Circadian clocks: running on redox.

Cell, 2001
The circadian clock in all organisms is so intimately linked to light reception that it appears as if evolution has simply wired a timer into the mechanism that processes photic information. Several recent studies have provided new insights into the role of light input pathways in the circadian system of Arabidopsis.

Endogenous melatonin promotes rhythmic recruitment of neutrophils toward an injury in zebrafish

Scientific Reports, 2017
Neutrophil recruitment to injured tissue appears to be an evolutionarily conserved strategy for organisms to fight against exogenous insults. Recent studies have shown rhythmic migration of neutrophils and several factors, including melatonin, have been ...

Social information as an entrainment cue for the circadian clock [PDF]

Genetics and Molecular Biology
Animals adapt to the daily changes in their environmental conditions by means of genetically encoded circadian clocks. These clocks, found throughout the tree of life, regulate diverse biological functions, and allow periodical changes in physiology and ...

Quantitative analysis of regulatory flexibility under changing environmental conditions [PDF]

, 2010
The circadian clock controls 24-h rhythms in many biological processes, allowing appropriate timing of biological rhythms relative to dawn and dusk. Known clock circuits include multiple, interlocked feedback loops.

Thousands of oscillating LncRNAs in the mouse testis

Computational and Structural Biotechnology Journal
The long noncoding RNAs (lncRNAs) are involved in numerous fundamental biological processes, including circadian regulation. Although recent studies have revealed insights into the functions of lncRNAs, how the lncRNAs regulate circadian rhythms still ...

Intestinal Stem Cells Exhibit Conditional Circadian Clock Function

Stem Cell Reports, 2018
Summary: The circadian clock is a molecular pacemaker that produces 24-hr physiological cycles known as circadian rhythms. How the clock regulates stem cells is an emerging area of research with many outstanding questions.

Chronic Treatment with Metformin Has No Disrupting Effect on the Hepatic Circadian Clock in Mice

Medicina, 2022
Background and Objectives: The antidiabetic agent metformin is known to activate AMP-activated protein kinase (AMPK) in various tissues. Because AMPK can modulate intracellular circadian clocks through regulating the stability of clock components, a ...

Circadian clocks of both plants and pollinators influence flower seeking behavior of the pollinator hawkmoth Manduca sexta

Scientific Reports, 2018
Most plant-pollinator interactions occur during specific periods during the day. To facilitate these interactions, many flowers are known to display their attractive qualities, such as scent emission and petal opening, in a daily rhythmic fashion ...
