虽然已有报道BMP-9可诱导白色脂肪组织(WATS)的布朗宁并抑制高脂饮食诱导的肥胖,但详细的分子机制需要进一步阐明。我们在这里报告,MB 109,人BMP-9的重组衍生物,到肥胖小鼠的管理增强成纤维细胞生长因子21(FGF 21),代谢调节因子的基因表达,并阐明了一系列的病理症状,由于高脂肪饮食诱导的肥胖。此外,定期注射MB 109(500 μg/kg/周)降低了肝脏中脂滴的量、丙氨酸氨基转移酶(ALT)和总胆固醇的血清水平。这些结果表明,MB 109也有效治疗肥胖介导的非酒精性脂肪性肝病(NAFLD)。
Although BMP-9 has been reported to induce browning of white adipose tissues (WATs) and suppress high fat diet-induced obesity, detailed molecular mechanism needs to be further elucidated. We report here that administration of MB109, a recombinant derivative of human BMP-9, into obese mice enhanced gene expression of fibroblast growth factor 21 (FGF21), a metabolic regulator, and alleviates a spectrum of pathological symptoms due to high fat diet-induced obesity. In addition, periodical injection of MB109 (500 μg/kg/week) reduced an amount of lipid droplets in the liver, serum levels of alanine aminotransferase (ALT), and total cholesterol. These results indicate that MB109 is also effective to treat obesity-mediated non-alcoholic fatty liver disease (NAFLD).
