Integration of Feeding Behaviour by the Liver Circadian Clock Reveals Network Dependency of Metabolic Rhythms [RNA-seq]

Project description:The mammalian circadian clock, expressed throughout the brain and body, controls daily metabolic homeostasis. Clock function in peripheral tissues is required, but not sufficient, for this task. Due to lack of specialized animal models, it is unclear how tissue clocks interact with extrinsic signals to drive molecular oscillations. Here, we present a model in which the interaction between feeding and the liver clock can be isolated in vivo by reconstituting Bmal1 exclusively in hepatocytes (Liver-RE) in otherwise clock-less mice. We found that the cooperative action of BMAL1 and the transcription factor CEBPB regulates daily liver metabolic transcriptional programs. Functionally, the liver clock and feeding rhythm are sufficient to drive temporal glucose homeostasis. By contrast, liver rhythms tied to redox and lipid metabolism required communication with the skeletal muscle clock, demonstrating peripheral clock cross-talk. Our results highlight how the inner workings of the clock system rely on communicating signals to maintain daily metabolism.

Integration of feeding behavior by the liver circadian clock reveals network dependency of metabolic rhythms.

Project description:The mammalian circadian clock, expressed throughout the brain and body, controls daily metabolic homeostasis. Clock function in peripheral tissues is required, but not sufficient, for this task. Because of the lack of specialized animal models, it is unclear how tissue clocks interact with extrinsic signals to drive molecular oscillations. Here, we isolated the interaction between feeding and the liver clock by reconstituting Bmal1 exclusively in hepatocytes (Liver-RE), in otherwise clock-less mice, and controlling timing of food intake. We found that the cooperative action of BMAL1 and the transcription factor CEBPB regulates daily liver metabolic transcriptional programs. Functionally, the liver clock and feeding rhythm are sufficient to drive temporal carbohydrate homeostasis. By contrast, liver rhythms tied to redox and lipid metabolism required communication with the skeletal muscle clock, demonstrating peripheral clock cross-talk. Our results highlight how the inner workings of the clock system rely on communicating signals to maintain daily metabolism.

Clock rescue in the brain restores 12- and 24- hour rhythms in the liver

Project description:Circadian profiling was performed in mouse livers from three different genotypes/treatments: Wildtype, Clock mutant, and brain-specific Clock rescue. Rescuing Clock specifically in the brain partially rescued robust circadian and harmonic rhythms. Samples were collected every 2 hours for 48 hours from 2-4 mice per time point; samples were pooled and analyzed using Affymetrix Mouse Exon arrays, analyzed at the gene level.

Circadian clock controls rhythms in ketogenesis by interfering with PPARa transcriptional network

Project description:Ketone bodies, intermediates in energy metabolism and signaling, have attracted significant attention due to their role in health and disease. We performed around the clock study on ketone bodies and ketogenesis with mice on different diets. We found that caloric restriction, a dietary intervention that improves metabolism and longevity, induced high amplitude circadian rhythms in blood βOHB. The blood βOHB rhythms resulted from rhythmic ketogenesis in the liver controlled by the interaction between the circadian clock and PPAR transcriptional networks. This interaction results in transcriptional reprogramming of in beta-oxidation and ketogenesis enzymes. The reprogramming is impaired in circadian clock mutant mice. The circadian clock gated ketogenesis contributes to the diet impact on health and longevity.
