JCEM:血清血管生成素样蛋白6与2型糖尿病风险

2020-03-03 xing.T MedSci原创

由此可见,血清高水平ANGPTL6与人类糖尿病的低发病率有关。在高血糖状态下ANGPTL6表达和分泌增加,以维持血糖稳态。

血管生成素样蛋白6(ANGPTL6)是一种肝素,可提高动物对胰岛素的敏感性。但是,在横断面研究中,发现糖尿病代谢综合征患者血清ANGPTL6浓度较高,这表明ANGPTL6可能被诱导以对抗高血糖症。近日,内分泌和代谢性疾病领域权威杂志Journal of Clinical Endocrinology & Metabolism上发表了一篇研究文章,研究人员旨在调查血清ANGPTL6是否可以预测糖尿病的发生,并探讨了血糖或胰岛素是否可以调节ANGPTL6的表达和分泌。

这项队列研究纳入了基线时无糖尿病的成年人,每两年对糖尿病发生情况进行随访。在基线和口服葡萄糖耐量测试(OGTT)期间测量了受试者血清ANGPTL6浓度。肝细胞系HepG2和饮食诱导的肥胖小鼠模型用于评估高血糖症和代谢综合征对ANGPTL6表达和分泌的影响。

研究人员招募了1103名基线时没有糖尿病的受试者。在为期4.22年的随访中,有113名受试者(10.2%)患了糖尿病。血清ANGPTL6与糖尿病的发生呈负相关(校正后的HR=0.77,p=0.042)。但是,糖尿病前期患者的血清ANGPTL6水平较高(p=0.018),而在OGTT期间血清ANGPTL6水平升高。在HepG2细胞中,用葡萄糖而不是胰岛素处理可诱导ANGPTL6的表达。高脂饮食喂养的小鼠肝脏ANGPTL6表达和血清ANGPTL6浓度显著高于标准饮食喂养的小鼠(所有p<0.05)。

由此可见,血清高水平ANGPTL6与人类糖尿病的低发病率有关。在高血糖状态下ANGPTL6表达和分泌增加,以维持血糖稳态。
