Abstract/Description: We previously created two PER2::LUCIFERASE (PER2::LUC) circadian reporter knockin mice that differ only in the 3'-UTR region: , which retains the endogenous 3'-UTR and , where the endogenous 3'-UTR was replaced by an SV40 late poly(A) signal. To delineate the in vivo functions of 3'-UTR, we analyzed circadian rhythms of mice. Interestingly, mice displayed more than threefold stronger amplitude in bioluminescence rhythms than mice, and also exhibited lengthened free-running periods (∼24.0 h), greater phase delays following light pulse, and enhanced temperature compensation relative to Analysis of the 3'-UTR sequence revealed that miR-24, and to a lesser degree miR-30, suppressed PER2 protein translation, and the reversal of this inhibition in augmented PER2::LUC protein level and oscillatory amplitude. Interestingly, mRNA and protein oscillatory amplitude as well as CRY1 protein oscillation were increased in mice, suggesting rhythmic overexpression of PER2 enhances expression of and other core clock genes. Together, these studies provide important mechanistic insights into the regulatory roles of 3'-UTR, miR-24, and PER2 in expression and core clock function.
