背景醛糖还原酶(Aldosereductase,AR),作为山梨醇代谢通路(thepolyolpathway,PP)的限速酶,它的异常激活是导致糖尿病并发症的危险因素。先前的动物实验表明AR的抑制剂唑泊司他(zopolrestat)能显著预防糖尿病的并发症,而肾素-血管紧张素系统(therenin-angiotensinsystem/angiotensinII,RAS/AngII)控制水盐和血压平衡。但是,AR/PP与RAS/AngII之间是否存在相互作用并不清楚。在本论文中,我们进行了一系列的体内和体外实验研究,旨在揭示AR/PP与RAS/AngII相互作用的分子机制。 方法和结果我们发现...Background Aldose reductase (AR), the first and the rate-limiting enzyme of the polyol pathway (PP), is involved in diabetic complications. The use of AR inhibitors (ARI), zopolrestat, in preventing diabetic changes in animals strongly suggests that AR may play critical roles in the development of other diabetic complications. The renin-angiotensin system/angiotensin II (RAS/AngII) signaling...学位:理学博士院系专业:生命科学学院_细胞生物学学号:2162012015380
