ZNF503 antisense RNA 1 (ZNF503-AS1) is a newly identified long non-coding RNA (lncRNA) that regulates retinal pigment epithelium differentiation. To study its role in diabetic retinopathy, we performed RT-qPCR to measure plasma ZNF503-AS1 levels of 298 diabetic patients immediately after the diagnosis, during the follow-up, and at the end of follow-up. Plasma lncRNA ZNF503-AS1 expression in 96 healthy participants was also detected by RT-qPCR. Transforming growth factor beta 1 (TGF-β1) expression after ZNF503-AS1 overexpression was detected by Western blot. Cell proliferation and apoptosis were detected by cell proliferation and apoptosis assays, respectively. We found that ZNF503-AS1 was not differentially expressed in healthy participants and diabetic patients. High plasma lncRNA ZNF503-AS1 level was correlated with a high incidence of diabetic retinopathy. Plasma lncRNA ZNF503-AS1 level was higher in patients with diabetic retinopathy than in patients with other complications (p < 0.05). ZNF503-AS1 overexpression inhibited proliferation, promoted cell apoptosis, and upregulated TGF-β1 expression (p < 0.05). We concluded that ZNF503-AS1 might participate in diabetic retinopathy by activating TGF-β signaling.
锌指蛋白 503 反义 RNA1(ZNF503-AS1)是一种新鉴定的长非编码 RNA(lncRNA),可调节视网膜色素上皮细胞分化。为了研究其在糖尿病视网膜病变中的作用,我们通过 RT-qPCR 测量了 298 名糖尿病患者在诊断后、随访期间和随访结束时的血浆 ZNF503-AS1 水平,并检测了 96 名健康参与者的血浆 lncRNA ZNF503-AS1 表达。通过 Western blot 检测 ZNF503-AS1 过表达后转化生长因子β1(TGF-β1)的表达。通过细胞增殖和凋亡检测分别检测细胞增殖和凋亡。我们发现健康参与者和糖尿病患者之间 ZNF503-AS1 的表达没有差异。高血浆 lncRNA ZNF503-AS1 水平与糖尿病视网膜病变的高发生率相关。糖尿病视网膜病变患者的血浆 lncRNA ZNF503-AS1 水平高于其他并发症患者(p<0.05)。ZNF503-AS1 过表达抑制增殖,促进细胞凋亡,并上调 TGF-β1 表达(p<0.05)。我们得出结论,ZNF503-AS1 可能通过激活 TGF-β 信号通路参与糖尿病视网膜病变。
