Weighted Gene Co-expression Network Analysis (WGCNA), two modules associated with BC were investigated in GSE13507 and TCGA. Hub genes were identified through Protein-Protein Interaction (PPI) network analysis, and their functions were validated through multiple approaches, including Gene Expression Profiling Interactive Analysis (GEPIA), Western Blotting (WB) assay, Human Protein Atlas (HPA), Oncomine analysis, and quantitative Real-Time PCR (qRT-PCR) analysis. Additionally, miRNAs associated with hub gene expression were identified using various databases to predict the progression and prognosis of BC.

WGCNA and a differential gene expression analysis identified 171 common genes as target genes. Ten genes (MYH11, ACTA2, TPM2, ACTG2, CALD1, MYL9, TPM1, MYLK, SORBS1, and LMOD1) were identified using the PPI tool. The CALD1 and MYLK genes showed a significant prognostic value for overall survival and disease-free survival in patients with BC. CALD1 and MYLK expression levels were significantly lower in BC tissues than in normal tissues. Furthermore, miR-155 showed a significant positive correlation with MYLK.

This study established MYLK as a direct target gene of miR-155, functioning as an actionable survival-related gene correlated with BC development.

Extracts from Porphyra have been detected to have antioxidant activity and tyrosinase (TYR) inhibitory activity. However, bioactive peptides (BPs) released from Porphyra proteins (PPs) have not been comprehensively reported.

The aim of this study is to rapidly identify bifunctional peptides with antioxidant and TYR inhibitory activities from a large number of digested peptides from PPs.

In this study, a total of 3,288 proteins from six main species of Porphyra were collected, and the antioxidant potential (AP) was evaluated. Hydrolyzed peptides with 2–8 amino acid lengths were collected and known antioxidants were removed. Next, these peptides were further screened using ADMET analysis. Finally, the DPPH· scavenging potential (IC50) and TYR inhibition potential (TIP) of these peptides were further predicted by QSAR models and molecular docking based pharmacophore models, respectively.

The most released antioxidant peptides after digestion of all types of PPs were dipeptides with sequences EL, IR and AY. In addition, 44,689 short non-repeatable peptides were swirled in these hydrolysates, which have not yet been reported to have antioxidant activity. Next, 337 of these digested peptides were predicted to be absorbed without hepato-renal toxicity and had virtual metabolic scores > 0.01%. Finally, 138 peptides were predicted to have AP and TIP.

Porphyra is a kind of promising source rich in bifunctional peptides. Present study adopted an innovative method with some free scripts to rapid discovery of bifunctional peptides from a large number of unknown PPs.

The duration of response to immune checkpoint inhibitors (ICIs) varies because of tumor immune heterogeneity, and employing programmed death receptor ligand 1 (PD-L1) expression to evaluate the efficacy of anti-programmed cell death-1 (PD-1)/PD-L1 antibodies remains controversial.

A total of 138 advanced non-small cell lung cancer (NSCLC) patients were subdivided into 2 groups - 52 patients with a PD-L1 Expression≥50% and 86 patients with a PD-L1 Expression <50% - based on next-generation sequencing (NGS) to analyze multiple-dimensional data types, including tumor mutation burden (TMB), gene alterations, gene enrichment analysis, therapy response, and immune-related adverse events (irAEs).

High levels of PD-L1 expression were significantly associated with advanced age and TMB status. The PD-L1≥50% cohort presented mutations of KRAS, NOTCH1, and FAT, while the PD-L1<50% group exhibited mutations of EGFR, PTEN, or LATS1/2. Except for the ascertained DNA damage response regulation. Even though there was no significant difference between PD-L1≥50% and PD-L1<50% cohorts on therapy response, patients with a PD-L1 Expression≥50% elicited a high irAEs incidence rate and increased plasma interleukin 6 (IL-6) concentration.

This real-world retrospective study suggested that high expression of PD-L1 exhibited inappropriate activation of different pathways and collaborated with anti-cytokines and chemokines therapy may optimize clinical therapy efficacy.

Shenhuang Liuwei powder (SHLWP) is frequently used to treat diabetic ulcers (DUs), but its mechanism of action remains poorly understood. This study aimed to identify the active compounds and mechanisms by which SHLWP alleviates DUs.

The chemical components of SHLWP were analyzed using high-resolution mass spectrometry (HRMS). Network pharmacology based on HRMS data identified SHLWP-associated targets and signaling pathways. Its antibacterial activity was assessed using Kirby-Bauer disc diffusion and minimum inhibitory concentration (MIC) tests. Its in vivo pharmacological effects were evaluated in a streptozotocin-induced diabetic ulcer model in Sprague-Dawley (SD) rats.

Seventy-three components were identified in SHLWP, with key constituents including caffeic acid (13.11 ± 0.14 μg/g), ferulic acid (20.40 ± 0.24 μg/g), quercetin (8.49 ± 0.18 μg/g), luteolin (36.63 ± 0.19 μg/g), apigenin (82.14 ± 1.60 μg/g), and linoleic acid (507.59 ± 1.46 μg/g). SHLWP exhibited strong antibacterial activity against Staphylococcus aureus (MIC = 7.8125 μg/mL), Streptococcus pyogenes (MIC < 3.90625 μg/mL), and Streptococcus epidermidis (MIC < 3.90625 μg/mL). Network pharmacology revealed significant enrichment of the AGE/RAGE, HIF-1, and PI3K-Akt pathways, which was validated in vivo using qPCR, immunohistochemistry, and Western blot.

SHLWP alleviated streptozotocin-induced diabetic ulcers by inhibiting the AGE/RAGE pathway and promoting antibacterial activity and angiogenesis via the PI3K/Akt/eNOS/HIF-1α pathway, providing a biological basis for its therapeutic effects.

The specific role of necroptosis in the pathogenesis of cataracts remains unclear. This study aimed to identify and validate the genes related to necroptosis in the development of cataracts through bioinformatics analysis.

We utilized RNA sequencing data (GSE161701) from the Gene Expression Omnibus (GEO) database and employed R software to perform differential expression analysis of necroptosis-related genes (NRGs) in lens epithelial cells (LECs) under oxidative stress. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were conducted to evaluate the functions of necroptosis-related differentially expressed genes (NRDEGs) and their associated pathways. Additionally, a diagnostic model was established using LASSO regression to select hub genes, and protein-protein interaction (PPI) networks, mRNA-miRNA, and mRNA-drug regulatory networks were constructed. Immune infiltration analysis was performed using the xCell and CIBERSORT algorithms, and the differential expression of hub genes was validated in a UVB-induced rat cataract model using RT-qPCR and immunohistochemistry.

The results indicated that oxidative stress promoted necroptosis in LECs, involving 86 NRDEGs and nine hub genes. GO and KEGG analyses revealed significant enrichment in necroptosis-associated pathways. Furthermore, we identified 58 mRNA-miRNA interactions and 131 potential molecular compounds or drugs. The immune infiltration analysis showed that certain immune cells exhibited significantly elevated expression in the cataract group, with notable correlations between some immune cells and hub genes. RT-qPCR and immunohistochemistry confirmed the expression of 9 hub genes and 3 key necroptosis genes. BAX, CXCL1, EPAS1, JUN, LRP1, RBM14, SERTAD1, and TNFAIP3 were highlighted as potential diagnostic and therapeutic targets.

