Inflamed epicardial fat (EAT) accumulation around the myocardium and coronaries is a risk factor for cardiovascular disease. Glucagon-like peptide receptor-agonists 1 improves the insulin response and reduces EAT thickness. We aimed to demonstrate the effect of semaglutide on proinflammatory epicardial adipogenesis with paracrine effects on cardiomyocytes. Biopsies or isolated stromal cells from subcutaneous adipose tissue and EAT of 67 patients undergoing open-heart surgery were studied by real-time quantitative polymerase chain reaction, proteomics, and metabolic assays. Adipogenesis assay and paracrine effect over atrial cardiomyocytes determined that semaglutide treatment modulates proinflammatory adiposity markers FABP4 and sPLA2 in epicardial adipogenesis with a paracrine effect in atrial cardiomyocytes.

Glucagon-like Receptor Agonists

Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...

GPCRs Regulate Adenylyl Cylase Activity

Some GPCRs transmit signals through adenylyl cyclase (AC), a transmembrane enzyme. AC helps synthesize second messenger cyclic adenosine monophosphate (cAMP). AC catalyzes cyclization reaction and converts ATP to cAMP by releasing a pyrophosphate. The pyrophosphate is further hydrolyzed to phosphate by the enzyme pyrophosphatase, which drives cAMP synthesis to completion. However, cAMP is rapidly degraded to 5′ AMP by the enzymes phosphodiesterase (PDE), preventing overstimulation of...
