A wide variety of natural remedies have been explored for their obesity treatment potential. Objective: The anti-adipogenic effect of ginsenoside Rg5:Rk1 (Rg5:Rk1) on 3T3-L1 mature adipocytes was investigated. Materials and Methods: To elucidate the anti-obesity effect of Rg5:Rk1, a mixture of protopanaxadiol type ginsenosides isolated from Panax ginseng Meyer in a 3T3-L1 adipocytes. In order to determine the anti-obesity effect of Rg5:Rk1, based on oil Red O Staining, triglyceride (TG) content in adipose cells was assessed. Furthermore, to elucidate the possible mechanism of Rg5:RK1 effect on lipid accumulation, mRNA and protein expression analyses of adipocyte markers such as STAT3, PPARγ, CBEPα and ap2 were carried out. Results: Rg5:Rk1 treatment showed an inhibition of lipid droplet accumulation and decrease of TG content. In addition, expression of STAT3, PPARγ, CEBPα and ap2 were decreased in a dose dependent manner. Similarly, the Rg5:Rk1 treatment reduced PPARγ and CEBPα protein expression. Conclusion: Rg5:Rk1 treatment exhibits anti-adipogenic activity by down-regulation of the STAT3/ PPARg/CEBPa signaling pathway in 3T3-L1 adipocyte cell line.   %U https://www.ijbiotech.com/article_54472_a6467b675334c5d989100deb9a794013.pdf
