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.
盐酸小檗碱(JH)是传统中药黄连的一种活性成分,已被用于预防和治疗代谢紊乱。高脂血症是包括糖尿病和肥胖症在内的众多代谢性疾病的主要潜在因素之一。因此,本研究的目的是在肥胖小鼠模型中研究JH治疗在体内的降脂作用。经JH治疗的高脂血症小鼠体重减轻,葡萄糖耐量和胰岛素敏感性得到改善。此外,与喂食高脂饮食的未治疗小鼠相比,经JH治疗的高脂血症小鼠血清甘油三酯、总胆固醇和低密度脂蛋白胆固醇水平降低,高密度脂蛋白胆固醇水平升高。值得注意的是,JH治疗改善了高脂血症小鼠肝脏中观察到的病理生理变化。在分子水平上,JH下调了高脂血症小鼠肝脏中SREBP-1c和FAS的mRNA表达水平,并诱导了PPAR-α和CPT1A mRNA的表达。这些发现表明,JH通过抑制肝脏中的脂肪生成和增强脂质氧化来改善高脂血症。
