Low Expression LncRNA TUBA4B is a Poor Predictor of Prognosis and Regulates Cell Proliferation in Non-Small Cell Lung Cancer

Abstract

We aimed to unveil the clinical roles and biological function of lncRNA TUBA4B in on-small cell lung cancer (NSCLC). The relative expression level of TUBA4B was estimated by qPCR in 114 pairs of NSCLC and NT samples and the relation of TUBA4B to clinical data of NSCLC patients was analyzed. We found TUBA4B was lower expressed in NSCLC and five cell lines. The lower expression of TUBA4B was remarkably correlated with advanced TNM stage and lymph node metastasis and served as a predictor for overall survival of NSCLC. After overexpression of TUBA4B, cell proliferation ability of A549 and NCI-H1299 remarkably decreased. Our study ascertained low expression TUBA4B in NSCLC tissue, cell lines and is a poor predictor for prognosis and can regulate cell proliferation in NSCLC.
