Dynamical analysis of the effects of circadian clock on the neurotransmitter dopamine

open access: yesMathematical Biosciences and Engineering, 2023
The circadian clock is an autonomous timing system that regulates the physiological and behavioral activities of organisms. Dopamine (DA) is an important neurotransmitter that is associated with many biological activities such as mood and movement ...

Circadian Clocks and Pregnancy [PDF]

open access: yesFrontiers 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.

Circadian rhythms in the absence of the clock gene Bmal1

open access: yesScience, 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.

Crosstalk between the circadian clock and innate immunity in Arabidopsis. [PDF]

open access: yesPLoS 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.

A Long Noncoding RNA Perturbs the Circadian Rhythm of Hepatoma Cells to Facilitate Hepatocarcinogenesis

open access: yesNeoplasia: An International Journal for Oncology Research, 2015
Clock circadian regulator (CLOCK)/brain and muscle arnt-like protein-1 (BMAL1) complex governs the regulation of circadian rhythm through triggering periodic alterations of gene expression.

Parallel analysis of Arabidopsis circadian clock mutants reveals different scales of transcriptome and proteome regulation [PDF]

open access: yesOpen 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 Clocks and Metabolism [PDF]

open access: yes, 2013
Circadian clocks maintain periodicity in internal cycles of behavior, physiology, and metabolism, enabling organisms to anticipate the 24-h rotation of the Earth. In mammals, circadian integration of metabolic systems optimizes energy harvesting and utilization across the light/dark cycle.

Circadian clock protein Rev-erbα regulates neuroinflammation

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2019
Significance Disruptions in the circadian clock and its component proteins have been shown to be associated with disease states ranging from cancer to neurodegeneration.

Neuroimmunology of the circadian clock

open access: yesBrain Research, 2008
Circadian timekeeping is a ubiquitous feature of all eukaryotes which allows for the imposition of a biologically appropriate temporal architecture on an animal's physiology, behavior and metabolism. There is growing evidence that in mammals the processes of circadian timing are under the influence of the immune system.
