Description
Abstract
Background. Emerging studies have demonstrated that microRNAs (miRNAs) play crucial roles in the carcinogenesis of many developing human tumors. However, the clinical significance and biological function of microRNA-3648 (miR-3648) in non-small cell lung cancer (NSCLC) have been largely undefined. Methods. The expression of miR-3648 and the mRNA of adenomatous polyposis coli 2 (APC2) in NSCLC tissues and cell lines were analyzed using quantitative real-time RT-PCR. The prognostic value of miR-3648 and APC2 was examined using the KaplanMeier method and Cox regression analyses. Experiments using NSCLC cells were conducted to explore the influences of miR-3648 on tumor cell proliferation, migration and invasion. Result. Increased expression of miR-3648 was observed in NSCLC tissues and cell lines compared with the corresponding controls (all P<0.05). miR-3648 expression was associated with the differentiation, lymph node metastasis and TNM stage (all P<0.05) of NSCLC patients, and high expression of miR-3648 was associated with poor overall survival rate. NSCLC cell proliferation, migration and invasion were significantly enhanced by miR-3648 overexpression. The further luciferase reporter assay and expression results showed that the decreased APC2 might also be a prognostic biomarker, and served as a target of miR-3648 in NSCLC. Conclusion. The findings from the present study indicate that the overexpression of miR-3648 serves as a useful biomarker for the prediction of prognosis in NSCLC, and promotes tumor cell proliferation, migration and invasion. APC2, as another prognosisrelated molecule, may be a target of miR-3648 in NSCLC.
