Anti-obesity effects of isoacteoside on 3T3-L1 adipocytes

초록

Isoacteoside is a caffeoyl phenylethanoide glycoside found in various plant parts, such as the flower of Magnolia denudata. In particular, magnolia has been studied for its anti-obesity, anticancer, and anti-inflammatory effects. However, isoacteoside has not been extensively studied, except for its anti-inflammatory effects. In this study, the anti-obesity effects of isoacteoside were investigated in 3T3-L1 mouse pre-adipocytes. Isoacteoside treatment did not induce cytotoxicity in 3T3-L1 cells up to a concentration of 1000 mu M. The anti-obesity effects on 3T3-L1 cells were confirmed using oil red O staining. In addition, the expression of obesity-related proteins and genes, such as peroxisome proliferator-activated acceptor gamma (PPAR gamma), CCAAT/enhancer-binding protein alpha (C/EBP alpha), and perilipin (PLIN1), was determined by western blotting and qRT-PCR assays to confirm the anti-obesity effects of isoacteoside. The results of this study suggest that isoacteoside, a natural substance isolated from plant extracts, is not highly toxic to normal cells, such as pre-adipocytes, and displays anti-obesity effects in vitro.
