Background: Abundant studies have shown that non-coding RNA is connected with tumor cell growth, migration and invasion. As a newly discovered non-coding RNA, WDFY3-AS2 has gradually emerged in the molecular mechanism of various tumors and has a potential prospect as a biological indicator of tumor prognosis. This review describes the pathophysiological mechanism and prognostic value of WDFY3-AS2 in different cancers. Objective: This review reveals the changes and roles of WDFY3-AS2 in many tumors and cancers. The change of WDFY3-AS2 can be used as a cancer biomarker and plays an important role in improving tumor growth, migration and invasion. WDFY3-AS2 is unique because it can be considered a prognostic marker for many tumors and is of great significance for clinical diagnosis and treatment. WDFY3-AS2 shows the potential prognostic value and the prospect of therapeutic targets in various tumors. Methods: PubMed reviewed the related literature to analyze and summarize the regulatory molecular mechanism of WDFY3-AS2 in various tumors and its value as a prognostic indicator. Results: The abnormal expression of LncRNA WDFY3-AS2 in many cancers was connected with the poor prognosis of cancer patients, including diffuse glioma, hepatocellular carcinoma, ovarian cancer, esophageal cancer, triple-negative breast cancer, Clear Cell Renal Carcinoma, Esophageal squamous cell carcinoma, Lung adenocarcinoma, which participated in the recovery of orthodontic teeth. WDFY3-AS2 has revealed the cellular process of cancer cell growth, migration, and invasion. Conclusion: The molecular mechanism of LncRNA WDFY3-AS2 regulating tumor specifically proves that WDFY3-AS2 has a good prospect in the biological index of prognosis or clinical treatment target of cancer patients.

Background: The change of lncRNA expression is known to affect the progression of tumors. This has fueled numerous investigations aiming at the mystery of lncRNA. Clear lncRNA has been the hotspot of antisense RNAs research. More and more lncRNAs have been proven to take effect as oncogenes of multitudinous cancers and accelerate tumor progression. This review elucidates the pathophysiological functions of lncRNA DLGAP1-AS1 and lncRNA DLGAP1-AS2 in a variety of tumors. Methods: Via systematic analysis and in-depth study about relevant articles in PubMed, this article analyzes and summarizes the mechanism of antisense transcripts DLGAP1- AS1 and DLGAP1-AS2 in tumor development. Results: DLGAP1-AS1 and DLGAP1-AS2 can exert their effect as oncogenes on various cancers. The expression of DLGAP1-AS1 is aberrantly high in various tumors, including GC, BC, HCC, glioblastoma and CRC. Concurrently, in LC, RC, HCC, GC, glioma and CCA, DLGAP1-AS2 is also discovered to be highly expressed. And they have a strong pertinence with a poor prognosis. The disorder of DLGAP1-AS1 and DLGAP1- AS2 in different tumors has different malignant impacts on tumors, not only to invasion, apoptosis, multiplication and EMT of tumor cells but also to drug resistance and radioresistance. In addition, DLGAP1-AS2 was revealed to have the ability to predict the prognosis of WT and RCC. Conclusion: The regulatory effects of DLGAP1-AS1 and DLGAP1-AS2 on tumors make them possible to be clinical markers for the early diagnosis of tumors and effective therapeutic targets.

Targeting the tumor microenvironment is a promising strategy to prevent metastasis, overcome acquired drug resistance, and improve the therapeutic effect. Hypoxia is one of the characteristics of the tumor microenvironment, which is mainly regulated by hypoxia-inducible factors. Hypoxia-inducible factors (HIFs) including HIF-1α, HIF-2α, and HIF-3α, of which HIF-2α has assumed a more important role in tumor hypoxia environment. It has been demonstrated that HIF-2α plays an important role in tumor diseases, including renal cell carcinoma, breast cancer, non-small cell lung cancer, and gastric cancer, among others. Therefore, targeting HIF-2α has become one of the important strategies for treating cancers. HIF-2α inhibitors can be divided into two categories: specific inhibitors and non-specific inhibitors. The former includes synthetic monomer compounds and traditional Chinese medicine extracts. In this review, we summarized, classified, and discussed current research on the structure, structure-activity relationship (SAR), and pharmacology of HIF-2α inhibitors, which is helpful to the rational design of effective drugs for various types of malignant tumors.

Type 2 diabetes mellitus (T2DM) is one of the main causes of mortality and morbidity worldwide. It leads to various long-term complications such as diabetic nephropathy. Diabetes nephropathy is the leading cause of renal failure in patients with chronic kidney diseases undergoing hemodialysis. Hence preventing the development and progression of diabetic nephropathy is one of the main goals in the management of patients with type 2 diabetes. Sodium-glucose cotransporter 2 inhibitors of empagliflozin is a potent anti-hyperglycemic agents. In addition, it has been shown to have some pharmacologic potentials to provide renoprotective effects in patients with T2DM. In the current study, we review the available clinical data on the potential renoprotective effects of this drug from a mechanistic and molecular viewpoint.

Thrombosis is one of the most important pathogenic factors related to cardiovascular diseases. Presently, thrombin inhibitors have gradually gained prominence in clinical practice due to their unique potential, such as dabigatran. Nevertheless, the risk of bleeding is not completely eliminated, and the threats of gastrointestinal bleeding are even increased in some cases. Therefore, developing new oral thrombin inhibitors with low side effects is urgent. In this paper, we summarized recent advances in the newly synthesized and isolated thrombin inhibitors from 2000 to 2019 and their structure-activity relationships (SARs) along with structure-dependent pharmacokinetic parameters, guiding the next generation of oral thrombin inhibitors.
