miR‑221‑3p promotes the cell growth of non‑small cell lung cancer by targeting p27

Emerging evidence suggests the critical function of microRNAs in regulating the growth of cancer cells. In the present study, it was demonstrated that miR‑221‑3p was overexpressed in non‑small cell lung cancer (NSCLC) tissues and cell lines compared with that noted in the normal controls. Downregulation of miR‑221‑3p suppressed the proliferation, colony formation and invasion of NSCLC cells. To further understand the molecular mechanisms...
