Bile acid metabolism and sleep: Mechanistic interplay and clinical implications of the gut–liver–brain axis

Sleep Research, EarlyView.
Abstract The bidirectional interplay between sleep and metabolic homeostasis is fundamental to physiological health. While the roles of glucose and lipid metabolism in sleep regulation have been extensively characterized, bile acids (BAs), which are traditionally viewed as digestive surfactants, are emerging as critical metabolic messengers with ...

A hypothetic aging pathway from skin to hypothalamic suprachiasmatic nucleus via slow wave sleep

Sleep Science, 2016
Many observations have demonstrated that the hypothalamic neuroendocrine change determines the chronological sequence of aging in mammals. However, it remains uncertain on the mechanism to account for the hypothalamic aging manifestations.

Circadian clocks and breast cancer [PDF]

, 2016
Circadian clocks respond to environmental time cues to coordinate 24-hour oscillations in almost every tissue of the body. In the breast, circadian clocks regulate the rhythmic expression of numerous genes.

Pineal Gland Volume, Sleep Quality, and Psychiatric Disorders: A Systematic Review and Meta‐Analysis

Acta Psychiatrica Scandinavica, EarlyView.
ABSTRACT Introduction Disturbances in sleep and circadian rhythms are features of several psychiatric disorders. The pineal gland regulates these rhythms via melatonin, with pineal gland volume (PGV) serving as a structural proxy. We conducted a meta‐analysis to synthesize evidence on differences in PGV between patients with psychiatric disorders and ...

Cholecystokinin receptor type A are involved in the circadian rhythm of the mouse retina

Heliyon
The retina is the only organ projecting external light to the suprachiasmatic nucleus. Cholecystokinin receptor type A (Cckar/Cckar) is one of the essential factors for light reception in retinal cells. As there was a lack of literature on the matter, we

Identification of novel light-induced genes in the suprachiasmatic nucleus

BMC Neuroscience, 2007
Background The transmission of information about the photic environment to the circadian clock involves a complex array of neurotransmitters, receptors, and second messenger systems.

A Lavandula angustifolia flower extract and dipeptide‐4 blend modulates oxidative, glycative, autophagic and circadian pathways in human skin models

International Journal of Cosmetic Science, EarlyView.
The blend enhanced antioxidation, anti‐glycation, autophagy and circadian regulation in cell and skin models. Key markers included mitochondrial ROS, γ‐H2AX, AGEs, ATP, melatonin, LC3 and SOD. Significant improvements were visualized via fluorescence and quantified with statistical markers.

Loss of ZBTB20 impairs circadian output and leads to unimodal behavioral rhythms

eLife, 2016
Many animals display morning and evening bimodal activities in the day/night cycle. However, little is known regarding the potential components involved in the regulation of bimodal behavioral rhythms in mammals.

Activation of mGluR1 negatively modulates glutamate-induced phase shifts of the circadian pacemaker in the mouse suprachiasmatic nucleus

Neurobiology of Sleep and Circadian Rhythms, 2023
In mammals, photic information delivered to the suprachiasmatic nucleus (SCN) via the retinohypothalamic tract (RHT) plays a crucial role in synchronizing the master circadian clock located in the SCN to the solar cycle.

Prolonged exposure to artificial light and carcinogenesis: A systematic review of oncostatic mechanisms associated with melatonin pathways

Photochemistry and Photobiology, EarlyView.
Exposure to artificial light at night (ALAN), particularly at blue wavelengths, disrupts circadian rhythms by suppressing melatonin, thereby increasing cancer susceptibility. This systematic review consolidates evidence linking prolonged ALAN exposure to an elevated risk of breast and prostate tumors.
