{Abstract}: OBJECTIVE: Madecassoside (MA) is a triterpene derived from Centella asiatica that has been recognized for its antioxidant and anti-inflammatory properties in various disease models. However, its direct impact on cultured white adipocytes and the underlying mechanisms, mainly through gene knockdown, have not been thoroughly explored.
METHODS: Western blot analysis was utilized to assess the expression levels of various proteins, while oil red O staining was used to measure lipid deposition. The adipocyte shapes were confirmed using H&E staining.
RESULTS: MA treatment enhanced browning and lipolysis in 3T3-L1 adipocytes and adipose tissue from experimental mice while suppressing lipogenesis. Furthermore, MA treatment increased the expression of PPARĪ± and FGF21 in 3T3-L1 adipocytes as well as the secretion of FGF21 into the culture medium. Knockdown of PPARĪ± or FGF21 using siRNA diminished the effects of MA on lipid metabolism in cultured adipocytes.
CONCLUSIONS: These findings demonstrate that MA promotes thermogenic browning and lipolysis while inhibiting adipocyte lipogenesis, thus showing the potential for attenuating obesity. The study suggested that MA could be a viable therapeutic approach for treating obesity.
