Abstract

Regulating adipogenesis and lipogenesis in white adipose tissue (WAT) is an efficient strategy to reduce obesity. This study investigates whether garlic scape extract (GSE) has anti-adipogenic and anti-lipogenic effects and which stage of adipogenesis is critical for its effect using 3T3-L1 cells. 3T3-L1 cells that were treated with GSE during adipogenesis and differentiation exhibited reduced peroxisome proliferator-activated receptor γ , CCAAT/enhancer-binding protein a (Cebpa) and Cebpb , acetyl-CoA carboxylase, fatty acid synthase, sterol regulatory element binding protein 1c, diacylglycerol acyltransferase 1, and perilipin 1 genes. When the cells were treated with GSE during postdifferentiation or during preadipocytes, they showed less reduction and no change, respectively. Consistent with this, lipid accumulation was strongly reduced in the cells that were treated during adipogenesis and differentiation and to a lesser extent in the cells that were treated during preadipocytes and postdifferentiation. Phosphorylation on AMP-activated protein kinase (AMPK) and its downstream proteins was increased together with increased carnitine palmitoyl transferase 1 α and phosphorylation on hormone-sensitive lipase in the cells that were treated with GSE during differentiation. In summary, GSE reduced intracellular lipid accumulation by suppressing adipogenic and lipogenic genes and proteins by possibly the activation of AMPK signaling pathway during adipocyte differentiation. This result indicates that garlic scape may have the potential to prevent obesity by regulating lipid metabolism in WAT.
