Jatrorrhizine hydrochloride attenuates hyperlipidemia in a high-fat diet-induced obesity mouse model

Jatrorrhizine hydrochloride (JH) is an active component of the traditional Chinese herb Coptis chinensis, which has been used to prevent and treat metabolic disorders. Hyperlipidemia is one of the principal factors underlying numerous metabolic diseases, including diabetes and obesity. Therefore, the aim of the present study was to investigate the lipid lowering effects of JH treatment in vivo in an obesity mouse model. JH-treated hyperlipidemic mice exhibited a reduction in body weight, as well as improved glucose tolerance and insulin sensitivity. In addition, JH‑treated hyperlipidemic mice exhibited reduced serum triglyceride, total cholesterol and low‑density lipoprotein cholesterol levels, as well as increased high‑density lipoprotein cholesterol levels compared with untreated mice fed a high‑fat diet. Notably, JH treatment ameliorated the pathophysiological changes observed in the livers of hyperlipidemic mice. At the molecular level, JH downregulated the hepatic mRNA expression levels of SREBP‑1c and FAS, and induced PPAR‑α and CPT1A mRNA expression in hyperlipidemic mice. These findings suggest that JH ameliorates hyperlipidemia via the suppression of lipogenesis and the enhancement of lipid oxidation in the liver.
