Outline of Final Research Achievements	p21 is the main factor which controls cell cycle and accelerated in hepatocyte and adipocyte of obese model mice, but though cell cycle of those cells is G0 periods. Previous research has shown that overexpression of p21 decrease insulin-stimulated glucose uptake in 3T3-L1 cultured adipocytes and p21 knockout mice fed high fat diet has reduced insulin resistance. CDKs (cyclin-dependent kinases) is known as a target molecule of p21. So when several CDK inhibitors were treated in 3T3-L1 adipocytes, insulin-stimulated glucose uptake was decreased.
