Metformin Regulation of the Liver Circadian Clock and Metabolic Aging: A Systems Modeling Study [PDF]

open access: yesMetabolites
Introduction: Aging affects both metabolic and circadian systems, leading to disruptions in energy homeostasis and phase shifts in the circadian clock. Metformin, a widely used antihyperglycemic drug, exerts anti-aging effects by modulating key pathways ...

Mood phenotypes in rodent models with circadian disturbances

open access: yesNeurobiology of Sleep and Circadian Rhythms, 2022
Many physiological functions with approximately 24-h rhythmicity (circadian rhythms) are generated by an internal time-measuring system of the circadian clock.

Circadian Biology: Clocks within Clocks [PDF]

open access: yesCurrent Biology, 2005
A small cluster of approximately 20,000 neurons in the ventral hypothalamus provide the body with key time-keeping signals and drive circadian rhythms. This circadian clock exhibits surprisingly complex substructures, with inputs from the retina, and outputs to other brain structures.

Circadian Clocks: Translation Lost [PDF]

open access: yesCurrent Biology, 2005
One of the big questions in biological rhythms research is how a stable and precise circa-24 hour oscillation is generated on the molecular level. While increasing complexity seemed to be the key, a recent report suggests that circa-24 hour rhythms can be generated by just four molecules incubated in a test tube.

Circadian clock—A promising scientific target in oral science

open access: yesFrontiers in Physiology, 2022
The oral and maxillofacial organs play vital roles in chewing, maintaining facial beauty, and speaking. Almost all physiological processes display circadian rhythms that are driven by the circadian clock, allowing organisms to adapt to the changing ...

Circadian clock: a regulator of the immunity in cancer

open access: yesCell Communication and Signaling, 2021
The circadian clock is an endogenous timekeeper system that controls and optimizes biological processes, which are consistent with a master circadian clock and peripheral clocks and are controlled by various genes.

Silybin A enhances circadian clock by targeting CRY1 and disrupting its interaction with CLOCK

open access: yesPharmacological Research - Modern Chinese Medicine, 2022
Circadian clock governs a large array of physiological and metabolic functions. The amplitude decline of circadian rhythm is associated with various chronic diseases. However, few clock enhancing-molecules are known. CRY1 is one of the main components of

Tuning up an aged clock: Circadian clock regulation in metabolism and aging

open access: yesTranslational Medicine of Aging, 2022
Circadian rhythms provide temporal variation of a broad range of behavioral and physiological functions, which is precisely controlled by the internal molecular gear, the circadian clock.

Circadian Rhythms in the CNS and Peripheral Clock Disorders: The Circadian Clock and Hyperlipidemia

open access: yesJournal of Pharmacological Sciences, 2007
A circadian clock controls various physiological and behavioral rhythms. In mammals, a master circadian clock exists in the suprachiasmatic nucleus of the hypothalamus, and slave oscillators can be found in most tissues.
