CircRNA 001306 enhances hepatocellular carcinoma growth by up-regulating CDK16 expression via sponging miR-584-5p.

ABSTRACT: Circular RNAs (circRNAs) have been demonstrated to play important roles in cancer progress. However, the roles in hepatocellular carcinoma (HCC) are still unclear. Here, we found has_circRNA_001306 (circ_1306) was up-regulated in HCC tissues and cell lines. Knockdown the expression circ_1306 significantly suppressed HCC cell proliferation and induced the cell apoptosis in vitro and in vivo. Furthermore, we identified circ_1306 could up-regulate the expression of CDK16 by sponging miR-584-5p. The expression of miR-584-5p was decreased, and the expression of CDK16 was increased in HCC tissues and cell lines. Meanwhile, either knockdown of miR-584-5p or overexpression of CDK16 could suppress the HCC cell proliferation. In vivo, overexpression of miR-584-5p or knockdown of circ_1306 could inhibit the expression of CDK16, and suppress tumour growth. Altogether, our findings suggested that circ_1306 could promoter HCC progress by miR-584-5p/CDK16 axis, which provided a novel marker for HCC diagnosis and treatment.

Project description:BackgroundNon-small cell lung carcinomas (NSCLC) are prevalent, lethal cancers with especially grim prospects due to late-stage detection and chemoresistance. Circular RNAs (circRNAs) are non-coding RNAs that participate in tumor development. However, the role of circRNAs in NSCLC is not well known. This study investigated the role of one circRNA - circPTPRA- in NSCLC and characterized its molecular mechanism of action.MethodscircPTPRA expression was analyzed in human NSCLC tumors and matched healthy lung tissue. We performed functional characterization in NSCLC cell lines and a mouse xenograft model of NSCLC to elucidate the molecular role of circPTPRA in epithelial-mesenchymal transitioning (EMT). We also assessed the regulatory action of circPTPRA on the microRNA miR-96-5p and its target the tumor suppressor Ras association domain-containing protein 8 (RASSF8).FindingscircPTPRA was significantly downregulated in NSCLC tumors relative to matched healthy lung tissue. Lower circPTPRA levels correlated with metastasis and inferior survival outcomes in NSCLC patients. circPTPRA suppressed EMT in NSCLC cell lines and reduced metastasis in the murine xenograft model by sequestering miR-96-5p and upregulating RASSF8. Correlation analyses in patient-derived NSCLC tumor specimens supported the involvement of the circPTPRA/miR-96-5p/RASSF8/E-cadherin axis dysregulation in NSCLC tumor progression.InterpretationcircPTPRA suppresses EMT and metastasis of NSCLC cell lines by sponging miR-96-5p, which upregulates the downstream tumor suppressor RASSF8. The circPTPRA/miR-96-5p/RASSF8/E-cadherin axis can be leveraged as a potential treatment avenue in NSCLC.
