Our previous study showed that miR-23b was highly expressed in normal ovarian tissues than ovarian carcinoma tissues, and our predicted seed region in the 3′ untranslated regions (3′ UTR) of CCNG1 revealed that it’s a target of miR-23b, thus we investigated the involvement of CCNG1 and miR-23b in ovarian cancer for the first time. Here, CCNG1 is linked to ovarian carcinoma.
