Abstract
Several physiological activities of organisms are coordinated based on periodic variations of ~24 h, which is called a circadian rhythm. Circadian rhythms, driven by circadian clock genes, play an important role in the regulation of various complex life activities of organisms, in an orderly and coordinated manner. Period (Per)1/2/3 genes are important core clock genes and part of the Per gene family. Current research has demonstrated that the abnormal expression of Per genes and disruption of circadian rhythms can lead to the occurrence and development of cancer; however, the exact mechanism has not yet been elucidated. Further study on this mechanism may lead to the discovery of new, effective therapies for the prevention and treatment of cancer. The present review summarizes the status of current research with regards to the association between the abnormal expression and rhythmic variation of the Per gene family, and carcinogenesis and progression of cancer.
