Abstract
Colorectal cancer (CRC) is the third most common type of cancer worldwide. Recent studies have shown that lncRNAs play important roles in carcinogenesis. The aim of this study was to explore the role of lncRNA GAS5 in CRC. Real-time PCR was performed to investigate the expression of GAS5 in tumor tissues and corresponding non-tumor colorectal tissues from 66 patients with CRC. The lower expression of GAS5 was significantly correlated with large tumor size, low histological grade and advanced TNM stage. Multivariate analyses revealed that GAS5 expression served as an independent predictor for overall survival (P = 0.034). Further experiments revealed that overexpressed GAS5 significantly repressed the proliferation both in vitro and in vivo. In conclusion, our results suggest that GAS5, as a growth regulator, may serve as a candidate prognostic biomarker in human colorectal cancer.
