【摘要】:生物钟基因包括外周生物钟基因和中枢生物钟基因。目前发现的生物钟基因主要有芳香烃受体核转位蛋白样1基因(BMAL1)、时钟基因(CLOCK)、隐色素基因1(Cry1)、隐色素基因2(Cry2)、周期基因1(Per1)、周期基因2(Per2)、周期基因3(Per3)等。研究表明外周生物钟基因和中枢生物钟基因表达改变均与糖尿病(DM)的发病有关,如肌肉、外周血中的BMAL1基因,肝脏、胰腺中的CLOCK、BMAL1基因,下丘脑视交叉上核中的CLOCK、BMAL1、Per、Cry基因等。这些生物钟基因表达异常可引起葡萄糖代谢紊乱、葡萄糖耐受性降低、胰岛素分泌障碍、胰岛素抵抗,最终导致DM的发病。
[Abstract]:The clock gene includes the peripheral clock gene and the central clock gene.At present, the biological clock genes are mainly aromatics receptor nuclear translocation protein-like gene (BMAL1), clock gene (CLOCK1), cryptochrome gene 1 (Cry1), cryptochrome gene 2 (Cry2), cycle gene (1), cycle gene (2), cycle gene (2), cycle gene (3), and so on.It has been found that the changes of the expression of peripheral and central clock genes are related to the pathogenesis of DM, such as the BMAL1 gene in muscle, peripheral blood, the BMAL1 gene in liver and pancreas, and the CLOCK-BMAL1 / Per-Cry gene in supraoptic nucleus of hypothalamus.The abnormal expression of these circadian clock genes may cause glucose metabolism disorder, glucose tolerance decrease, insulin secretion disturbance, insulin resistance, and eventually lead to the pathogenesis of DM.
