Abstract


Obesity is one of the risk factors for atherosclerosis. Fat accumulation and adipocyte differentiation are associated with the occurrence and development of obesity. Thus, suppression of adipocyte differentiation provides a potential anti-obesity approach. This study examined the effect of mangosteen pericarp extract (MPE) and xanthone (α-Mangostin (AM) and γ-Mangostin (GM)) on the expression of PPARγ, C/EBPα, SCD1, LPL, aP2, adipoQ, and FAS in 3T3-L1 cells. Concentrations of MPE and xanthones used were based on cytotoxic assay on 3T3-L1 cells. Three different MPE concentrations (0, 25, and 50 µg/ml) were used in this study. Likewise, three different concentrations of AM (0, 25, and 50 µM) and GM (0, 50, and 75 µM) were also used in the experiment. The expressions of PPARγ, C/EBPα, SCD1, LPL, aP2, adipoQ, and FAS genes were measured using real-time quantitative PCR. The expression of the genes was down-regulated in the group of cells treated with 50 µg/ml of MPE and 50 µM of GM. However, 25 µM and 50 µM of AM did not suppress PPARγ and SCD-1 expression. 50 µM of AM also failed to reduce aP2 gene expression. In conclusion, MPE and GM showed potential anti-adipogenesis and anti-obesity effects by suppressing the expression of PPARγ, C/EBPα, SCD1, LPL, aP2, adipoQ, and FAS genes in 3T3-L1 cells.
