Feeding and circadian clocks [PDF]
Reproduction Nutrition Development, 2006 The mammalian genome encodes at least a dozen of genes directly involved in the regulation of the feedback loops constituting the circadian clock. The circadian system is built up on a multitude of oscillators organized according to a hierarchical model in which neurons of the suprachiasmatic nuclei of the hypothalamus may drive the central circadian ...

Circadian Clocks and Pregnancy [PDF]
Frontiers in Endocrinology, 2014 The recognition that 24-h rhythmic processes (“circadian”) underlie many endocrine functions has added a fascinating new temporal dimension to our appreciation of their complexity. Research from various laboratories has revealed circadian gene expression in multiple tissues in the reproductive system of non-pregnant and pregnant mammals.

Network Dynamics Mediate Circadian Clock Plasticity [PDF]
, 2017 A circadian clock governs most aspects of mammalian behavior. Although its properties are in part genetically determined, altered light-dark environment can change circadian period length through a mechanism requiring de novo DNA methylation.

Crosstalk between the circadian clock and innate immunity in Arabidopsis. [PDF]
PLoS Pathogens, 2013 The circadian clock integrates temporal information with environmental cues in regulating plant development and physiology. Recently, the circadian clock has been shown to affect plant responses to biotic cues.

Rodent models for the analysis of tissue clock function in metabolic rhythms research [PDF]
, 2017 The circadian timing system consists on a distributed network of cellular clocks that together coordinate 24-h rhythms of physiology and behavior. Clock function and metabolism are tightly coupled, from the cellular to the organismal level.

Thyroxine differentially modulates the peripheral clock: lessons from the human hair follicle [PDF]
, 2015 The human hair follicle (HF) exhibits peripheral clock activity, with knock-down of clock genes (BMAL1 and PER1) prolonging active hair growth (anagen) and increasing pigmentation.

Parallel analysis of Arabidopsis circadian clock mutants reveals different scales of transcriptome and proteome regulation [PDF]
Open Biology, 2017 The circadian clock regulates physiological processes central to growth and survival. To date, most plant circadian clock studies have relied on diurnal transcriptome changes to elucidate molecular connections between the circadian clock and observable ...

Circadian control of interferon-sensitive gene expression in murine skin. [PDF]
, 2020 The circadian clock coordinates a variety of immune responses with signals from the external environment to promote survival. We investigated the potential reciprocal relationship between the circadian clock and skin inflammation.

Circadian rhythms in the absence of the clock gene Bmal1
Science, 2020 Redundancy in circadian clocks? The transcription factor BMAL1 is a core component of the mammalian circadian clock; without it, circadian behaviors are abolished. However, Ray et al.
