Upregulated: collagen synthesis genes (COL1A1, COL3A1), antioxidant genes (SOD1, SOD3), DNA repair genes (GADD45A) Downregulated: inflammatory cytokines (IL-6, TNF-), metalloproteinases (MMP-2, MMP-9), pro-fibrotic mediators Net effect: shift from tissue destruction and inflammation toward repair and remodeling This breadth of gene modulation is unusual for a single tripeptide and has generated significant research interest in fields ranging from dermatology to neuroscience

Both medications are known for their ability to cause stomach-related side effects

Researchers started 1,613 adults in the trial on 1 mg of orforglipron and increased the dose every four weeks until patients received 6 mg, 12 mg, and 36 mg, while other patients received a placebo
