Abstract

An increasing number of studies have demonstrated that microRNAs (miRNAs/miRs) are involved in cancer progression. In 2010, an estimated 1,500,000 patients suffered mortality from lung cancer (LC) worldwide, and ~80% of LC patients were diagnosed with non‑small‑cell lung cancer (NSCLC). miR‑584‑5p was reported to be a potential biomarker in the diagnosis of LC; in addition, miR‑584 was recently observed to suppress the progression of thyroid carcinoma, glioma and gastric cancer. However, the specific function of miR‑584‑5p in NSCLC remains unclear. In the present study, miR‑584‑5p was decreased in the tumor tissues of NSCLC patients. Furthermore, miR‑584‑5p markedly inhibited the migration and invasion of NSCLC cells. The direct regulatory association between miR‑584‑5p and matrix metalloproteinase (MMP)‑14 was verified by a luciferase reporter gene assay. Furthermore, the results indicated that miR‑584‑5p inhibited the expression of MMP‑14 at the protein and mRNA levels. miR‑584‑5p also inhibited the expression of MMP‑4 and Slug, which are involved in tumor invasion and metastasis. Taken together, these results indicated that the miR‑584‑5p/MMP‑14 axis may serve as an anticancer target in the treatment of NSCLC patients.
