Circadian Factors And Cancer Survivorship: A Mini Review

Circadian clocks are molecular clocks that govern the temporal control of physiology to preserve homeostasis. The disruption of the circadian rhythm is important in carcinogenesis and aids the development of cancer hallmarks. On the other hand, carcinogenic activities disrupt circadian rhythms directly. In cancer treatment, pharmacological regulation of core clock genes is a novel approach. The use of circadian biology in cancer research opens up new avenues for improving cancer treatment effectiveness. This mini-review provides an overview of relationship between circadian factors including circadian gene expression, circadian genotype, circadian disruption and circadian gene methylation and the cancer survivorship. The review also discusses implications of chronotherapy on cancer treatment by regulating the circadian factors among cancer patients
