DNA damage and the circadian clock [PDF]
BioDiscovery, 2014 The role of the circadian clock has already been demonstrated for virtually all physiological processes, but it was only recently shown that cells were more sensitive to DNA damage at specific times of the day; that the peak of synthesis of mRNA and proteins of genes coding for products involved directly or indirectly in DNA repair was differentially ...

Advanced Science, EarlyView.This study identifies a class of amino acid‐sensing neurons, APCCRH neurons, which regulate BAT thermogenesis. Leucine deficiency alters intrinsic excitability through GCN2 signaling pathway, activating APCCRH neurons, which in turn regulate BAT thermogenesis via projections to the lateral hypothalamus.

Barley Hv CIRCADIAN CLOCK ASSOCIATED 1 and Hv PHOTOPERIOD H1 Are Circadian Regulators That Can Affect Circadian Rhythms in Arabidopsis. [PDF]
PLoS ONE, 2015 Circadian clocks regulate many aspects of plant physiology and development that contribute to essential agronomic traits. Circadian clocks contain transcriptional feedback loops that are thought to generate circadian timing.

Influence of photic perturbations on circadian rhythms [PDF]
arXiv, 2019 The circadian clock is the molecular mechanism responsible for the adaptation to daily rhythms in living organisms. Oscillations and fluctuations in environmental conditions regulate the circadian clock through signaling pathways. We study the response to continuous photic perturbations in a minimal molecular network model of the circadian clock ...

Circadian Clock Control of Liver Metabolic Functions.
Gastroenterology, 2016 The circadian clock is an endogenous biological timekeeping system that synchronizes physiology and behavior to day/night cycles. A wide variety of processes throughout the entire gastrointestinal tract and notably the liver appear to be under circadian ...

The accuracy of telling time via oscillatory signals [PDF]
, 2016 Circadian clocks are the central timekeepers of life, allowing cells to anticipate changes between day and night. Experiments in recent years have revealed that circadian clocks can be highly stable, raising the question how reliably they can be read out.

American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Prader‐Willi syndrome (PWS) is a neurodevelopmental disorder typically caused by large deletions or imprinting defects on chromosome 15q11.2, encompassing multiple genes. While the contribution of individual genes to the PWS phenotype remains unclear, previous studies suggested that isolated deletions of MAGEL2, NDN, and MKRN3, excluding the ...