This study identified key NRDEGs involved in the pathogenesis of cataracts under oxidative stress through bioinformatics analyses, potentially providing new targets and research directions for future cataract prevention and treatment.

Chenopodium album Linn. is a nutritionally and pharmacologically significant herb that generally grows in the winter season along with other crops. It is rich in fibers, protein, minerals (Mg, Ca, Fe, K, P, and others), vitamins (ascorbic acids, thiamine, riboflavin, and others), and several other biologically active chemical components like flavonoids, saponins, steroids and many more. In this article, the authors briefly describe and assess the chemistry and pharmacology of this nutritionally significant plant.

This study is based on several literature searches conducted via Google Scholar, Research Gate, PubMed, and many other online sources.

Due to its richness with bioactive phytochemicals, it has become a valuable functional food. C. album has several medicinal properties like antioxidant, antimicrobial, anti-arthritic, anti-diabetic, anti-infection, anti-ulcer, and many others. Even after its rich nutritional values, chemical compositions, and a broad spectrum of pharmacological properties, this is a highly ignored herb worldwide. Therefore, extensive research and awareness regarding the functional role of this herb is needed.

Diminished ovarian reserve (DOR) is accompanied by abnormal initiation and development of primordial follicles. Reporting that curcumin can protect the ovarian reserve, we used rats as a model to explore the regulatory mechanism of curcumin on primordial follicle priming.

Curcumin restores the ovarian microenvironment of DOR model rats by AMPK/SIRT 1 signaling pathway, thus regulating the initiation of primordial follicles.

The study used the ovaries of 3-day-old female rats, after replicating the DOR model by triptolide (TP), then used curcumin intervention for 3 days. Histomorphological analysis was counted by H & E staining; ELISA test was used to count ovarian hormone [follicle stimulating hormone (FSH) / luteinizing hormone (LH) ratio and estradiol (E2)] concentration in the culture supernatant. Spectrophotometric measurement was used to count of superoxide dismutase (SOD) and the malondialdehyde (MDA). The protein and mRNA expression of the pathway and key indicators for follicle initiation were determined by Western Blot and Q-PCR (AMPK, SIRT 1, PTEN, PGC-1 α, and AMH).

After curcumin treatment, the number of growing follicles increased (P < 0.05). FSH/LH ratio decreased but the content and expression of E2 and AMH increased (P < 0.05). The protein and mRNA expression of characteristic indicators of inhibiting primordial follicle initiation (PTEN) was decreased (P < 0.05). Oxidation-reduction-related SOD activity increased and the content of MDA decreased (P < 0.05), while the protein and mRNA expression of PGC-1α increased (P < 0.05). The protein and mRNA expression of the pathway (AMPK, SIRT 1) were increased (P < 0.05).

Curcumin restored the ovarian local oxidant-antioxidant balance and promoted primordial follicle priming through AMPK/SIRT 1 signaling pathway in the DOR model rats.

Astragaloside (AST), a natural saponin extracted from Astragalus membranaceus (Fisch.) Bunge., has been consistently utilized in the treatment of rheumatoid arthritis (RA). N6-methyladenosine (m6A), the most prevalent modification of mRNA, is associated with the progression of various diseases, including RA. Nonetheless, the effects of AST on m6A modification in RA remain to be elucidated.

The MH7A cell model was established through induction with TNF-α. The effects of AST on the expression levels of WTAP, BAX, BCL2, and TRAIL-DR4 were evaluated utilizing immunofluorescence, RT-qPCR, and Western blot analysis. Furthermore, CCK-8 and flow cytometry were used to assess MH7A cell viability, cell cycle, apoptosis, and proliferation. Then, the m6A modification of TRAIL-DR4 was elucidated via MeRIP-qPCR.

The optimal dose administration time was 50 μg/mL at 48 h. AST not only reduced the expression levels of WTAP, BCL2, BAX, TRAIL-DR4, and the m6A modification level of TRAIL-DR4 but also significantly enhanced apoptosis in MH7A cell, while inhibiting cell viability and proliferation. Furthermore, AST was capable of reversing the effect on MH7A cell proliferation and apoptosis induced by WTAP overexpression.

This study elucidates the protective role of AST on MH7A cells by attenuating m6A/WTAP-mediated apoptosis, offering novel insights into the mechanisms of AST.

Transcription factors (TF) are the central regulatory hubs of signaling pathways in eukaryotic cells. Here, we explored the abnormal expression of TF in septic-induced lung injury by sequencing.

The levels of target proteins were detected using Western Blot and Elisa. Cell function was evaluated using CCK8 and transwell assays. A double luciferase reporter assay was performed to detect interactions between target molecules.

We found that TF glioma-associated oncogene (GLI) family zinc finger 3 (GLI3) was abnormally low expressed in a lipopolysaccharide (LPS) induced acute lung injury (ALI) cell model. In an in vitro model, GLI3 overexpression promoted the proliferation and migration and inhibited apoptosis of lung epithelial cells in LPS-induced inflammatory environment. Importantly, GLI3 overexpression inhibited the secretion of inflammatory factors IL-1β, IL-6, and TNF-α. Additionally, miR-143-3p inhibited the expression of GLI3. MiR-143-3p inhibitor alleviated the cell damage caused by LPS, while knocking down GLI3 counteracted this effect, indicating that miR-143-3p downregulated GLI3 and inhibited its anti-inflammatory effect. Secreted frizzled related protein-1 (SFRP1) was upregulated in LPS-treated cells and SFRP1 promoter interacted with GLI3, suggesting that SFRP1 was a target of TF GLI3. Co-transfection with GLI3 knockdown and SFRP1 overexpression plasmids attenuated the secretion of inflammatory factors IL-1β, IL-6, and TNF-α caused by GLI3 knockdown in LPS-treated cells, indicating that SFRP1 plays an anti-inflammatory role as a GLI3 target in the ALI cell model.

miR-143-3p caused degradation of GLI3 mRNA and thus inhibited the transcription of SFRP1, leading to decreased proliferation and increased levels of inflammatory factors, providing new potential targets for the clinical diagnosis and treatment of ALI.

Benzoimidazo[1,2-a]pyrimidines are important compounds that have many useful effects in the body. They can help fight cancer, fungal infections, inflammation, and viruses. They can also help with various other health conditions. They can act as antineoplastic, antitubercular, parasitical activity, benzodiazepine receptor agonists, calcium channel blockers, potent P38 MAP kinase inhibitors, TIE-2 and/or VEGFR2 inhibitory activities, protein kinase inhibitors, and T cell activation. There are different methods to make the benzoimidazo[1,2-a]pyrimidines. Some of them dealth with the one-pot threecomponent condensation reactions of β-dicarbonyl compounds, aldehyde and 1H-benzo[d]imidazol-2-amine in the presence of catalyst. Although the synthesis of this group of compounds has been done before, and the products have been identified from the spectroscopic point of view, the kinetics and reaction mechanism have not been investigated. The strength of these calculations is that evaluation of the activation energy of various steps suggests possible mechanisms, probable mechanisms, and valuable synthetic intermediates.

In this report, seven possible mechanisms for synthesizing the benzoimidazo[1,2-a]pyrimidines have been investigated using density functional theory (DFT) at the B3LYP/6-311G** level of theory. Each synthetic route involves condensation of the benzaldehyde, indanedione and 1H-benzo[d]imidazol-2-amine molecules to yield the proposed product. The calculations showed that the suggested method has six steps; its initiation step includes the Knoevenagel reaction between indanedione and aldehyde, and the rate determining state is dehydration in the fifth step.

