描述信息 This project investigated the coupling between the circadian clock and metabolism under physiological conditions and the underlying mechanism of maintaining homeostasis of tissues and organs, the mechanism of circadian misalignment leading to metabolic disorders and metabolic diseases of important tissues and organs, and establish methods for employing metabolites to interveneor modulate circadian clock disorders. We used the model organisms fruitflies, zebrafish and mice, as well as using "gene trap-based tissue-specific reconstitution technology" to establish new animal models of tissue-specific reconstitution and recombination reconstitution, zebrafish high-throughput metabolite screening technology, and multi-omics analysis and other technologies: (1) to screen, identify and study the key genes and metabolites of hierarchical coupling and parallel coupling between the circadian clock and metabolism in important tissues and organs; to elucidate the circadian mechanism underlying the coupling and homeostasis maintenance of the circadian clock and metabolism in important tissues and organs, and conduct cross-species comparisons of the circadian clock and metabolism coupling and homeostasis maintenance mechanisms; (2) to use multi-omics technologies to analyze the circadian clock genes of animals including fruitflies, zebrafish and mice with abnormal circadian clocks; (3) Using new tissue-specific reconstruction models (such as Bmal1/bmal1a/cycle) and related knockout models, as well as three types of model animals induced by light exposure, abnormal feeding, etc., to determine the changes in genes, proteins and metabolites of important tissues and organs, including the brain, liver, intestine and pancreas, and to identify the health status of experimental animals through key physiological and pathological indicators, in order to study the pathogenesis of metabolic disorders caused by abnormal circadian clock at the molecular and cellular levels; (4) Using transgenic zebrafish containing luciferase driven by E-box, RRE-box or D-box-containing promoters, and zebrafish induced by light exposure and abnormal feeding in the background of important circadian clock gene mutations, to screen approximately 10,000 metabolites/compounds to identify metabolites that can change the period, phase or amplitude of the circadian clock or intervene/adjust circadian clock abnormalities; use fruitflies, zebrafish and mice to study the methods and mechanisms of metabolites to interveneor modulate circadian clock abnormalities; to study the mechanism of action of adenosine and metformin on the circadian clocks of nematodes, fruit flies, zebrafish, and mice, and use multi-omics and other technologies to analyze the oscillation patterns of adenosine and its related metabolic enzymes in the brain, liver, intestine, etc. of four model animals, as well as the patterns and mechanisms of changes in the transcriptome, proteome, and metabolome of three model animals treated with adenosine, adenosine receptor antagonists, and metformin; use blood samples from obese and diabetic patients and liver samples from corresponding mouse, zebrafish, and fruit fly metabolic disease models to conduct omics analysis to clarify new mechanisms of the effects of obesity and diabetes on the circadian clock. To this end, this project has set up three closely related research subprojects: Subproject 1, the coupling between the circadian clock and the metabolism of important tissues and organs and the mechanism of maintaining homeostasis; Subproject 2, the pathogenesis of metabolic disorders of important tissues and organs caused by circadian misalignment; Subproject 3, investigation of metabolite intervention for circadian clock disorders.
