Circadian rhythms in thrombosis and atherothrombotic events
Frontiers in Bioscience-Landmark, 2022 Biological circadian rhythms in living organisms are regulated by molecular clocks. Several of these clocks are present in blood vessels, peripheral tissues, and immune cells.

Vasoactive intestinal polypeptide mediates circadian rhythms in Mammalian olfactory bulb and olfaction [PDF]
, 2014 Accumulating evidence suggests that the olfactory bulbs (OBs) function as an independent circadian system regulating daily rhythms in olfactory performance.

Molecular bases of circadian magnesium rhythms across eukaryotes
FEBS Letters, EarlyView.Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Circadian Rhythms and Mood Disorders: Are The Phenomena and Mechanisms Causally Related?
Frontiers in Psychiatry, 2015 This paper reviews some of the compelling evidence of disrupted circadian rhythms in individuals with mood disorders (major depressive disorder, seasonal affective disorder, and bipolar disorder) and that treatments such as bright light, designed to ...

Mouse circadian plasma leptin and active ghrelin rhythms under ad libitum and scheduled feeding [PDF]
, 2007 Thesis (M.S.) University of Alaska Fairbanks, 2007Light is the strongest timing cue for the circadian system, but non-photic cues can also entrain the master circadian clock, i.e., suprachiasmatic nuclei (SCN).

Feeding Rhythms and the Circadian Regulation of Metabolism
Frontiers in Nutrition, 2020 The molecular circadian clock regulates metabolic processes within the cell, and the alignment of these clocks between tissues is essential for the maintenance of metabolic homeostasis.

FEBS Letters, EarlyView.This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Analysis of Saccharomyces cerevisiae Circadian Rhythms in Continuous Culture [PDF]
, 2012 The circadian rhythm is a roughly 24-hour cycle in the physiological processes of organisms. There have been many studies on the circadian rhythms in other model organisms, but not in Saccharomyces cerevisiae. To study the rhythm in S.

Circadian rhythms in murine pups develop in absence of a functional maternal circadian clock [PDF]
, 2006 A genetic approach was used to investigate whether the emergence of circadian rhythms in murine pups is dependent on a functional maternal clock. Arrhythmic females bearing either the mPer1Brdm1/Per2Brdm1 or mPer2Brdm1/Cry1-/- double-mutant genotype were

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...
