The purpose of this study was to find out effects of treatment of ginsenoside Re, Rc and EGCG on mRNA expressions of leptin, hormone sensitive lipase (HSL) and resistin in 3T3-L1 adipocytes. The concentrations of EGCG were treated with $0.01{\times}10^{-7},\;0.1{\times}10^{-7},\;1{\times}10^{-7}\;and\;1{\times}10^{-6}\;or\;100{\mu}g/ml$ ginsenoside Re, Rc in culture cell for 13 days. mRNA expression of leptin wasn’’t expressed in preadipocyte but according to differentiation of adipocyte, the that of mRNA expression was decreased at gensenosids or EGCG treated cells compared with non treated adipocyte. Expression of HSL mRNA was increased in G-Re, G-Rc and EGCG treated cells compared with non treated cells. The resistin level was significantly decreased in adipocytes treated with G-Re, G-Rc and EGCG. These pattern was similar to leptin expression. These results support that treatment of gensenosides or EGCG in 3T3-L1 adipocyte resulted to affect of leptin and resistin as well as HSL mRNA levels, accordingly, levels of leptin and HSL will be acted by signalling body fat stores to the hypothalamus which in turn regulates food intake andenergy expenditure to maintain body weight homeostasis. And also regulation of resistin mRNA will prevent to diabetics attacked with obesity. In conclusion, we suggest that consumption of ginseng saponine or EGCG might prevent human diabetics or/and obesity.
