PPARG (Peroxisome Proliferator-Activated Receptor Gamma): PPARG is a nuclear receptor that regulates the expression of genes involved in fatty acid storage, glucose metabolism, and adipocyte differentiation. It plays a central role in insulin sensitivity and is targeted by thiazolidinediones, a class of antidiabetic drugs. Its involvement in metabolic pathways makes it an important gene in the study of obesity, diabetes, and cardiovascular disease.
