MicroRNA-585 suppresses tumor proliferation and migration in gastric cancer by directly targeting MAPK1.

Increasing evidence reveals that microRNA contributes to the development and progression of gastric cancer (GC), but the roles of miR-585 in GC remain unclear. In this study, we confirmed that miR-585 was down-regulated in GC tissues and cell lines and that miR-585 expression was related to extent of invasion, TNM stage, lymph node invasion and poor prognosis. Our results showed that miR-585 inhibits the proliferation and migration of GC, and MAPK1 is a direct and functional target of miR-585. Our study sheds light on the role of miR-585 as a suppressor for tumor growth and metastasis and raises the intriguing possibility that miR-585 may serve as a new potential marker for monitoring and treating GC.
