Epub 2021 Jan 29. ABSTRACT MicroRNAs (miRNAs) play an important role in the occurrence and development of colorectal cancer (CRC). Evidence shows that miR-432-5p expression is decreased in various tumors and cancer cell lines. miR-432-5p can inhibit tumor invasion and metastasis, but its role in colorectal cancer is unclear. The present study demonstrated that miR-432-5p expression was decreased in colorectal cancer tissue and cell lines, and is negatively associated with invasion classification, lymph node metastasis and Tumor-Node-Metastasis stage. Kaplan-Meier survival analysis showed that low miR-432-5p expression was associated with a poor survival rate in patients with CRC. In addition, SW480 and HT-29 cells transfected with miR-432-5p mimics had decreased migration and invasion abilities, whereas miR-432-5p inhibitors had the opposite effect. The expression of C-X-C m otif chemokine ligand 5 (CXCL5), a direct target of miR-432-5p, was negatively associated with miR-432-5p expression. When CXCL5 was introduced into miR-432-5p mimic-transfected SW480 and HT-29 cells, miR-432-5p-mediated inhibition of CRC migration and invasion was reversed. Thus, the present results suggest that miR-432-5p can inhibit the migration and invasion of CRC cells by targeting CXCL5.
