Abstract

The present study aimed to explore whether and how microRNA‑5580‑3p (miR‑5580‑3p) affected oral cancer (OC) cell phenotypes via regulation of laminin subunit γ2 (LAMC2). Bioinformatics analysis was used to identify miR‑5580‑3p/LAMC2, a novel interactome that, to the best of our knowledge, has not been studied previously in OC. In the present study, the expression levels of miR‑5580‑3p and LAMC2 were detected by reverse transcription‑quantitative PCR, while the protein expression levels of LAMC2 were identified using western blotting. To determine the effects of miR‑5580‑3p and LAMC2 in OC, a number of experiments, including Cell Counting Kit‑8, 5‑bromo‑2'‑deoxyuridine cell proliferation and wound healing migration assays, were performed using OC SCC‑4 and Cal‑27 cell lines. Additionally, luciferase reporter assays were employed to examine the interaction between miR‑5580‑3p and LAMC2 mRNA. The results demonstrated that miR‑5580‑3p expression was downregulated, while LAMC2 expression was upregulated in OC tissues and cell lines. In addition to the observation that miR‑5580‑3p promoted the malignant phenotypes of OC, it was also revealed that miR‑5580‑3p inhibited OC cell viability, proliferation and migration by suppressing LAMC2. Therefore, the present study suggested that miR‑5580‑3p and LAMC2 may be potential biomarkers and therapeutic targets for OC diagnosis and therapies in the future.
