Myotubularin-related protein 14 (MTMR14) is a member of the myotubularin (MTM)-related protein family and plays a key role in cardiomyopathy and autophagy. However, its potential implication in human cancer is unclear. In this study, we have investigated the expression profile of MTMR14 and its functional impact in liver cancer for the first time. Expression analysis by quantitative real-time polymerase chain reaction (qRT-PCR) and immunohistochemistry demonstrated that MTMR14 expression is obviously overexpressed in liver cancer, and positively correlated with clinical stage. A loss-of-function study showed that knockdown of MTMR14 promotes cell apoptosis and inhibits cell migration. MTMR14 knockdown also inhibits tumor migration in vivo in liver cancer peritoneal implantation nude mouse model. A molecular mechanistic study by western blot showed that Knockdown MTMR14 causes downregulation of N-cadherin and E-cadherin, and promotes the cleavage and activation of caspase12, caspase9 and caspase3, but excluding caspase8. These results suggest that MTMR14 affects cell migration through N-cadherin and E-cadherin. Additionally, MTMR14 affects cell apoptosis through mitochondrial pathway but not the death receptor pathway. Herein, our results indicate MTMR14 could have an oncogenic role in human liver cancer and thus demonstrates its potential as a target for the diagnosis and/or treatment of liver cancer.
