Abstract
In this study, we examined the effects of Jeju dwarf bamboo (Sasa quelpaertensis Nakai) extract (JBE) and p-coumaric acid (CA) on oleic acid (OA)-induced lipid accumulation in HepG2 cells. JBE and CA increased the phosphorylation of AMP-activated protein kinase (AMPK), and acetyl-CoA carboxylase (ACC) and the expression of carnitine palmitoyl transferase 1a (CPT1a) in OA-treated HepG2 cells. Additionally, these compounds decreased sterol regulatory element-binding protein-1c (SREBP-1c), fatty acid synthase (FAS), and OA-induced lipid accumulation, suggesting that JBE and CA modulate lipid metabolism in HepG2 cells via the AMPK activation pathway.
