摘要: 目的:旨在探讨LINC00460 在结直肠癌中的作用机制及其对细胞增殖、迁移和侵袭能力的影响。方法:通过对TCGA
数据库中结直肠癌患者组织样本进行lncRNA-miRNA-mRNA的竞争性内源RNA调控网络分析,并采用细胞培养、慢病毒转
染、CCK-8试剂盒检测、划痕试验、Transwell侵袭实验以及RT-PCR和qPCR等技术进行体外实验研究。结果:LINC00460 在
结直肠癌组织中呈显著高表达,且其表达与miR143 呈负相关,与COL1A1 mRNA呈正相关。沉默LINC00460 表达可显著降
低结直肠癌细胞的增殖、迁移和侵袭能力,而过表达LINC00460 则可显著提高正常结肠上皮细胞的增殖、迁移和侵袭能力。
结论:LINC00460 可能通过靶向竞争性抑制miR143,促进COL1A1 mRNA表达,从而促进结直肠癌细胞的增殖、迁移和侵袭,有
望成为结直肠癌治疗的潜在靶点。

Abstract: Objective: To investigate the role of LINC00460 in the mechanism of colorectal cancer and its impact on cell proliferation,
migration, and invasion capabilities. Methods: The competitive endogenous RNA regulatory network of lncRNA-miRNA-mRNA in
colorectal cancer patient tissue samples from the TCGA database was analyzed. In vitro experimental studies were conducted using
cell culture, lentiviral transfection, CCK-8 kit detection, scratch assay, Transwell invasion assay, as well as RT-PCR and qPCR
techniques. Results: LINC00460 was significantly upregulated in colorectal cancer tissues, with its expression negatively correlated
with miR143 and positively correlated with COL1A1 mRNA. Silencing LINC00460 expression significantly decreased the
proliferation, migration, and invasion of colorectal cancer cells, whereas LINC00460 overexpression significantly enhanced the
proliferation, migration, and invasion of normal colonic epithelial cells. Conclusion: LINC00460 may promote the proliferation,
migration, and invasion of colorectal cancer cells by competitively inhibiting miR143 (as a target) and upregulating COL1A1 mRNA
expression, and thus may serve as a potential therapeutic target for colorectal cancer.

Key words: colorectal cancer, LINC00460, miR143, COL1A1 mRNA
