... absence of afunctional SCN [27]. Therefore, it would be interesting to determine the exact role of miR-192 ⁄ 194 in thesetissues. Together, the identification of inhibitorymiRNAs for the Per genes ... mode of repressionleads to the cycling of BMAL1 mRNA levels in ananti-phase fashion to that of the CCGs. When the other negative regulators of BMAL1, the Per and Cryproteins, are at their ... role in both of these tissues [25,26].Interestingly, both of these tissues have been suggested to be the only ones that are able to maintain circadianrhythms of clock gene expression in the...
