Abstract

The high mortality of colorectal cancer (CRC) is likely caused by early invasion and metastasis. The chemoresistance of tumor cells is the critical reason for treatment failure. The present study aimed to develop targeted solutions to overcome chemotherapy drug resistance in CRC. CCK‑8 assay was used to examine SW480 cell viability. SW480 cell apoptosis was examined using flow cytometry. The present study demonstrated that the expression of miR‑1271 was significantly decreased in CRC tumors and cell lines compared with control tissues. Furthermore, the expression of microRNA (miR)‑1271 was increased and decreased following the transfection of miR‑1271 mimics and an inhibitor, respectively. Furthermore, miR‑1271 regulated mammalian target of rapamycin (mTOR) expression by directly binding to the mTOR 3'‑untranslated region and the relative luciferase activity of mTOR was decreased following miR‑1271 overexpression. The results of the present study indicate that miR‑1271 may be a potential target for anti‑CRC therapy, particularly in the sensitivity of chemotherapeutic drugs. miR‑1271 may therefore enhance the sensitivity of CRC cells to chemotherapy drugs and provide a novel approach for the gene therapy of CRC.
