摘要: 目的 本研究旨在明确miR-532-3p/SERPINE1在结肠腺癌中的具体调控机制。方法 利用TCGA数据库筛选差异表达的mRNA,随后通过mirDIP、miRWalk数据库分析并确定上游调控基因miRNA。GSEA数据库进行富集通路的分析。实时荧光定量聚合酶链式反应(Real-time quantitative PCR,qRT-PCR)、细胞计数试剂盒(Cell Counting Kit-8,CCK-8)实验、克隆形成实验、划痕愈合、Transwell、蛋白质免疫印迹(Western blot,WB)研究SERPINE1及上游基因对结肠腺癌增殖、迁移、侵袭的调控机制。结果 SERPINE1在结肠腺癌细胞和组织中显著高表达,而miR-532-3p呈显著低表达。SERPINE1与结肠腺癌患者的预后不良有关,能促进结肠腺癌细胞增殖、迁移和侵袭。SERPINE1显著富集在细胞外基质受体互作通路。miR-532-3p靶向负调控SERPINE1的表达,回复实验表明miR-532-3p/SERPINE1调控细胞外基质受体互作通路影响结肠腺癌细胞的恶性进展。结论 miR-532-3p作为SERPINE1的上游调控基因,通过调控细胞外基质受体互作通路抑制结肠腺癌细胞增殖、迁移和侵袭。

Abstract: Objective SERPINE1 is associated with poor prognosis of many cancers and plays an important role in tumor metastasis. This study aims to clarify the specific regulatory mechanism of miR-532-3p/SERPINE1 in colon adenocarcinoma. Methods TCGA database was used to screen differentially expressed mRNAs, and then mirDIP and miRWalk databases were used to analyze and identify upstream regulatory gene miRNAs. GSEA database was used to the analysis of enrichment pathways. Real time quantitative polymerase chain reaction (qRT-PCR), CCK-8, cloning experiment, scratch healing, Transwell, Western blot (WB) to study the regulatory mechanism of SERPINE1 and its upstream genes on proliferation, migration and invasion of colon adenocarcinoma. Results SERPINE1 was significantly overexpressed in colon adenocarcinoma cells and tissues, while miR-532-3p was significantly overexpressed. SERPINE1 is related to the poor prognosis of colon adenocarcinoma patients and can promote the proliferation, migration and invasion of colon adenocarcinoma cells. SERPINE1 was significantly enriched in ECM RECEPTOR INTERACTION pathway. MiR-532-3p targets and negatively regulates the expression of SERPINE1. The reversion experiment shows that miR-532-3p/SERPINE1 regulates the ECM RECEPTOR INTERACTION pathway and affects the malignant progression of colon adenocarcinoma cells. Conclusion As the upstream regulatory gene of SERPINE1, miR-532-3p inhibits the proliferation, migration and invasion of colon adenocarcinoma cells by regulating ECM RECEPTOR INTERACTION. MiR-532-3p/SERPINE1 has the potential to become a new target for the treatment of colon adenocarcinoma.