Six potential pathways for the reaction will occur. Then, we focused on the best pathway and studied it in detail. The ways that three chemicals-indanedione (R1), benzaldehyde (R2), and 1H-benzo[d]imidazol-2-amine (R3) react with each other were studied using ab-initio program by ChemBio3D, Gauss View, and Gaussian 09. The Density Functional Theory (DFT) using the B3LYP basis set was used to improve the arrangement of molecules involved in the three-part creation of a specific compound called 12-phenyl-5H-benzo[4,5]imidazo[1,2-a]indeno[1,2-d]pyrimidin-13(12H)-one (P).

During the study of the six mechanisms, the proposed pathway 2 is the best mechanism for this reaction because its rate-determining step has the lowest activation energy value. This route consists of 6 steps, the fifth step of which is related to the conversion of IM4 to IM5 (relative ∆E: 109.80 Kj/mol), during which a dehydration reaction is performed, and this step occurs by passing through transition state TS5 (Total Energy (Hart./particles: -1194.747403).

Esophageal Squamous Cell Carcinoma (ESCC) remains a significant global health challenge, underscoring the urgent need for the development of innovative therapeutic approaches. Ranunculus ternatus Thunb., a traditional herb, exhibits potential anticancer properties, but its mechanisms against ESCC remain poorly understood. This study integrates network pharmacology and experimental validation to explore the therapeutic effects of the ethyl acetate extract of Ranunculus ternatus Thunb. (RTE).

Potential targets of RTE and ESCC were screened using public databases. A Protein-Protein Interaction (PPI) network was constructed to identify key targets, followed by GO and KEGG pathway enrichment analyses. The predicted mechanisms were validated using in vitro assays, including cell proliferation analysis and western blot assay in ESCC cell lines.

Network pharmacology analysis identified 274 potential targets, with 14 key genes implicated in the therapeutic effects of RTE. GO analysis revealed significant involvement in the inflammatory response and apoptotic signaling pathways. KEGG pathway analysis highlighted the MAPK, Relaxin, and PI3K/Akt signaling pathways as critical mechanisms. In vitro experiments demonstrated that RTE significantly inhibited the proliferation of EC-109 and TE-13 cells by modulating the MAPK/ERK and PI3K/Akt pathways.

The study reveals that active compounds of RTE target MAPK/ERK and PI3K/Akt pathways, aligning with prior evidence. However, future studies should explore animal models to confirm efficacy.

This study provides a comprehensive understanding of the molecular mechanisms underlying the anticancer effects of RTE against ESCC. These findings underscore the potential of RTE as a promising natural compound for ESCC treatment.

The objective of this research is to demonstrate that alignment-free bioinformatics approaches are effective tools for analyzing the similarity and dissimilarity of protein sequences. All numerical parameters representing sequences are expressed analytically, ensuring precision, clarity, and efficient processing, even for large datasets and long sequences. Additionally, a novel approach for identifying previously unknown virus strains is introduced.

A novel approach is proposed, integrating the unique features of our newly developed method, the 20D-Dynamic Representation of Protein Sequences, with the K-means clustering algorithm. The sequences are represented as clouds of material points in a 20-dimensional space (20D-dynamic graphs), with their spatial distribution being unique to each protein sequence. The numerical parameters, referred to as descriptors in molecular similarity theory, represent quantities characteristic of dynamic systems and serve as input data for the K-means clustering algorithm.

Examples of the application of the approach are presented, including projections of the 20D-dynamic graphs onto 3D spaces, which serve as a visual tool for comparing sequences. Additionally, cluster plots for the analyzed sequences are provided using the proposed method.

Combining the 20D-Dynamic Representation of Protein Sequences with an unsupervised machine learning algorithm (K-means clustering) enhances its scalability. This approach is applicable to large datasets without restrictions on sequence length.

It has been demonstrated that the 20D-Dynamic Representation of Protein Sequences, combined with the K-means clustering algorithm, successfully classifies subtypes of influenza A virus strains.

Antibodies have broad applications in various fields, such as biology and medicine. The screening and preparation of highly specific and sensitive antibodies are essential research areas. Several techniques for the preparation of mouse-derived antibodies have been developed, but limited studies on rabbit-derived antibodies with a broader antibody profile and easier humanization are reported. An improved yeast surface display technique was used for rapid screening of rabbit-derived Fab antibodies.

After RNA extraction from peripheral rabbit blood, a cDNA library was obtained by reverse transcription. After recombinant vector construction, the expressed sequence in the form of Fab antibody structure was fused to the N-terminal end of Aga2p in the vector; a bidirectional promoter was inserted and successfully expressed in brewer's yeast EBY100. In addition, sequences, such as leucine zipper and inulinase signal peptide (INU), were inserted into the recombinant vector to improve the expression and stability of Fab antibody further.

A biotin-labeled salbutamol marker was synthesized, and two rabbit-derived salbutamol-Fab antibodies were screened in three weeks using fluorescence-activated cell sorting (FACS).

After antigen-binding kinetic studies, the screened antibodies demonstrated good affinity and specificity.

To explore the mechanism of action of the differential components of medicinal and edible lilies in treating depression by network pharmacology using UPLC-Q-TOF-MS technology.

The chemical composition of medicinal and edible lilies was analyzed, screening for unique medicinal compounds. Searched for depression-related targets. Constructed PPI networks. Performed GO and KEGG analyses. Built a network of differential components, and conducted molecular docking. In addition, the contents of regaloside before and after lily processing were compared.

Medicinal lilies and edible lilies have 17 main differences, including regaloside B and regaloside E. There are 179 targets for actives, 2690 for antidepressants, and 98 intersected. Core targets (7) led to 238 GO processes and 107 KEGG pathways. The molecular docking results showed that 17 components, including regaloside B, regaloside E, (25R)-3β,17α-Dihydroxy-5α- spirostan-6-one 3-O-α-L- rhamnopyranosyl-(1→2)-β- D-glucopyranoside (Named: Lilium lancifolium saponin), etc. could act on 7 potential targets such as EGFR, HSP90AA1, STAT3, TNF, etc. to exert antidepressant effects.

This study employed a network pharmacology combined with a molecular docking approach to compare the active constituents of medicinal and edible lilies in antidepressants, and their pharmacological mechanisms, both theoretically and technically. The phytoconstituents were found to act mainly by inhibiting the inflammatory response in depression. Especially Lilium lancifolium saponin may have a close relationship with antidepressants. These results provide some justification for lilies in the treatment of depression.

Diet is a modifiable factor that influences several chronic diseases, making lifelong dietary interventions critically important for reducing disease risk. Hence, this study aims to assess the potential causal relationship between diet and sleep apnea (SA).

We analyzed genome-wide association study (GWAS) data from approximately 450,000 individuals, focusing on 8 dietary intakes and GWAS statistics for 249 metabolites from the UK Biobank. Sleep apnea-related phenotypic data from 16,761 participants were sourced from the FinnGen Biobank. Furthermore, we conducted a series of two-sample Mendelian Randomization (two-sample MR) to explore the causality between diet and SA. Sensitivity analyses were conducted to assess the robustness of the two-sample MR results, and reverse MR analysis was performed to examine potential reverse causality. Multivariate MR (MVMR) analysis and mediation effect estimation were employed to evaluate the mediating roles of metabolites.

