Inhibition of miR-92b suppresses nonsmall cell lung cancer cells growth and motility by targeting RECK

Abstract

microRNAs play critical roles in the progression and metastasis of nonsmall cell lung cancer (NSCLC). miR-92b acts as an oncogene in some malignancies; however, its role in NSCLC remains poorly understood. Here, we found that miR-92b was significantly increased in human NSCLC tissues and cell lines. Inhibition of miR-92b remarkably suppressed cell proliferation, migration, and invasion of NSCLC cells. Reversion-inducing-cysteine-rich protein with kazal motifs (RECK) was identified to be a target of miR-92b. Expression of miR-92b was negatively correlated with RECK in NSCLC tissues. Collectively, miR-92b might promote NSCLC cell growth and motility partially by inhibiting RECK.
