Lung cancer remains a leading cause of cancer-associated mortality worldwide, and non-small lung cancer (NSCLC) is responsible for over 80 % of lung cancer-related deaths. Identifying novel molecular biomarker that can inhibit the progression of lung cancer will facilitate the development of new treatment strategies. Herein, we demonstrated that miR-541-3p is a tumor-suppressor microRNA (miRNA) in NSCLC progression. We found that expression of miR-541-3p was decreased obviously in NSCLC tissues and plasma. Down-regulation of miR-541-3p was associated with TNM stage and postoperative survival. Overexpression of miR-541-3p inhibited the growth and metastasis of NSCLC cells. The TGIF2 was a direct target of miR-541-3p and promoted the growth and metastasis of NSCLC cells. Further study showed that TGIF2 could reverse the inhibitory effect of miR-541-3p on growth and metastasis of NSCLC cells. Taken together, our data highlight the pivotal role of miR-541-3p in the progression of NSCLC. Thus, miR-541-3p may be a potential prognostic marker and of treatment relevance for NSCLC progression intervention.
