Cortisol on Circadian Rhythm and Its Effect on Cardiovascular System

open access: yesInternational Journal of Environmental Research and Public Health, 2021
The synthesis and secretion of cortisol are controlled by the hypothalamic–pituitary–adrenal axis. Cortisol exhibits a proper 24-h circadian rhythm that affects the brain, the autonomic nervous system, the heart, and the vasculature that prepares the ...

Circadian Rhythm, Clock Genes, and Hypertension: Recent Advances in Hypertension

open access: yesHYPERTENSION, 2021
Accumulating evidence suggests that the molecular circadian clock is crucial in blood pressure (BP) control. Circadian rhythms are controlled by the central clock, which resides in the suprachiasmatic nucleus of the hypothalamus and peripheral clocks ...

Circadian rhythm disruption and mental health

open access: yesTranslational Psychiatry, 2020
Circadian rhythms are internal manifestations of the solar day that permit adaptations to predictable environmental temporal changes. These ~24-h rhythms are controlled by molecular clockworks within the brain that are reset daily to precisely 24 h by ...

AMPK regulates circadian rhythms in a tissue- and isoform-specific manner. [PDF]

open access: yesPLoS ONE, 2011
AMP protein kinase (AMPK) plays an important role in food intake and energy metabolism, which are synchronized to the light-dark cycle. In vitro, AMPK affects the circadian rhythm by regulating at least two clock components, CKIα and CRY1, via direct ...

Circadian secretion rhythm of GLP-1 and its influencing factors

open access: yesFrontiers in Endocrinology, 2022
Circadian rhythm is an inherent endogenous biological rhythm in living organisms. However, with the improvement of modern living standards, many factors such as prolonged artificial lighting, sedentarism, short sleep duration, intestinal flora and high ...

Circadian rhythms, cardiac arrhythmias and sudden death

open access: yesFrontiers in Bioscience-Landmark, 2021
The heart, like most mammalian organs, is influenced by circadian patterns. The suprachiasmatic nucleus in the hypothalamus has a key role in this influence, via various neurohumoral factors, particularly the autonomic nervous system.
