Houttuynia cordata (H. cordata) from the family Saururaceae is a perennial herb native to Southeast Asia. It possesses a range of medicinal properties to treat several disease symptoms including allergic inflammation and anaphylaxis. In the present investigation, we provided the molecular mechanisms underlying the role of H. cordata extract (HCE) in the prevention of high glucose-induced lipid accumulation in human HepG2 hepatocytes. HepG2 cells were pre-treated with various concentrations of HCE (0, 10, 20, 40, and 80 μg/mL) and treated with serum-free medium with normal glucose (5 mM) for 1 h, followed by exposure to high glucose (25 mM D-glucose) for 24 h. HCE significantly and dose-dependently attenuated lipid accumulation in human HepG2 hepatocytes when exposed to high glucose (25 mM D-glucose) (p < 0.05, p < 0.01 and p < 0.001 at 20, 40, and 80 μg/mL concentrations, respectively). Further, HCE attenuated the expression of fatty acid synthase (FAS), sterol regulatory element-binding protein-1 and glycerol 3-phosphate acyltransferases (GPATs). The adenosine monophosphate-activated protein kinase (AMPK) was also activated by HCE treatment when exposed to high glucose (25 mM D-glucose) in human HepG2 hepatocytes. This study suggests the hypolipidemic effects of HCE by the inhibition of lipid biosynthesis mediated through AMPK signaling, which may play an active role and can be developed as an anti-obesity agent.
