Hepatic and Peripheral Effects

Thyroid accept T3 and T4 exert control over the expression of genes central to glucose and lipid metamism. In the liver, T3 stimulates tranction of enzymes responble for gluconoogenesis and glykogenolysis, effectively raming up hepatic glucose output. Simultanéously, T3 promotes lipolysis in adipose tissue, elevating circulating free fatty acids (FFAs) that exephate insulin resistance via the randle cycle.