Two-sample MR analyses revealed significant causal associations between bread intake (OR=0.56, 95% CI 0.35–0.89, P =0.014), cheese intake (OR=0.67, 95% CI 0.50–0.89, P =0.006), and dried fruit intake (OR=0.61, 95% CI 0.39–0.95, P =0.029) with SA. Reverse MR analysis indicated a causal effect of SA on dried fruit intake (P < 0.05). Univariate MR analyses further identified significant causal effects of bread and cheese intakes on 2 and 32 metabolites, respectively (P < 0.05). Subsequent MVMR analysis demonstrated direct causal effects of bread and cheese intake on SA, independent of metabolite mediation (P < 0.05). Furthermore, the mediating effect of cheese intake on SA through glucose was estimated at 0.023 (90% CI 0.01–0.046), whereas other modeled mediation effects were not statistically significant.

The MR analysis in this study offers genetic evidence indicating that heightened genetic susceptibility to cheese and bread intake potentially reduces SA risk. These findings underscore and validate the significance of diet in preventing SA.

Trauma, resulting from mechanical factors, entails damage to human tissues or organs. Whether occurring during times of war or peace, trauma is prevalent, particularly skin defects arising from surgery or external injuries. The development and design of effective wound dressings have become paramount. Bingqing Gao(BQG), rooted in Chinese folk medicine, is employed explicitly in trauma treatment based on traditional Chinese medicine (TCM) theory. This study aims to elucidate how BQG facilitates full-thickness skin wound healing in Sprague Dawley (SD) rats.

Data collection commenced using two approaches: retrieval from TCM system pharmacology databases (TCMSP) and literature mining to compile the practical chemical components and targets of BQG. A drug-target network was constructed. Subsequently, disease targets related to wound healing were collected to select core targets and pathways, building a drug-disease target protein-protein interaction (PPI) network using the ClusterONE algorithm to identify core genes. Gene Ontology (GO) and KEGG enrichment analyses were conducted based on the Metascape database. Finally, molecular docking validation was performed on the screened core targets and core components. In terms of in vivo experimentation, an SD rat full-thickness skin defect model was established, and varying doses of BQG were applied. Healing area, HE staining, Masson staining, ELISA, PCR, and other methods were employed to validate cytokines, differential proteins, and pathways. The study collectively discusses the mechanism and targets by which BQG promotes full-thickness skin wound healing in SD rats.

Through network pharmacology screening, we identified various active components, including resveratrol, Lithospermic acid B, sanguiinH-2, asernestioside A_qt, kaempferol, daidzein, quercetin, apigenin, and Medicarpin. The core targets encompass Interleukin-6 (IL-6), Protein Kinase B (AKT1), Vascular Endothelial Growth Factor A (VEGFA), Interleukin-1 beta (IL-1β), Tumor Protein 53 (TP53), Epidermal Growth Factor Receptor (EGFR), Tumor Necrosis Factor (TNF), Albumin (ALB), among others. Potential signaling pathways include Phosphoinositide 3-kinase (PI3K)/AKT, Tumor Necrosis Factor (TNF), Hypoxia-Inducible Factor-1 (HIF-1), and more. Molecular docking studies suggest a robust binding interaction between the active components of BQG and disease targets, indicating a potential regulation of cytokines through the PI3K/AKTsignaling pathway, thereby promoting wound healing. The results of the in vivo experiment revealed that, in comparison to the model group, both the rhb-FGF group and BQG-H group exhibit a noteworthy increase in the expression levels of PI3K and AKT genes. Concurrently, there is a significant decrease in the levels of pro-inflammatory cytokines IL-1β, IL-6, and TNF-α. Additionally, there is a substantial increase in the levels of Transforming Growth Factor-beta (TGF-β) and Vascular Endothelial Growth Factor (VEGF).

Network pharmacology results indicate that BQG promotes wound healing through multiple components, targets, and pathways. In vivo experimental results suggest that BQG may activate the PI3K/AKTsignaling pathway, inhibit the production and release of related pro-inflammatory cytokines IL-1β, IL-6, and TNF-α, promote VEGF generation at the injury site, and enhance TGF-β signaling transduction, effectively regulates the inflammatory response at the site of injury, promotes vascular regeneration in the injury area, and induces the proliferation and migration of cells in the injury area, ultimately contributing to wound healing. This study establishes the foundation for a more profound understanding of the molecular mechanisms underlying BQG's promotion of wound healing and offers insights for future drug research on BQG.

With the accelerated aging of the population, aging has emerged as a major risk factor for osteoporosis (OP). This study aims to investigate the relationship and shared molecular mechanisms between OP and aging through various genetic approaches.

Single-cell data from the peripheral blood of osteoporosis patients, aging individuals, and healthy controls were integrated to analyze characteristic changes in cell subpopulations. Differentially expressed genes (DEGs) were then identified within core subpopulations, and Mendelian randomization (MR) analysis was employed to explore potential causal links between key genes and OP. Additionally, an OP model was established in rats, and mRNA levels of key genes were measured using RT-qPCR.

Through the integration, filtering, and analysis of scRNA-seq data, an increased proportion of CD4⁺ effector memory T (CD4⁺ TEM) cells were identified in OP and aging samples, marking them as a core subpopulation. Differential expression analysis identified 49 DEGs, and further analysis through Mendelian Randomization (MR) identified three key genes (KLRB1, NR4A2, and S100A4) significantly associated with OP. Notably, the upregulation of KLRB1 and S100A4 may enhance the interactions within T cells and with other cell subgroups. At the same time, the downregulation of NR4A2 could impede communication between T cells and other cell subpopulations. The RT-qPCR results indicated that NR4A2 was significantly downregulated in the OP group.

This study conducted a comprehensive analysis of the potential link between OP and aging, identifying CD4⁺ TEM cells as the core cell subgroup in OP and aging samples. It further revealed the causal relationship between KLRB1, NR4A2, and S100A4 and the occurrence of OP. The upregulation of KLRB1 and S100A4 may contribute to OP pathogenesis by promoting interactions between CD4+ TEM cells and other cell subgroups, providing new insights for molecular targeting and immunotherapy of OP.

Methotrexate (MTX) effectively eliminates cancerous cells but can also cause inflammation intestinal, known as mucositis. Forsythiaside A (FTA) from Forsythia suspensa has shown promise in relieving mucositis by targeting the NLRP3 pathways. Since NLRP3 inflammasome activation is negatively regulated by autophagy, this study explores how FTA-mediated autophagy affects NLRP3 inflammasome in treating MTX-induced intestinal inflammation.

Intestinal mucositis was induced in rats with MTX. FTA's impact was assessed using HE staining and ELISA. The mechanism was studied using immunofluorescence, western blot, and ELISA.

FTA treatment resulted in reduced levels of D-lactic acid and diamine oxidase (DAO) in MTX-treated rats. Western blot and immunofluorescence analyses revealed up-regulation of Beclin-1 and LC3II/I, accumulation of LC3, and down-regulation of p62 expression levels in MTX-treated rats following 40 or 80 mg/kg FTA intervention. However, when the autophagy inhibitor 3-MA was used, the intestinal pathology was exacerbated, the inflammatory scores increased, and serum levels of TNF-α, IL-1β, and IL-18 were elevated. Western blotting indicated decreased LC3II/I expression, while NLRP3, cleaved caspase 1, and cleaved IL-1β expressions were upregulated.

