In Silico Pharmacogenomic Assessment of Glucagon-like Peptide-1 (GLP1) Agonists and the Genetic Addiction Risk Score...

Glucagon-Like Peptide-1 Receptor (GLP1R) agonists have become widespread anti-obesity/diabetes pharmaceuticals in the United States.

This article aimed to provide our current knowledge on the plausible mechanisms linked to the role of Ozempic (Semaglutide), which is generalized as one of the anti-addiction compounds.

The effects of GLP1R agonists in Alcohol Use Disorder (AUD) and substance use disorder (SUD) are mediated, in part, through the downregulation of dopamine signaling. We posit that while GLP1R agonism could offer therapeutic advantages in hyperdopaminergia, it may be detrimental in patients with hypodopaminergia, potentially leading to long-term induction of Suicidal Ideation (SI). The alleged posit of GLP1 agonists to induce dopamine homeostasis is incorrect. This study refined 31 genes based on the targets of Ozempic, GLP1R, and related enzymes for SI and 10 genes of the Genetic Addiction Risk Score (GARS) test. STRING-MODEL refined 29 genes, and further primary analyses indicated associations of GLP1R with DRD3, BDNF, CREB1, CRH, IL6, and DPP4.

In-depth silico enrichment analysis revealed an association between candidate genes and depressive phenotypes linked with dopaminergic signaling. Finally, through primary and in-depth silico analyses, we demonstrated multiple findings supporting that GLP1R agonists can induce depression phenotypes.

Our findings suggest that associated polymorphisms seem to have overlapping effects with addictive behaviors of Reward Deficiency Syndrome (RDS) and dopamine regulation. Consequently, GLP1R agonists may represent a double-edged sword, potentially triggering both antiaddictive effects and SI by exacerbating depressive phenotypes. Thus, we encourage the scientific community to perform further empirical clinical studies to confirm this proposed pathway.
