image of PGx-Based in silico Analyses Identifies the Interactive Role of Genes, Glucose Metabolism and Dopaminergic Dysfunctional Pathways with Chronic Cocaine Use and Misuse

Abstract

Introduction

Our team conducted a pharmacogenomics (PGx) analysis to evaluate the interactions between cocaine, glucose metabolism, and functional connectivity using in-depth silico PGx methods.

Methods

Utilizing PharmGKB, we extracted PGx annotations related to cocaine, glucose, and dopamine (raw data). After filtering, we refined a list of 49 unrepeated, brain-expressed genes and examined their interactions in a protein-protein interaction (PPI) network through STRING-MODEL, identifying top candidate genes.

Results

Targeting key protein-coding genes with the highest connectivity, we identified , , and , along with their 17 connected genes. A deep dive into gene-miRNA interactions (GMIs) using NetworkAnalyst revealed that , and hsa-miR-16-5p have multiple interactions with and . Enrichment analysis Enrichr confirmed that this refined set of 17 impacts dopamine function and are interactive with dopaminergic pathways. Notably, Substance Use disorders (SUD) were the most significant manifestation predicted for the interplays among these genes.

Discussion

Reviewing all PGx annotations for the 17 genes, we found 4,665 PGx entries, among which 1,970 were significant, with a -value above 0.045. These were ultimately filtered down to 32 potential PGx annotations excluded in association with “Cocaine,” “Glucose or Diabetes,” and “Dopamine”. Accordingly, 12 Pharmacogenes represented 32 PGx-associated with Cocaine, Glucose, and Dopamine, including and

Conclusion

This PGx analysis demonstrates strong, validated connections based on prior published data and robust computational predictions. Among the findings, the gene was found to be the best-scoring gene here.