These findings suggested that FTA alleviated MTX-treated intestinal mucositis by activating autophagy, which in turn inhibits the NLRP3 inflammasome.

Polymerase Chain Reaction (PCR) has been a pivotal scientific technique since the twentieth century, and it is widely applied across various domains. Despite its ubiquity, challenges persist in efficiently amplifying specific DNA templates.

While PCR experimental procedures have garnered significant attention, the analysis of the DNA template, which is the experiment's focal point, has been notably overlooked. This study addresses the uncertainty surrounding the amplification of DNA fragments using conventional Taq DNA polymerase-based PCR protocols. The imperative need to characterize DNA templates and devise a reliable method for predicting PCR success is underscored.

In this study, we formulate a 72-dimensional feature vector representing a DNA template through the utilization of k-word order and modeling of physicochemical properties of double bases. Subsequently, a Support Vector Machine (SVM) model is employed to assess PCR results.

A jackknife cross-validation test is used to evaluate the anticipated success rates, resulting in an overall accuracy of 95.77%. Sensitivity, specificity, and Matthew's Correlation Coefficient (MCC) stand at 95.75%, 95.79%, and 0.915, respectively.

Magnoliae Flos (Chinese name: Xin-Yi) and Xanthii Fructus (Chinese name: Cang-Er-Zi) are Chinese herbal medicines and have been used to treat allergic rhinitis (AR). However, the therapeutic effect, active ingredients, and probable processes of a compound of Magnoliae Flos and Xanthii Fructus in the form of essential oils (CMFXFEO) in treating AR have not been reported. This study aims to determine the efficacy of the CMFXFEO on ovalbumin (OVA)-induced AR in a rat model and to use network pharmacology and molecular docking to reveal the hub genes, biological functions, and signaling pathways of CMFXFEO against AR.

Animal experiments were applied to validate the role of CMFXFEO in the treatment of AR. 20 rats were randomly divided into four groups: control group (CON, n=5), positive control group (AR, n=5), CMFXFEO-treated group (AR+CMFXFEO, n=5), and budesonide-treated group (AR+Budesonide, n=5). Rats were stimulated with OVA to induce AR. Symptom scores assessment and histo-pathomorphological evaluation was performed. The serum level of OVA-specific immunoglobulin (Ig) E was measured. Gas Chromatograph-Mass Spectrometer analysis (GC-MS) was used to identify the monomer chemical composition of CMFXFEO. The target genes of CMFXFEO were obtained by using PubChem and SwissTargetPrediction databases. The target genes of AR were screened using GeneCards, DisGeNET, and OMIM databases. The target genes were intersected using the venny2.1 website to obtain the potential therapeutic targets of CMFXFEO for treating AR and to construct the PPI network. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were used to reveal associated signaling pathways. The Sybyl tool was used to dock the CMFXFEO with key therapeutic targets molecularly.

Intranasal CMFXFEO administration significantly suppressed the allergic symptoms, reduced the inflammatory cell infiltration, and the serum level of OVA-specific immunoglobulin (Ig) E. The main components of CMFXFEO obtained through the GC-MS analysis, listed as γ-terpinene (9.4908%), limonene (7.2693%), menthol (7.1821%), β-pinene (7.1190%), β-caryophyllene (7.0396%), eucalyptol (6.1367%), linalool(5.9686%), eugenol (5.0776%). A total of 398 CMFXFEO targets and 488 AR-related targets were screened, of which 42 were common targets. The GO and KEGG pathway analyses unveiled that CMFXFEO were strongly associated with several signaling pathways, including the AGE-RAGE signaling pathway, TNF signaling pathway, and Chemokine signaling pathway. PPI network construction screened six hub genes as therapeutic targets, including STAT3, IL1B, TLR4, PTGS2, ICAM1, and VCAM1. The molecular docking verification indicated that CMFXFEO have good binding activity with therapeutic targets, and β-Pinene’s docking ability with TLR4 is particularly prominent.

The anti-inflammatory and anti-allergic effects of CMFXFEO are to inhibit the infiltration of inflammatory cells in the OVA-induced AR rat model. The results of the network pharmacology and molecular docking deduced that the CMFXFEO may have the potential to treat AR by multiple pathways through relieving inflammatory, anti-oxidative stress response, and modulating the immune system.

The goal of this research was to formulate mucoadhesive gels using hydroglyceric extracts of Cistus creticus L. and Inula viscosa (L.) Aiton, either separately or in combination, utilizes carboxymethyl cellulose and detects their physicochemical characteristics and safety for oromucosal cells and antimicrobial (antibacterial, antifungal, and antiviral) efficacy to assess their performance.

Using LC-HRMS, the extracts of C. creticus and I. viscosa were examined. Evaluations were conducted on the formulations' viscosity, cytotoxicity-cell proliferation controls, texture, antibacterial activity, pH, and organoleptic properties. The minimal inhibitory concentrations and microbroth dilution tests were used to assess the effectiveness of the formulations.

The pH, organoleptic, and physical characteristics of each formulation have been determined to be appropriate. The research results demonstrated that I. viscosa contributed antiviral efficacy to the formulations linked to dose-dependent activities against all examined mouth pathogens, whereas C. creticus provided antibacterial and antifungal efficacy. The formulation containing C. creticus extract alone was the most cytotoxic, whereas the formulation including I. viscosa extract alone was the least cytotoxic against gingival fibroblast cells, according to the findings of tests on cell proliferation and cytotoxicity.

The formulation contained a 32% 1:1 mixture of I. viscosa and C. creticus hydroglyceric extracts was detected as safe with acceptable cytotoxicity along with antibacterial and antiviral effectiveness, were encouraging for future investigations.

Shengyang Yiwei Decoction showed efficacy in idiopathic membranous nephropathy treatment, and this study aimed to assess the underlying molecular mechanisms.

Rats with passive Heymann nephritis were divided into the model group, the Shengyang Yiwei Decoction group, the JAK2 inhibitor group, and the STAT3 inhibitor group. Healthy rats served as the normal control. 24-hour urinary protein excretion, IgG deposition, renal histopathology, the expression levels of synaptopodin, nephrin, podocalyxin, interferon-γ, interleukin-4, T-box expressed in T cells, GATA binding protein-3, and relevant pathway proteins were measured.

Within the model group, a notable elevation in the 24-h urinary protein level was observed, accompanied by evident IgG deposition, increased glomerular volume, eosinophilic deposits, diminished expression of podocyte marker proteins, and a discernible imbalance in Th1/Th2 cellular immunity. Conversely, in Shengyang Yiwei Decoction and both inhibitor groups, enhancements were observed across the aforementioned indexes.

Shengyang Yiwei Decoction may reduce glomerular podocyte injury through the suppression of the JAK2/STAT3 signaling pathway and modulation of the Th1/Th2 immune balance.

Betanin (BTN), the betacyanin present in the red beetroot, has antioxidant, anti-inflammatory, and apoptotic properties. In this study, we assessed the anti-inflammatory and apoptotic effect of BTN on collagen-induced arthritis (CIA).

The rats were arbitrarily separated into four sets: Normal, CIA, CIA+BTN (25 mg/kg bw), and CIA+BTN (50 mg/kg bw). The hematological, biochemical markers, cytokines, inflammatory enzymes, histopathology of the ankle joint, and protein expression of inflammatory and apoptotic proteins were studied.

