英文摘要
7. Project Summary/Abstract
Our previous studies identified the circadian clock component cryptochromes (CRY1 and CRY2)
as nutrient responsive transcriptional regulators by virtue of their susceptibility to
phosphorylation by AMP-activated protein kinase (AMPK). We have also described a function of
CRY1 and CRY2 as diurnally active repressors of the glucocorticoid receptor, a prototypical
member of a large family of transcriptional regulators known as nuclear hormone receptors
(NRs). NRs are broadly important in modulating metabolic physiology and one member of this
family, the so-called peroxisome proliferator activated receptor delta (PPARδ) has been
established as a critical driver of exercise capacity. We describe in our preliminary data here
that CRY1 and CRY2 can repress PPARδ and genetic deletion of Cry1 and Cry2 ubiquitously
and throughout development results in enhanced sprint exercise capacity. In the course of our
studies, we have generated unique tools and expertise that enable us to use biochemical,
genetic, molecular and physiological approaches to further elucidate the roles of CRY1 and
CRY2 in the regulation of PPARδ and of exercise physiology in the following specific aims: 1)
Does skeletal muscle drive enhanced exercise capacity in Cry1/2-deficient mice? 2) How does
AMPK-mediated CRY1 phosphorylation impact exercise? and 3) What is the impact of Cry1/2
deletion or mutation on skeletal muscle cellular metabolism? Advancing our functional
understanding of these interactions may highlight new therapeutic and regulatory strategies for
preventing and/or treating disease.
