Effect of H₂S on the circadian rhythm of mouse hepatocytes

Lipids in Health and Disease, 2012
Background Dysregulation of circadian rhythms can contribute to diseases of lipid metabolism. NAD-dependent deacetylase sirtuin-1(SIRT1) is an important hub which links lipid metabolism with circadian clock by its deacetylation activity depends on ...

Keeping time in the dark: Potato diel and circadian rhythmic gene expression reveals tissue‐specific circadian clocks

Plant Direct, 2022
The circadian clock is an internal molecular oscillator and coordinates numerous physiological processes through regulation of molecular pathways. Tissue‐specific clocks connected by mobile signals have previously been found to run at different speeds in

Circadian Clock Genes in Diabetic Kidney Disease (DKD) [PDF]

Current Diabetes Reports, 2019
The purpose of this review is to provide a brief summary about the current state of knowledge regarding the circadian rhythm in the regulation of normal renal function.There is a lack of information regarding how the circadian clock mechanisms may contribute to the development of diabetic kidney disease.

Brain-specific rescue of Clock reveals system-driven transcriptional rhythms in peripheral tissue.

PLoS Genetics, 2012
The circadian regulatory network is organized in a hierarchical fashion, with a central oscillator in the suprachiasmatic nuclei (SCN) orchestrating circadian oscillations in peripheral tissues.

The role and implications of mammalian cellular circadian entrainment

FEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

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 ...

The Circadian Clock Gene BMAL1 Coordinates Intestinal Regeneration [PDF]

Cellular and Molecular Gastroenterology and Hepatology, 2017
The gastrointestinal syndrome is an illness of the intestine caused by high levels of radiation. It is characterized by extensive loss of epithelial tissue integrity, which initiates a regenerative response by intestinal stem and precursor cells. The intestine has 24-hour rhythms in many physiological functions that are believed to be outputs of the ...

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

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 ...

Ror homolog nhr-23 is essential for both developmental clock and circadian clock in C. elegans

Communications Biology
Animals have internal clocks that generate biological rhythms. In mammals, clock genes such as Period form the circadian clock to generate approximately 24-h biological rhythms. In C. elegans, the clock gene homologs constitute the “developmental clock”,

A network of pro-inflammatory genes repressed by clock signalling in bronchial epithelium

ERJ Open Research
Background Circadian rhythms are biological cycles that regulate various physiological processes, including immune responses, tissue repair and oxidative stress. Previous studies indicated a role for distorted circadian signalling in COPD.
