摘要
Increasing evidence suggests that microRNAs (miRNAs) play a critical role in tumorigenesis. Decreased expression of miR-382 has been observed in various types of cancers. However, the biological function of miRNA-382 in ovarian cancer is still largely unknown. Here, we found miR-382 was downregulated in human ovarian cancer tissues and cell lines. miR-382 inhibited ovarian cancer cell proliferation, migration, invasion and the epithelial-mesenchymal transition (EMT). Furthermore, we identified receptor tyrosine kinase orphan receptor 1 (ROR1) as a target of miR-382, and miR-382 rescued the promotion effect of ROR1 on migration, invasion and EMT process in SKOV3 and COV434 cells. Collectively, these findings revealed that miR-382 inhibits migration and invision by targeting ROR1 through regulating EMT in ovarian cancer, and might serve as a tumor suppressor in ovarian cancer.