Inflammatory enzymes, histopathological variations, cytokines generation, and joint inflammation were strongly alleviated, and apoptosis was augmented by BTN in a concentration-dependent manner. Bcl-2 and MAPK/NF-κB proteins were reduced, while the caspase-3, caspase-9, and Bax were intensified. The anti-rheumatic action of BTN was correlated to the attenuation of the MAPK/NF-κB pathway, which suppresses cytokine production, inflammation, and reduced cartilage impairments.

These outcomes recommend that BTN can be employed as a strong healing alternative for RA management.

TSPOAP1 antisense RNA 1 (TSPOAP1-AS1) is a long non-coding RNA (lncRNA) that has received widespread attention in oncology research in recent years. Its role and mechanism in some cancers have gradually been revealed. However, it is not clear what role TSPOAP1-AS1 plays in cervical cancer (CESC).

In this study, bioinformatic analysis and experimental validation were carried out to investigate the relationship between TSPOAP1-AS1 and CESC.

The relationships between clinical characteristics in patients with CESC, TSPOAP1-AS1 expression, prognostic factors, regulation network, and immune infiltration of TSPOAP1-AS1 were evaluated using statistics and The Cancer Genome Atlas database. Real-Time Quantitative Reverse Transcription PCR was used to test TSPOAP1-AS1, miR-17-5p, and AGFG2 expression in CESC cell lines.

CESC patients exhibited markedly reduced expression of TSPOAP1-AS1. There was a significant correlation between low expression of TSPOAP1-AS1 in CESC patients and the clinical stage (p < 0.05), weight (p < 0.05), and BMI (p < 0.05). Lower expression of TSPOAP1-AS1 in patients with CESC was associated with poorer overall survival (OS) (p = 0.014) and disease-specific survival (DSS) (p = 0.030). There was also an independent correlation between high expression of TSPOAP1-AS1 (p = 0.036) and DSS in patients with CESC. TSPOAP1-AS1 was involved in the ribosome, oxidative phosphorylation, antigen processing and presentation, cell adhesion molecules (CAMs), the chemokine signaling pathway, neuroactive ligand-receptor interaction, and primary immunodeficiencies. The infiltration of immune cells and the expression of TSPOAP1-AS1 were found to be correlated. A ceRNA network of TSPOAP1-AS1/miR-17-5p/AGFG2 was constructed in CESC. In CESC, a ceRNA network involving TSPOAP1-AS1/miR-17-5p/AGFG2 was successfully established. When comparing CESC cell lines with HcerEpic, the expression of TSPOAP1-AS1 and AGFG2 decreased significantly, and the expression of miR-17-5p increased significantly.

In CESC patients, low expression of TSPOAP1-AS1 was associated with poor survival and immune infiltration. It may be effective to use TSPOAP1-AS1 as a biomarker of prognosis and therapeutic target in CESC.

Dental root canal failure is a disease caused by gram-positive bacteria, Enterococcus faecalis. The disease is caused by the bacterial cell wall consisting of a peptidoglycan layer that protects the bacteria from internal osmotic pressure. Peptidoglycan biosynthesis includes many enzymes, such as MurA, Penicillin-binding protein (PBP), and SrtA. Herbal plants are a source of bioactive compounds, including antibacterial agents. There is information that red betel leaves, also known as Piper crocatum, contain active substances such as flavonoids, terpenoids, and steroids. However, there is no additional information on the antibacterial properties of P. crocatum and the molecular mechanisms that affect the cell wall of E. faecalis ATCC 29212 bacteria.

This study aims to determine the antibacterial activity of the extract in vitro, screen and study the antibacterial compounds of red betel leaves against oral pathogenic bacteria, namely E.faecalis ATCC 29212 through molecular docking.

The n-hexan:ea (9:1) fraction of P. crocatum extract was tested for inhibition zones against E. faecalis ATCC 29212 bacteria, fractions that had positive results were then identified using the LC-MS method. The LC-MS resulting compounds were tested using In Silico.

Antibacterial in the n-hexane: ethyl acetate (9:1) fraction of Red Betel Leaf has the best concentration of 10% with a moderate inhibition zone category. LC-MS test results identified compounds including Longicamphenylone, m/z 207, Nootkatone m/z 219, and Tridecanal m/z 221. Molecular interactions between these compounds with target proteins, namely MurA, PBP, and SrtA, show lower binding affinity values than natural ligands and positive controls for each protein.

Nootkatone compounds demonstrated potential as MurA and PBP inhibitors, while Longicamphenylone compounds showed potential as SrtA inhibitors. Both compounds have the potential to inhibit peptidoglycan biosynthesis and bacterial cell wall formation through docking simulations.

In recent years, there has been a rise in the incidence of renal cell carcinoma (RCC), with metastatic RCC being a prevalent and significant contributor to mortality. While a regulatory role for microRNAs (miRNAs) in the development and progression of RCC has been recognized, their precise functions, molecular mechanisms, and potential clinical implications remain inadequately elucidated. Hence, this study aimed to explore the role of miR-507 in RCC and identify STEAP3 as a downstream target of miR-507.

Bioinformatics analysis was used to analyze the expression of miR-507 and STEAP3 in RCC specimens. CCK-8, Transwell, and flow cytometry assays were used to assess the function of miR-507 in RCC cells. The connection between miR-507 and STEAP3 was confirmed through a luciferase reporter assay. The expression level of STEAP3, p53, and xCT was analyzed by western blotting.

Bioinformatics analysis showed that miR-507 was expressed at low levels in RCC tissues and was linked to poor overall survival. STEAP3 was found to be significantly upregulated in RCC. Further, STEAP3 was shown to be targeted by miR-507. High levels of miR-507 reduced the expression of STEAP3, leading to stagnant cell viability, apoptosis, and migrative capacity. Whereas miR-507 knockdown reverted such a tendency. The study also discovered that miR-507 exerted its inhibitory effect through the op53/xCT pathway.

Within RCC, miR-507 modulates the expression of SETAP3/p53/xCT axis, exhibiting a tumor suppressive effect. These discoveries offer present prospective biomarkers for both surveillance and treatment of RCC.

As a classical formula to invigorate blood circulation, Huoxue Tongluo Qiwei Decoction (HTQD) can effectively treat hypertensive erectile dysfunction (ED), but its exact mechanism of action is not yet clear. The goal of this research was to explore the potential mechanism of HTQD in improving hypertensive erectile dysfunction in rats through transcriptomics, network pharmacology, and associated animal experimentations.

The HTQD chemical constituents were screened using high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Furthermore, transcriptomics analysis was performed via mRNA sequencing to identify significantly differentially expressed proteins. Moreover, the key target proteins of HTQD in the treatment of hypertensive ED were screened by network pharmacology and transcriptomics. In addition, the endothelial cells of the corpus cavernosum were assessed using hematoxylin-eosin staining. The transcript and protein expressions were evaluated via western blotting and Real-time reverse transcription-quantitative polymerase chain reaction (RT-qPCR).

The network pharmacology and transcriptome mRNA sequencing revealed that KCNE1 may be the target protein of HTQD in improving hypertensive ED. After HTQD treatment, the systolic and diastolic blood pressure (BP) of hypertensive rats decreased, the number of erections increased, and the pathological structure of the penis was improved. Moreover, HTQD downregulated the protein and mRNA expression of AngII, AT1R, DAG, and PKCε, whereas it up-regulated the transcript and protein expression of KCNE1.

