文章摘要:circABCA3敲低通过靶向miR-671-5p/PCSK9轴缓解缺氧诱导的人心脏微血管内皮细胞功能障碍。
内皮细胞功能障碍是急性心肌梗死(AMI)发展的重要阶段之一。然而,circABCA3 (hsa_circ_0037516)是否通过调节内皮细胞功能障碍介导AMI的发展尚不清楚。使用GEO数据库(GSE169594和GSE160717)筛选差异表达的环状rna。采用缺氧诱导的人心脏微血管内皮细胞(HCMECs)模拟AMI细胞模型。采用实时荧光定量PCR检测circABCA3、microRNA (miR)-671-5p、蛋白转化酶subtilisin/ keexin type 9 (PCSK9)的表达。采用细胞计数试剂盒8法、EdU法、transwell法、伤口愈合法、成管法和流式细胞术检测细胞增殖、迁移、血管生成和凋亡。采用双荧光素酶报告基因试验和RIP试验验证RNA相互作用。western blot检测PCSK9蛋白及凋亡相关标志物的表达情况。根据GEO数据库筛选,circABCA3是AMI患者血液样本中高表达的circRNA。circABCA3在AMI患者和缺氧诱导的HCMECs中过表达。在缺氧诱导的HCMECs中,circABCA3的沉默增强了增殖、迁移和血管生成,并抑制了细胞凋亡。circABCA3海绵miR-671-5p正向调节PCSK9的表达。miR-671-5p抑制剂或PCSK9过表达推翻了circABCA3敲低对缺氧诱导的HCMEC功能障碍的调节。circABCA3可能是缓解AMI过程的潜在靶点,其中敲低通过调节miR-671-5p/PCSK9轴缓解缺氧诱导的HCMEC功能障碍。

期刊介绍: Cell Stress and Chaperones is an integrative journal that bridges the gap between laboratory model systems and natural populations. The journal captures the eclectic spirit of the cellular stress response field in a single, concentrated source of current information. Major emphasis is placed on the effects of climate change on individual species in the natural environment and their capacity to adapt. This emphasis expands our focus on stress biology and medicine by linking climate change effects to research on cellular stress responses of animals, micro-organisms and plants.
