چکیده انگلیسی
Astrocyte elevated gene-1 (AEG-1) is an oncogene overexpressed in multiple types of human cancers including ovarian cancer (OC). However, the underlying mechanism of AEG-1 up-regulation in OC is not well understood. In this study, we showed that miR-137 downregulated AEG-1 expression through interaction with its 3â² untranslated region (3â²UTR) and that miR-137 expression was inversely correlated with AEG-1 levels in OC specimens. Similar to the downregulation of AEG-1, overexpression of miR-137 in OC cell lines decreased in vitro cell growth, clonogenicity, and also induced G1 arrest. Importantly, miR-137 overexpression suppressed in vivo tumor growth in nude mice models. Furthermore, we found that restoring the AEG-1 (without the 3â²UTR) significantly rescued miR-137-induced cell growth inhibition and cell-cycle arrest. Taken together, these findings indicate that miR-137 functions as a tumor suppressor by inhibition of AEG-1. These molecules might be targets for prevention or treatment of OC.
