摘要

目的:探讨circ_0010729对高糖诱导的肾小球系膜细胞损伤的影响。方法:将人肾小球系膜细胞HMCL分为对照组、高糖(high glucose,HG)组、HG+si-NC组、HG+si-circ_0010729组、HG+miR-NC组、HG+miR-654-3p组、HG+si-circ_0010729+anti-miR-NC组、HG+si-circ_0010729+anti-miR-654-3p组。Real-time PCR检测circ_0010729和miR-654-3p的表达水平;流式细胞术检测细胞凋亡;ELISA检测白细胞介素-6(interleukin-6,IL-6)、肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)水平;双荧光素酶报告实验验证circ_0010729和miR-654-3p的靶向关系。结果:与对照组比较,HG组circ_0010729表达水平升高,miR-654-3p表达水平降低,细胞凋亡率升高,TNF-α、IL-6水平升高(P<0.05)。抑制circ_0010729表达或过表达miR-654-3p后,高糖诱导的人肾小球系膜细胞中细胞凋亡率降低,TNF-α、IL-6水平降低(P<0.05)。circ_0010729靶向调控miR-654-3p;干扰miR-654-3p表达逆转了抑制circ_0010729表达对高糖诱导的人肾小球系膜细胞凋亡及炎症反应的作用。结论:抑制circ_0010729表达可能通过靶向上调miR-654-3p表达抑制高糖诱导的肾小球系膜细胞凋亡及炎症反应。

Abstract

Objective: To investigate the effect of circ_0010729 on high glucose-induced mesangial cell injury. Methods: Human glomerular mesangial cells HMCL were divided into a control group, a high glucose (HG) group, a HG + miR-NC group, a HG + miR-654-3p group, a HG + si-NC group, a HG+si-circ_0010729 group, a HG + si-circ_0010729 + anti-miR-NC group, and a HG + si-circ_0010729 + anti-miR-654-3p group. Real-time PCR was performed to detect the expression levels of miR-654-3p and circ_0010729; flow cytometry was performed to detect the apoptosis of glomerular mesangial cells; ELISA was performed to detect interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) levels; dual luciferase report experiment was used to verify the targeting relationship between circ_0010729 and miR-654-3p. Results: Compared with the control group, the circ_0010729 expression was increased, the miR-654-3p expression was decreased, the apoptosis rate was increased, the TNF-α and IL-6 levels were increased in the HG group (P<0.05). After inhibiting the expression of circ_0010729 or overexpression of miR-654-3p, the apoptosis rate of human glomerular mesangial cells induced by high glucose was decreased, the levels of TNF-α and IL-6 were decreased (P<0.05). circ_0010729 targeted and regulated miR-654-3p; interfering with the expression of miR-654-3p reversed the effect of inhibiting the expression of circ_0010729 on the apoptosis and inflammation of human glomerular mesangial cells induced by high glucose. Conclusion: Inhibiting the expression of circ_0010729 may inhibit the apoptosis and inflammation of glomerular mesangial cells induced by high glucose through targeting up-regulation of miR-654-3p expression.
