Abstract:
Circular RNAs (circRNAs) play a crucial role in the occurrence of several diseases including cancers. However, little is known about their role in Non-small cell lung cancer (NSCLC). In the present study, we found that hsa_circ_0075930 expression levels were significantly higher in NSCLC cell lines and tissues. The elevated hsa_circ_0075930 expression was correlated with tumor size (P = 0.001) and Lymph node metastasis (P = 0.038). Functional experiments showed knockdown of hsa_circ_0075930 followed by RNA silencing restrained cell proliferation and induced cell cycle arrest of NSCLC cells. In addition, hsa_circ_0075930 suppression impaired migration and invasion potential by reversing epithelial-to-mesenchymal transition (EMT). These results indicated that hsa_circ_0075930 upregulation may be a critical oncogene and potential new biomarker in NSCLC.
