초록
Elephant garlic (Allium ampeloprasum L.) has been reported to have several pharmacological effects. However, its anti-adipogenic effect and the possible molecular mechanisms have not yet been reported. In this study, we demonstrate that elephant garlic extracts suppress adipogenesis in 3T3-L1 adipocytes. Raw and steamed elephant garlic extracts (REG and SEG, respectively) suppressed the differentiation of adipocytes and cellular lipid accumulation. Of note, the anti-differentiation effect of REG treatment on 3T3-L1 cells resulted in cytotoxicity, whereas SEG-treated cells displayed no such cytotoxicity. Additionally, SEG treatment significantly reduced the adipogenesis-related gene expression of PPAR γ, C/EBPα, adiponectin, Ap2, and LPL. To our knowledge, these results are the first evidence of the anti-adipogenic effects of elephant garlic extracts on 3T3-L1 adipocytes.
