Time-restricted feeding shifts the skin circadian clock and alters UVB-induced DNA damage

Project description:The epidermis is as a highly regenerative barrier protecting organisms from environmental insults, including ultraviolet radiation, the main cause of skin cancer and skin aging. Here we show that time-restricted feeding (RF) shifts the phase and alters the amplitude of the skin circadian clock and affects the expression of approximately 10% of the skin transcriptome. Furthermore, a strikingly large number of skin-expressed genes are acutely regulated by food intake. While the circadian clock is required for daily rhythms in DNA synthesis in epidermal stem cells, RF-induced shifts in clock phase do not alter the phase of DNA synthesis. However, both the expression of the key DNA repair gene Xpa, and the diurnal sensitivity to UVB-induced DNA damage, are altered by RF. Together our findings indicate an unexpected regulation of skin function by time of feeding and emphasize the important link between circadian rhythm, food intake, and skin health.

Circadian Proteomics Landscape of Mouse Livers Organized by Time-restricted Feeding: Proteomics

Project description:Meal timing is essential in synchronization of circadian rhythms in different organ systems through clock-dependent and -independent mechanisms. The liver is a critical metabolic organ whose circadian clock and transcriptome can be readily reset by meal timing. However, it remains largely unexplored how circadian rhythms in the liver are organized in time-restricted feeding that intervenes meal timing. Here, we applied data-independent acquisition proteomics to characterize circadian features associated with day/sleep- (DRF) and night/wake (NRF)-time restricted feeding in nocturnal female mice. The transcriptomics and metabolomics datasets are public (see www.circametdb.org.cn).

The effects of temporally restricted feeding on hepatic gene expression of Cry1, Cry2 double KO mice

Project description:Restricted feeding impacts the hepatic circadian clock of WT mice. Cry1, Cry2 double KO mice lack a circadian clock and are thus expected to show rhythmical gene expression in the liver. Imposing a temporally restricted feeding schedule on these mice shows how the hepatic circadian clock and rhythmic food intake regulate rhythmic transcription in parallel

Hepatic transcriptome by Next Generation Sequencing of WT and clock mutant mice fed a HFD ad libitum or time-restricted feeding.

Project description:Increased susceptibility of circadian clock mutant mice to metabolic diseases has led to the understanding that a molecular circadian clock is necessary for metabolic homeostasis. Circadian clock produces a daily rhythm in activity-rest and an associated rhythm in feeding-fasting. Feeding-fasting driven programs and cell autonomous circadian oscillator act synergistically in the liver to orchestrate daily rhythm in metabolism. However, an imposed feeding-fasting rhythm, as in time-restricted feeding, can drive some rhythm in liver gene expression in clock mutant mice. We tested if TRF alone, in the absence of a circadian clock in the liver or in the whole animal can prevent obesity and metabolic syndrome. Mice lacking the clock component Bmal1 in the liver, Rev-erb alpha/beta in the liver or cry1-/-;cry2-/- (CDKO) mice rapidly gain weight and show genotype specific increased susceptibility to dyslipidemia, hypercholesterolemia and glucose intolerance under ad lib fed condition. However, when the mice were fed the same diet under time-restricted feeding regimen that imposed 10 h feeding during the night, they were protected from weight gain and other metabolic diseases. Transcriptome and metabolome analyses of the liver from there mutant mice showed TRF reduces de novo lipogenesis, increased beta-oxidation independent of a circadian clock. TRF also enhanced cellular defense to metabolic stress. These results suggest a major function of the circadian clock in metabolic homeostasis is to sustain a daily rhythm in feeding and fasting. The feeding-fasting cycle orchestrates a balance between nutrient stress and cellular response to maintain homeostasis.

Time Restricted Feeding Mitigates Obesity Through Adipocyte Thermogenesis

Project description:In obesity, misalignment of feeding time with the light/dark environment results in disruption of peripheral circadian clocks. Conversely, restricting feeding to the active period mitigates metabolic syndrome through mechanisms that remain unknown. Here we show that adipocyte thermogenesis is essential for the healthful metabolic response to time restricted feeding. Genetic enhancement of adipocyte thermogenesis through ablation of Zfp423 attenuates obesity caused by circadian mistimed high fat diet feeding through a mechanism involving creatine metabolism. Circadian control of adipocyte creatine metabolism underlies timing of diet-induced thermogenesis, and enhancement of adipocyte circadian rhythms through overexpression of the clock activator Bmal1 ameliorates metabolic complications during diet induced obesity. These findings establish creatine mediated diet-induced thermogenesis as a bioenergetic mechanism driving metabolic benefits during time-restricted feeding.
