LID - BSR20190227 [pii] LID - 10.1042/BSR20190227 [doi] AB - Laryngeal squamous cell carcinoma (LSCC) is a common aggressive head and neck cancer. Circular RNAs (circRNAs) are implicated in numerous physiological and pathological processes, including tumorigenesis. The present study aimed to investigate the expression profile and biological role of circMYLK in LSCC. We found that circMYLK was highly expressed in LSCC tissues and cell lines. circMYLK overexpression promoted LSCC cell proliferation and G(1)/S cell cycle transition; whereas circMYLK knockdown had the contrary effects. Mechanistically, circMYLK can serve as a competing endogenous RNA for miR-195 to increase cyclin D1 expression in LSCC, and rescue experiments further showed that restoration of miR-195 could block the oncogenic role of circMYLK in LSCC. In conclusion, our findings indicate that the circMYLK/miR-195/cyclin D1 regulatory axis could affect the proliferation and cell cycle progression of LSCC cells, and may provide a novel therapeutic target for the treatment of LSCC.
