ABSTRACT The aim of our study was to investigate the effects of miR‐133a‐3p on human oral squamous cell carcinoma (OSCC) cells by regulating gene COL1A1. OSCC tissues, adjacent tongue epithelial tissues, the immortalized oral epithelial cell line HIOEC, and OSCC cell lines (CAL‐27, TCA‐8113, SCC‐4, SCC‐9, and SCC‐15) were used in this research. Quantitative real‐time PCR (RT‐qPCR) was employed to determine the expression of miR‐133a‐3p and COL1A1. Dual luciferase reporter gene assay and Western blot were applied to verify the binding relationship between miR‐133a‐3p and COL1A1. Functional assays were also conducted in this study, including CCK‐8 assay, colony formation assay, flow cytometry analysis as well as Transwell assay. MiR‐133a‐3p was found low‐expressed both in OSCC tissues and cells lines compared with normal tissues and cell line, respectively, whereas COL1A1 was just the opposite. The over‐expression of miR‐133a‐3p or the down‐regulation of COL1A1 suppressed the proliferation, invasion, and mitosis of OSCC cells, whereas simultaneous down‐regulation of miR‐133a‐3p and up‐regulation of COL1A1 led to no significant alteration of cell activities. MiR‐133a‐3p could inhibit the proliferation and migration of OSCC cells through directly targeting COL1A1 and reducing its expression. J. Cell. Biochem. 119: 338–346, 2018. © 2017 Wiley Periodicals, Inc. MiR‐133a‐3p was proved to target COL1A1 3′UTR directly. MiR‐133a‐3p inhibited CAL‐27 cell proliferation and invasion by directly suppressing COL1A1. MiR‐133a‐3p suppressed cell mitosis and promoted cell apoptosis by inhibiting COL1A1.
