Nonalcoholic Steatohepatitis (NASH) in OB/OB Mice Treated with Yo Jyo Hen Shi Ko (YHK): Effects on Peroxisome Proliferator-Activated Receptors (PPARs) and Microsomal Triglyceride Transfer Protein (MTP)
2007
YHK has antioxidant properties, has a hypoglycemic effect, and may reduce plasma lipid levels. In this study, we examined the hepatic expression of PPAR-α and -γ and MTP in ob/ob mice receiving or not receiving YHK. Ob/ob mice were assigned to receive oral YHK (20 mg/kg/day) fed solution (methionine/choline-deficient [MCD] diet + YHK group) or vehicle (MCD group) by gavage for 4 weeks. Liver fragments were collected for histologic examination and mRNA isolation. PPAR-α and -γ and MTP gene expression was examined by RT-qPCR. YHK treatment was associated with NASH prevention, weight loss, and reduction of visceral fat and of serum concentrations of aminotransferases in comparison to the MCD group. YHK promoted an increment in PPAR-α and MTP and a decrement in PPAR-γ mRNA contents. These findings suggest that modulation of PPAR-α and -γ and MTP RNA expression may be implicated in the protective effect of YHK in experimental NASH, limiting hepatocyte lipid accumulation.
