Circadian rhythms and hormonal homeostasis: Pathophysiological implications [PDF]
Biology, 2017 Over recent years, a deeper comprehension of the molecular mechanisms that control biological clocks and circadian rhythms has been achieved. In fact, many studies have contributed to unravelling the importance of the molecular clock for the regulation ...

The microbiome stabilizes circadian rhythms in the gut
Proceedings of the National Academy of Sciences of the United States of America, 2023 Significance We demonstrate how the microbiome and rhythms of feeding impact circadian rhythms in the gut. Using a Drosophila model, we show that restricting feeding to specific times of the day strengthens circadian rhythms of gene expression.

Circadian rhythms and cancers: the intrinsic links and therapeutic potentials
Journal of Hematology & Oncology, 2022 The circadian rhythm is an evolutionarily conserved time-keeping system that comprises a wide variety of processes including sleep–wake cycles, eating–fasting cycles, and activity–rest cycles, coordinating the behavior and physiology of all organs for ...

Neuroinflammation, Sleep, and Circadian Rhythms
Frontiers in Cellular and Infection Microbiology, 2022 Molecules involved in innate immunity affect sleep and circadian oscillators and vice versa. Sleep-inducing inflammatory molecules are activated by increased waking activity and pathogens.

Sex Differences in Circadian Rhythms.
Cold Spring Harbor Perspectives in Biology, 2022 Sex as a biological variable is the focus of much literature and has been emphasized by the National Institutes of Health, in part, to remedy a long history of male-dominated studies in preclinical and clinical research.

Circadian rhythms: influence on physiology, pharmacology, and therapeutic interventions
Journal of Pharmacokinetics and Pharmacodynamics, 2021 Circadian rhythms are ubiquitous phenomena that recur daily in a self-sustaining, entrainable, and oscillatory manner, and orchestrate a wide range of molecular, physiological, and behavioral processes.

Circadian Rhythms, Disease and Chronotherapy
Journal of Biological Rhythms, 2021 Circadian clocks are biological timing mechanisms that generate 24-h rhythms of physiology and behavior, exemplified by cycles of sleep/wake, hormone release, and metabolism.

Rhythms of Locomotion Expressed by Limulus polyphemus, the American Horseshoe Crab: II. Relationship to Circadian Rhythms of Visual Sensitivity [PDF]
, 2008 In the laboratory, horseshoe crabs express a circadian rhythm of visual sensitivity as well as daily and circatidal rhythms of locomotion. The major goal of this investigation was to determine whether the circadian clock underlying changes in visual ...
