Abstract:
Objective To investigate the effects of tumor necrosis factor-alpha (TNF-?) on insulin sensitivity and glucose-lipid metabolism in TNF-?-induced IR mice. Methods Male C57BL/6J mice were given an intraperitoneal injection of TNF-? (H group,6?g/kg; M group,3?g/kg; L group,1?g/kg;twice daily) and saline (NC group) for 7 days. The plasma glucose and insulin were assayed during intravenous glucose tolerance test (IVGTT) and hyperinsulinemic-euglycemic clamp combined with 3-[3H] glucose as a tracer was carried out. Results After TNF-? treatment,fasting blood glucose (FBG),plasma insulin and free fatty acids (FFA) were significantly elevated in H group compared with NC,L and M groups (P
