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 ...

Circadian Rhythms in Cyanobacteria [PDF]
Microbiology 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.
