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.

Serotonin and circadian rhythms. [PDF]

Psychology & Neuroscience, 2010
All mammal behaviors and functions exhibit synchronization with environmental rhythms. This is accomplished through an internal mechanism that generates and modulates biological rhythms. The circadian timing system, responsible for this process, is formed by connected neural structures.

Deciphering Lipid Metabolic Landscape of Sorafenib-Treated Hepatocellular Carcinoma by Mass Spectrometry Imaging and Transcriptomics

Biomolecules
Although sorafenib (SOR) is effective for advanced hepatocellular carcinoma (HCC), significant metabolic heterogeneity limits its therapeutic effect. In this study, we employed high-resolution matrix-assisted laser desorption/ionization mass spectrometry

Genetics of Circadian Rhythms

Neurologic Clinics, 2019
In mammals, genetic influences of circadian rhythms occur at many levels. A set of core "clock genes" have been identified that form a feedback loop of gene transcription and translation. The core genetic clockwork generates circadian rhythms in cells throughout the body.

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 ...

Chronobiology and Mood Disorders [PDF]

Psikiyatride Güncel Yaklaşımlar, 2011
Living organizms show cyclic rhythmicity in a variety of physiological, hormonal, behavioral, and psychological processes. Sleep-wake cycles, body temperature, hormone levels, mood and cognition display a circadian rhythm in humans.
