Abstract

The role of microRNA (miR)‑1301‑3p has been investigated in breast cancer and colorectal cancer. Dysregulation of miR‑1301‑3p expression in non‑small cell lung cancer (NSCLC) is speculated to be associated with tumor progression, which was systemically investigated in the present study. Reverse transcription‑quantitative PCR analysis was performed to detect miR‑1301‑3p expression in 124 paired tissue samples and cultured cell lines. The results demonstrated that miR‑1301‑3p expression was regulated by transfection with miR‑1301‑3p mimic or inhibitor, and the proliferation, migration and invasion of the transfected cells were assessed via the Cell Counting Kit‑8 and Transwell assays. In addition, miR‑1301‑3p expression was significantly upregulated in NSCLC tissues and cells compared with normal tissues and normal cells, respectively. Notably, upregulated miR‑1301‑3p expression in NSCLC tissues was significantly associated with the TNM stage, lymph node metastasis and poor prognosis of patients with NSCLC. Furthermore, upregulated miR‑1301‑3p expression in NSCLC cells promoted cell proliferation, migration and invasion, the effects of which were reversed following miR‑1301‑3p knockdown. Thy‑1 was identified as a direct target of miR‑1301‑3p, which serves as a tumor promoter in the progression of NSCLC. Taken together, the results of the present study suggest that upregulated miR‑1301‑3p expression in NSCLC acts as an independent prognostic factor and a tumor promoter by targeting thy‑1, thus provides a potential therapeutic target for NSCLC.
