摘要

A growing part of the human population is affected by circadian misalignment caused by deregulated sleep, increased nighttime light exposure and erratic eating patterns. Thus, circadian rhythms are a key research area, with compelling links to cancer. Here, we review the circadian regulation of critical cellular processes, including immunity, metabolism, cell cycle control and DNA repair, under physiological homeostasis and in cancer. We discuss the divergent evidence indicating tissue-specific roles of the circadian clock in different cancer types and the potential link between circadian misalignment and early-onset cancers. Finally, we outline how understanding the circadian clock can improve cancer prevention and chronomedicine-based therapies.
