CCNJ and prostate carcinoma: CCNJ was found to be downstream of miR-205, and it has been linked to the G2/M cell cycle in prostate cancers.20 More interestingly, we have found that there are a couple of putative miR-205 binding sites in the 3′ untranslated region (3′UTR) of CCNJ as shown in Figure 4a.
