摘要糖尿病视网膜病变(DR)发病机制复杂.长链非编码RNA(lncRNA)中INK4基因座中反义非编码RNA(ANRIL)与细胞增生、分化及个体发育过程密切相关,在视网膜血管内皮细胞的异常增生中起重要作用,是DR发病机制研究中的新领域.现有研究发现,ANRIL可能通过核因子-κB、ROS/聚腺苷二磷酸核糖聚合酶信号通路以及与p300、miR-200b、EZH2协同调节VEGF在DR中的表达和功能,发挥其在DR发生发展中的作用.特异性阻断ANRIL及其相关通路,可能成为未来DR临床治疗中的新靶点.

abstractsThe pathogenesis of diabetic retinopathy (DR) is complex.Antisense non-coding RNA (ANRIL) in the INK4 locus in long-chain non-coding RNA (lncRNA) is closely related to cell proliferation,differentiation,and individual development.It plays an important role in the dysplasia of retinal vascular endothelial cells and is a new field in the study of the pathogenesis of DR.According to the researches at present,ANRIL may plays its role in the occurrence and development of DR through the signal pathway of nuclear factor-κB and ROS/polyadenylation diphosphate ribose polymerase,and interact with p300,miR-200b,and EZH2 to regulating the expression and function of VEGF.Specific blocking ANRIL and its related pathwaysmay become a new target in the treatment of DR.
