Macromolecular assemblies of the mammalian circadian clock
Molecules and Cells, 2017 The mammalian circadian clock is built on a feedback loop in which PER and CRY proteins repress their own transcription. We found that in mouse liver nuclei all three PERs, both CRYs, and Casein Kinase-1δ (CK1δ) are present together in a ~1.9-MDa ...

Advanced Science, EarlyView.An optimized single‐cell transcriptomic framework profiles over 60 000 cells to map the ovine rumen microbiome, partitioning the ecosystem into seven cross‐species functional clusters. In heat‐resistant hosts, a lineage‐specific metabolic shift in Anaerovibrio lipolyticus toward a highly glycolytic phenotype contributes to a “nutritional sparing ...

Advanced Science, EarlyView.Wearable‐derived diurnal alignment between physical activity and device temperature, decomposed into 24 h coupling strength (M24), phase deviation (D24), and 12 h harmonic magnitude (M12), is examined in approximately 90,000 UK Biobank participants.

Advanced Science, EarlyView.Multi‐trait genome‐wide association mapping identifies a central hub regulator, COLD AND CATECHINS REGULATOR 1 (CCR1), and its excellent natural allele variation, coordinately enhancing cold tolerance and promoting catechins biosyntheis. CsCCR1 interacts with CsCBF1/3 and is transcriptionally activated by CsLUX and CsKUA1 to promote catechins ...

Physcion Protects Against Ethanol-Induced Liver Injury by Reprogramming of Circadian Clock
Frontiers in Pharmacology, 2020 The circadian clock plays a key role in our daily physiology and metabolism. Alcohol consumption disrupts the circadian rhythm of metabolic genes in the liver; however, the potential contribution of circadian clock modulation to alcoholic liver disease ...

Regulation of amyloid-β dynamics and pathology by the circadian clock
Journal of Experimental Medicine, 2018 Nighttime restlessness and daytime drowsiness are common and early symptoms of Alzheimer’s Disease (AD). This symptomology implicates dysfunctional biological timing, yet the role of the circadian system in AD pathogenesis is unknown.

Advanced Science, EarlyView.Human neutrophils exist as two epigenetically imprinted subtypes defined by stable CD177 expression or absence — a ratio that persists across time, circadian rhythms, and inflammation. CD177− neutrophils display a distinct molecular landscape enriched in arginase 1 and lipid metabolism markers, accumulate in head‐and‐neck tumors, and associate with ...

Advanced Science, EarlyView.An intelligent odor monitoring system integrates an IVC animal model, gas sensor array, real‐time resistance readout, and machine‐learning analysis to continuously monitor infection‐associated odor changes. The platform captures longitudinal sensor responses, distinguishes infected from healthy states, and supports early‐stage respiratory viral ...

Hepatic gene therapy rescues high-fat diet responses in circadian Clock mutant mice
Molecular Metabolism, 2017 Objective: Circadian Clock gene mutant mice show dampened 24-h feeding rhythms and an increased sensitivity to high-fat diet (HFD) feeding. Restricting HFD access to the dark phase counteracts its obesogenic effect in wild-type mice.

Cell-autonomous clock of astrocytes drives circadian behavior in mammals
Science, 2019 Astrocytes can drive the master clock in the brain The neurons of the suprachiasmatic nucleus (SCN) of the hypothalamus function as a central circadian clock, coordinating mammalian physiology with the 24-hour light-dark cycle. Brancaccio et al.
