Ginsenoside Rg5:Rk1 exhibits anti-adipogenic activity in 3T3-L1 cells by downregulating the STAT3/PPARγ/CEBPα signaling pathway, suggesting potential as a natural anti-obesity agent.
Rg5:Rk1 inhibits adipogenesis in vitro; leaves open clinical translation for obesity.
Background: Obesity, a global health problem and a chronic disease, is associated with increased risk of developing type 2 diabetes and coronary heart diseases. 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.

Simu et al. (2017) studied Obesity (Adipogenesis). Ginsenoside Rg5:Rk1 vs. MDI-treated cells (positive control) was evaluated on Intracellular lipid accumulation and triglyceride content (p=<0.01). Ginsenoside Rg5:Rk1 treatment significantly inhibited lipid droplet accumulation and decreased triglyceride content in 3T3-L1 adipocytes by downregulating the STAT3/PPARγ/CEBPα signaling pathway.
