Circular RNAs (circRNAs), a group of non-coding RNAs, play an important role in cancer biology, and in the present study, we aimed to clarify the expression profiles and biological functions of circRNA circVANGL1 in non-small cell lung cancer (NSCLC). The results showed that circVANGL1 was overexpressed in human NSCLC tissues and cell lines. circVANGL1 expression was closely associated with tumor size, TNM stage and overall survival of NSCLC patients. Further loss-of-function analysis revealed that knockdown of circVANGL1 inhibited proliferation and induced apoptosis in NSCLC cell lines. The migration and invasion of NSCLC cells were also suppressed by circVANGL1 knockdown. In addition, we predicted that circVANGL1 might serve as a competing endogenous RNA (ceRNA), becoming a sink for miR-195, thereby modulating the expression of Bcl-2 in NSCLC cells. Rescue experiments demonstrated that miR-195 inhibitor abrogated the beneficial role of circVANGL1 knockdown in NSCLC cells. Taken together, we conclude that circVANGL1 functions as an oncogene to promote NSCLC progression partly through miR-195/Bcl-2 axis, which might be a novel therapeutic target for NSCLC patients.

Up-regulated circular RNA VANGL1 contributes to progression of non-small cell lung cancer through inhibition of miR-195 and activation of Bcl-2
