Investigating the Relationships Between Hypothalamic Volume and Measures of Circadian Rhythm and Habitual Sleep in Premanifest Huntington’s Disease [PDF]

, 2019
Objective: Pathological changes within the hypothalamus have been proposed to mediate circadian rhythm and habitual sleep disturbances in individuals with Huntington’s disease (HD). However, investigations examining the relationships between hypothalamic

Sleep, circadian rhythm, and physical activity patterns in depressive and anxiety disorders: A 2‐week ambulatory assessment study

Depression and Anxiety, 2019
Actigraphy may provide a more valid assessment of sleep, circadian rhythm (CR), and physical activity (PA) than self‐reported questionnaires, but has not been used widely to study the association with depression/anxiety and their clinical characteristics.

Circadian rhythms and cancers: the intrinsic links and therapeutic potentials

Journal of Hematology & Oncology, 2022
The circadian rhythm is an evolutionarily conserved time-keeping system that comprises a wide variety of processes including sleep–wake cycles, eating–fasting cycles, and activity–rest cycles, coordinating the behavior and physiology of all organs for ...

Altered expression of circadian clock gene, mPer1, in mouse brain and kidney under morphine dependence and withdrawal [PDF]

, 2006
Every physiological function in the human body exhibits some form of circadian rhythmicity. Under pathological conditions, however, circadian rhythmicity may be dusrupted.

Reduced expression of the PER2 protein contributes to β₁-AA-induced cardiac autophagy rhythm disorders

Acta Biochimica et Biophysica Sinica
Heart failure may be linked to fluctuations in the rhythm of autophagy in cardiomyocytes throughout the day. Circadian rhythms depend on the regulation of core biological clock proteins, with PER2 playing a crucial role.

CHRONO and DEC1/DEC2 compensate for lack of CRY1/CRY2 in expression of coherent circadian rhythm but not in generation of circadian oscillation in the neonatal mouse SCN

Scientific Reports, 2021
Clock genes Cry1 and Cry2, inhibitory components of core molecular feedback loop, are regarded as critical molecules for the circadian rhythm generation in mammals.

Circadian and Ultradian Rhythms of Free Glucocorticoid Hormone Are Highly Synchronized between the Blood, the Subcutaneous Tissue, and the Brain [PDF]

, 2012
Total glucocorticoid hormone levels in plasma of various species, including humans, follow a circadian rhythm that is made up from an underlying series of hormone pulses. In blood most of the glucocorticoid is bound to corticosteroid-binding globulin and

Circadian rhythm regulates the function of immune cells and participates in the development of tumors

Cell Death Discovery
Circadian rhythms are present in almost all cells and play a crucial role in regulating various biological processes. Maintaining a stable circadian rhythm is essential for overall health. Disruption of this rhythm can alter the expression of clock genes