HTQD may activate the PKCε pathway through AngII, inhibit the expression of KCNE1 protein, relax vascular smooth muscles, and improve erectile function.

The objective of this study is to analyze and identify the main chemical components and blood-absorbed components of Xuantu Granules and predict their pharmacological substance basis and mechanism in the treatment of DKD.

A DKD rat model was established by feeding SD rats a high-fat and high-sugar diet and administering intraperitoneal injections of streptozotocin (STZ). The therapeutic effect of Xuantu granules was evaluated. Drug-containing serum was prepared after gavage, and the major chemical components of Xuantu Granules and the drug-containing serum were detected using UHPLC-Q-Exactive-HRMS. Blood-absorbed components were identified based on retention time, mass-to-charge ratio, and MS/MS spectrum. Blood-absorbed components’ target proteins were searched using the CTD, SwissTarget, BindingDB, and TargetNet databases. DKD disease target genes were screened from the GEO database using WGCNA. A “bioactive blood-absorbed component-target-disease” PPI network was constructed using Cytoscape software, and the key clustering subnetworks were identified by MCODE plugin. GO functional analysis and KEGG pathway enrichment analysis were performed on subnetworks.

Xuantu Granules lowered fasting blood glucose, improved renal function, reduced proteinuria, and improved renal tissue pathological changes in DKD rats. 36 chemical components were identified, among which 12 compounds, including β -Carboline-1-propionic acid, Morin, Afzelin, Schizandrin, Gomisin A were identified as blood-absorbed components. Bioinformatics analysis indicated that AKT1, TNF, TP53, IL6, SRC, IL1B, EGFR, JUN, BCL2, and CASP3 might be the main therapeutic targets. The involved pathways included the IL-17 signaling pathway, PI3K-Akt signaling pathway, AGE-RAGE signaling pathway in diabetic complications and so on.

Xuantu Granules may exert therapeutic effects on DKD through multiple targets and pathways.

This study aims to explore the relevant biomarkers in breast cancer (BC).

Kinesin family member 4A (KIF4A) is a member of the Kinesin 4 subfamily of kinesin-related proteins, which has already been investigated in diverse types of tumors.

Our current study aims to investigate the involvement of KIF4A in BC.

KIF4A expression level was firstly predicted based on the data from the Cancer Genome Atlas (TCGA) and then assessed in BC cells. Subsequently, after silencing KIF4A, its effects on BC cell proliferation and metastasis, as well as on immune-related cytokines, were assessed by cell counting kit-8 (CCK-8), 5-Ethynyl-2'-deoxyuridine (EdU) staining and quantitative Polymerase Chain Reaction (qPCR). Next, western blotting assays were used to detect the expression and phosphorylation levels of transforming growth factor-beta 1 (TGF-β1) and small mothers against decapentaplegic 3 (Smad3) in BC cells after KIF4A silencing and the role of the pathway was verified by Smad3 inhibitor (SIS3).

KLF4A was highly expressed in BC, and silencing of KIF4A repressed the proliferation and metastasis potential of in-vitro cultured BC cells, concurrent with the reduction of CDH2, VIM, and SNAIL levels, yet the increase in the expression of CDH1. In the meantime, KIF4A knockdown diminished the levels of IL4, IL10, and TGFB while promoting those of IL1B and IL6 in BC cells. Further, enhanced phosphorylation of Smad3 was observed in BC cells, and the intervention of SIS3 restrained the proliferation and metastasis potential of BC cells and reduced the expression levels of CDH2, VIM, and Snail whilst promoting that of CDH1. Additionally, SIS3 intervention increased IL1B and IL6 levels and decreased IL4, IL10 and TGFB levels in BC cells.

This study preliminarily explored the involvement of KIF4A and TGF-β1/Smad3 together in BC, which may provide another insight into the management of BC in clinical practice.

Reproductive endocrine disorder can impair endometrial receptivity, preventing embryo implantation and increasing miscarriage risk. Impaired endometrial receptivity contributes significantly to female infertility. Inflammatory signaling pathways including the IL-6/STAT3 pathway help embryos implant. Therefore, it is crucial to explore the relationship between the IL-6/STAT3 signaling pathway and endometrial receptivity.

To investigate the mechanism by which Bushen Zhuyun decoction (BSZY) enhances endometrial receptivity in rats through the IL-6/STAT3 signaling pathway.

Mifepristone-induced poor endometrial receptivity models of female SD rats were established, followed by histopathological observation. ELISA was used to measure serum sex hormones and VEGF. Western blotting or IHC was used to measure steroid receptors, IGFBP1, and IL-6/STAT3 pathway activation in the uterus during each estrus cycle and early gestation of normal rats. The Treg/Th17 balance was assessed using flow cytometry.

Significant differences were found in the protein expressions of steroid receptors, IL-6, STAT3, and p-STAT3 during each estrus cycle and early gestation of normal rats. The protein expressions of STAT3 and PR were strongly correlated with each other. BSZY notably improved uterine morphology increased the expression of implantation markers and raised the serum concentrations of sex hormones and VEGF. BSZY enhanced the expressions of IL-6 and its receptors and restored the expressions of STAT3 and p-STAT3 in the uterus of pregnant rats. In addition, BSZY effectively restored the Treg/Th17 balance in the peripheral blood of pregnant rats.

BSZY enhances endometrial receptivity and promotes decidualization in SD rats via the IL-6/STAT3 signaling pathway.

Increasing research has proved that microglial activation, polarization, and inflammatory response in the brain affect the pathology of Alzheimer's disease. Hence, employing reagents targeted to microglial functions to optimize the brain microenvironment may become a promising therapeutic method for Alzheimer's disease.

The phagocytosis and clearance of Aβ1-42 were detected using western blot and immunofluorescence assay. The cell viability was determined via 3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) or cell counting kit-8 (CCK-8) assay. The load of pro-inflammation, in addition to anti-inflammation factors, was measured through an enzyme-linked immunosorbent (ELISA) assay. Flow cytometry was employed to estimate the apoptotic cells. The protein level related to microglial polarization and neuronal injury was detected via western blot. The length of the neuronal synapse was investigated using an immunofluorescence assay.

Dulaglutide significantly promoted microglia to phagocytose and removed the Aβ plague. Additionally, dulaglutide treatment inhibited the production of pro-inflammatory factors, including tumor necrosis factor (TNF)-α, interleukin -1β, and IL-6, whereas it increased the load of anti-inflammatory molecules, such as IL-10 affected by Aβ1-42 exposure. Further investigation verified that Aβ1-42 down-regulated YM1/2 positive M2 microglial polarization phenotype but up-regulated cyclooxygenase-2 (Cox2) positive M1 microglia. However, treating with dulaglutide effectively counteracted these effects. Moreover, dulaglutide dramatically recovered primary cortical neuron cell viability and inhibited cell apoptosis influenced by Aβ1-42. Furthermore, the dulaglutide also reversed neuronal synapse injury after exposure to Aβ1-42.

Altogether, this investigation verified that dulaglutide improved Aβ-induced inflammation and neuronal injury by mediating the activation and polarization of microglia, thereby alleviating Alzheimer's disease efficiently.

