Circular RNAs (circRNAs) has emerged as vital regulator involved in various diseases. In this study, we identified and investigated the potential circRNAs involved in gestational diabetes mellitus (GDM).
High-throughput sequencing was used to collect the plasma circRNAs expression profiles of GDM patients. Quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR) was used to measure the expressions of circ_0008285 and circ_0001173 in the plasma specimens. The Pearson's correlation test was employed to assess the correlation between 2 circRNAs expression and the clinicopathologic data. Two circRNAs expression was verified in high glucose (HG)-induced HTR-8/SVneo cells. MTS, transwell assay was used to evaluate the effects of circ_0008285 expression on HG-induced HTR-8/SVneo cells. The network of circ_0008285 was constructed using cytocape.
In GDM patients, the expression of circ_0008285 was significantly upregulated, while that of circ_0001173 was decreased. Circ_0008285 was significantly correlated with the total cholesterol and LDL-C levels. Circ_0001173 was significantly correlated with glycated hemoglobin. HG promoted the proliferation, invasion, and migration in HTR-8/SVneo cells, while the knockdown of circ_0008285 exerted reverse effects. In addition, network construction exhibited that circ_0008285 had 45 miRNA binding sites, which correlated with 444 mRNA.
circ_0008285 plays an important role and provides a clue for the usage of therapeutic targets in the development of GDM.
环状 RNA(circRNAs)已成为参与多种疾病的重要调控因子。在这项研究中,我们鉴定并研究了与妊娠期糖尿病(GDM)相关的潜在环状 RNA。
采用高通量测序技术收集 GDM 患者血浆环状 RNA 表达谱。采用实时定量逆转录聚合酶链反应(qRT-PCR)测量血浆标本中 circ_0008285 和 circ_0001173 的表达。采用 Pearson 相关检验评估 2 个 circRNA 表达与临床病理数据之间的相关性。在高糖(HG)诱导的 HTR-8/SVneo 细胞中验证 2 个 circRNAs 的表达。采用 MTS 和 Transwell 实验评估 circ_0008285 表达对 HG 诱导的 HTR-8/SVneo 细胞的影响。采用 Cytocape 构建 circ_0008285 网络。
在 GDM 患者中,circ_0008285 的表达显著上调,而 circ_0001173 的表达则降低。circ_0008285 与总胆固醇和 LDL-C 水平显著相关。circ_0001173 与糖化血红蛋白显著相关。HG 促进 HTR-8/SVneo 细胞的增殖、侵袭和迁移,而 circ_0008285 的敲低则产生相反的效果。此外,网络构建表明 circ_0008285 有 45 个 miRNA 结合位点,与 444 个 mRNA 相关。
circ_0008285 发挥着重要作用,并为 GDM 发展中治疗靶点的应用提供了线索。
