PG - 1579-1589 LID - 10.2217/fon-2018-0058 [doi] AB - AIM: In this study, we investigated the role of Y-box binding protein-1 (YB-1), c-Myb and miR-155 in human laryngeal squamous cell carcinoma (LSCC) progression. MATERIALS & METHODS: Quantitative real-time PCR, western blot, MTT and Transwell were conducted to determine the expression and function of YB-1/miR-155 pathway. Univariate and multivariate analyses were used to determine the prognostic factors. RESULTS: Expression of YB-1, c-Myb and miR-155 was higher in LSCC tissues. YB-1 promoted proliferation, invasiveness and migration of Hep-2 cells in vitro. Patients with higher YB-1 correlated with advanced T stage, poor differentiation and cervical metastasis. LSCC patients with high YB-1 expression showed poor overall survival. CONCLUSION: YB-1 promotes LSCC progression by increasing miR-155 levels via c-Myb and acts as a prognostic factor.
