Circadian Rhythm Sleep Disorders: Genetics, Mechanisms, and Adverse Effects on Health

open access: yesFrontiers in Genetics, 2022
Nearly all living organisms, from cyanobacteria to humans, have an internal circadian oscillation with a periodicity of approximately 24 h. In mammals, circadian rhythms regulate diverse physiological processes including the body temperature, energy ...

Role of Sleep Restriction in Daily Rhythms of Expression of Hypothalamic Core Clock Genes in Mice

open access: yesCurrent Issues in Molecular Biology, 2022
Lack of sleep time is a menace to modern people, and it leads to chronic diseases and mental illnesses. Circadian processes control sleep, but little is known about how sleep affects the circadian system.