This study aimed to develop and characterize DOX-TPP/HA-ss-OA nanoparticles, utilizing the mitochondria-targeting prodrug doxorubicin-triphenylphosphine (DOX-TPP) and a reduction-sensitive amphiphilic polymer, hyaluronic acid-disulfide-oleic acid (HA-ss-OA). The research focused on evaluating the drug release behavior of these nanoparticles under varying glutathione (GSH) concentrations and their anti-tumor activity in vitro.

DOX-TPP/HA-ss-OA nanoparticles were prepared using probe ultrasound technology. The study examined the impact of different organic solvents on drug loading capacity and encapsulation efficiency to determine the optimal conditions. A single-factor experimental design was used to optimize the formulation process. Key parameters, including particle size and zeta potential, were measured to assess nanoparticle stability and performance. The dynamic dialysis method was employed to evaluate the reduction-sensitive drug release characteristics in media with different GSH concentrations. The MTT assay was used to analyze the growth-inhibitory effects of the nanoparticles on human breast cancer cells (MCF-7) and drug-resistant cells (MCF-7/ADR).

The optimized preparation process for DOX-TPP/HA-ss-OA nanoparticles included a drug dosage of 2.0 mg, an oil-to-water volume ratio of 1:5, ultrasonic power of 500 W, and ultrasonic time of 15 minutes. The nanoparticles had an average particle size of 203.72 ± 2.30 nm and a zeta potential of 25.82 ± 0.58 mV, indicating favorable stability and effective drug delivery properties. The nanoparticles exhibited a slow, sustained release of DOX-TPP in pH 7.4 phosphate buffer solution (PBS) and accelerated release in high GSH concentrations, demonstrating reduction-responsive drug release. In vitro studies showed that DOX-TPP/HA-ss-OA nanoparticles significantly inhibited the proliferation of MCF-7 and MCF-7/ADR cells in a dose-dependent manner, with enhanced efficacy compared to free DOX and other formulations.

DOX-TPP/HA-ss-OA nanoparticles demonstrate excellent reduction sensitivity, effective tumor cell growth inhibition in vitro, and the ability to overcome drug resistance. Including particle size and zeta potential measurements supports their suitability as drug carriers, highlighting their potential for targeted cancer therapy and further development.

Colorectal cancer is one of the common malignant tumors in clinical practice, and traditional Chinese medicine, as an important adjuvant treatment method, plays important roles in the treatment of malignant tumors.

This study aims to explore the mechanism of action of the Qizhu anti-cancer recipe on colorectal cancer through transcriptome sequencing.

The control group and Qizhu anti-cancer recipe group were established separately, and sequencing of the cells of the two groups was performed using the Illumina sequencing platform. Two sets of Differentially Expressed Genes (DEGs) were screened using the DESeq2 algorithm, and Principal Component Analysis (PCA), Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), Reactome, Disease Ontology (DO), and Protein-Protein Interaction (PPI) were used to comprehensively analyze the molecular functions and signaling pathways enriched by DEGs.

A total of 122 DEGs were identified through differential analysis, including 24 upregulated genes and 98 downregulated genes. GO analysis showed that DEGs were mainly enriched in functions such as alkaline phase activity, ion transport, cell differentiation, etc.; KEGG analysis showed that DEGs were mainly enriched in pathways such as Thiamine metabolism, apoptosis, signaling pathways regulating pluripotency of stem cells, cellular senescence and so on. Reactom analysis showed that DEGs were mainly enriched in response pathways such as EGR1,2,3 bind to the NAB2 promoter, EGR binds ARC gene, EGR-dependent NAB2 gene expression, etc.; DO analysis showed that differentially expressed genes were mainly enriched in diseases such as disease of cellular proliferation, disease of anatomical entity, organ system cancer, etc.; PPI analysis identified key differentially expressed genes, including DDIT3, CHAC1, TRIB3, and ASNS.

Based on transcriptome sequencing and bioinformatics analysis, it was found that the Qizhu anti-cancer recipe may involve DEGs and signaling pathways in the treatment of colorectal cancer. Our study may provide potential drug targets for developing new treatment strategies for colorectal cancer.

The You-gui pill (YGP) is a classical compound used for treating anti-diabetic erectile dysfunction (DMED). However, the specific active ingredients responsible for its effects on DMED and their mechanisms remain unclear.

In this paper, we used data mining techniques to analyze high-frequency herbs and herb combinations used in Chinese medicine for the treatment of DMED based on existing literature. Using network pharmacology to study the active components and mechanism of action of YGP against DMED, molecular docking was used to analyze the interactions of the active components with major structural proteins, nonstructural proteins, and mutants. Also, the therapeutic effect of YGP on hyperglycemic modelling and its underlying mechanisms were experimentally validated in CCEC cells by analyzing the expression of its relevant target mRNAs.

Network pharmacological analysis identified the three core components of YGP as quercetin, kaempferol, and β-sitosterol, and constructed a PPI network map of common targets of YGP and DMED, which included HIF-1α, ALB, Bcl-2, INS, IL-1β, IL-6, TNF-α, CASP3, and TP53. Combined with molecular docking results, these targets had a strong binding affinity between them and the active ingredient compounds, with the highest affinity for HIF-1α and TNF-α. During the in vitro cellular assay validation, the HIF-1α, ALB, Bcl-2, TNF-α, and IL-6 mRNA in CCECs cells showed positive regulation after YGP intervention.

The combination of “data mining - network pharmacology - molecular docking - experimental validation” provides a powerful methodological basis for the study of the main active components and mechanism of action of YGP against DMED, as well as the development and application of the drug.

The TAp73 gene is an anti-cancer gene that also affects the junction between Sertoli and germ cells. Inhibition of this gene causes infertility in male mice. Our previous research proved that Wuzi-Yanzong-Wan (WZYZW) can protect spermatogenesis and maturation by preventing TAp73 inhibition.

This study aimed to investigate the effect of drug-containing serum of WZYZW on the defect of cell-cell junctions in the Sertoli-germ cells co-culture system in vitro.

LC-HRMS was used to analyze the content of active ingredients in WZYZW-medicated serum. Then, primary extraction and co-culture of germ cells and Sertoli cells were carried out. Co-cultured cells were added with PFT-α to induce the TAp73 inhibition model, with WZYZW-medicated serum at 2.5%, 5%, and 10% treated in parallel. Sloughing of germ cells from Sertoli cells was calculated. Transmission electron microscopy (TEM), Immunofluorescence, qRT-PCR, and western blot methods were employed.

The drug-containing serum of WZYZW contained schisandrin, hyperoside, geniposidic acid, ellagic acid, and quercetin. Using TEM assay, we observed restoration of the desmosome-like (Des), tight junctions (TJ), and basal ectoplasmic specialization (ES) structure following WZYZW treatment. WZYZW caused inhibition of peptidase and protease inhibitors (tissue inhibitor of metalloproteinase-1 (TIMP1), Serpina3n) by immunofluorescence analysis. Western blot and qRT-PCR analysis revealed that WZYZW was able to ameliorate the expressions of peptidase and protease inhibitors and cell adhesion factors, such as TAp73, TIMP1, Serpina3n, Desmocollin-3, N-cadherin, and Nectin-2.

WZYZW-medicated serum could prevent the defect of cell-cell junctions between Sertoli-germ cells co-culture system in vitro by up-regulating the expression of TAp73.
