Research Abstract

We compared miRNA expression levels in uterine papillary serous carcinoma (UPSC)with the levels in endometrial endometrioid adenocarcinoma (EEC)and normal endometria. Eight miRNAs were identified as having aberrant down-regulation specific to UPSC with miR-34b being most pronounced. Ectopic expression of miR-34b inhibited cell growth, migration, and most notably invasion. These effects are likely mediated by the downstream target of miR-34b, the proto-oncogene MET, a known prognostic factor in endometrial carcinomas. The expression of MET was reduced following the restoration of miR-34b in cell lines. In summary, our data suggest that miR-34b plays a role in the molecular pathogenesis of ESC.
