Abstract

Objective: This study explored the effect of miR-26a-5p on cell proliferation, migration, and invasion in gastric cancer by targeting COL10A1.

Materials and methods: First, differentially expressed genes were identified from microarray GSE103236 data of human gastric cancer. Then, qRT-PCR was carried out to detect the expression levels of COL10A1 and miR-26a-5p in gastric cancer cells and normal cases. The CCK-8 method was used to test cell proliferation. The colony formation assay was performed for the examination of the cell colony-forming ability, and transwell was applied for the detection of cell migration and invasion. Subsequently, the targeted relationship between miR-26a-5p and COL10A1 was identified by bioinformatics methods and further verified by Dual-Luciferase assay. The rescue experiment was finally conducted to validate the miR-26a-5p-dependent mechanism on cell proliferation, migration, and invasion via targeting COL10A1.

Results: COL10A1 was found to be highly expressed in gastric cancer cells, while miR-26a-5p was poorly expressed. Silencing COL10A1 inhibited cell proliferation, migration, and invasion in gastric cancer. Besides, miR-26a-5p could function on gastric cancer cells by reducing COL10A1. As well, the rescue experiment suggested that the down-regulation of COL10A1 could reverse the inhibitory effect of miR-26a-5p on gastric cancer cells.

Conclusions: Collectively, miR-26a-5p can potentiate proliferation, migration, and invasion of gastric cancer cells by targeting COL10A1.
