Circadian Rhythms in Cyanobacteria [PDF]

open access: yesMicrobiology and Molecular Biology Reviews, 2015
SUMMARY Life on earth is subject to daily and predictable fluctuations in light intensity, temperature, and humidity created by rotation of the earth. Circadian rhythms, generated by a circadian clock, control temporal programs of cellular physiology to facilitate adaptation to daily environmental changes.

Circadian rhythms and cancers: the intrinsic links and therapeutic potentials

open access: yesJournal 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 ...

Circadian rhythms in RA [PDF]

open access: yesAnnals of the Rheumatic Diseases, 2003
Possible roles of cortisol and melatonin It is well known that some clinical signs and symptoms of rheumatoid arthritis (RA) vary within a day and between days, and the morning stiffness seen in patients with RA has become one of the diagnostic criteria of the disease (fig 1).1 Figure 1 Clinical signs and symptoms of articular inflammation in ...

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

open access: yesActa 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.

Circadian rhythms and fertility [PDF]

open access: yesMolecular and Cellular Endocrinology, 2012
Circadian rhythms impact on a wide range of physiological systems and this impact extends to fertility, such that disruptions to timing systems can impact upon reproductive capacity. This is highlighted most obviously in mutant mouse models whereby deletion or mutation of single genes results not only in disrupted circadian rhythmicity, but also ...
