| Outline of Final Research Achievements |
Although disruption of circadian clock machinery is thought to increase the risk of cancer development, there is no preventive strategy against oncogenesis which is caused by circadian clock disruption. Circadian rhythms in physiological function are generated by a molecular oscillator driven by transcriptional-translational feedback loop consisting of negative and positive regulators. Genetic ablation of either negative or positive transcriptional regulators of the circadian clock leads to disrupted rhythms in physiological functions, but we found that negative and positive transcriptional regulators of circadian feedback loop had different roles in oncogene-induced neoplastic transformation. Our findings suggest that appreciation of the mechanism for circadian clock disruption is important for prevention of cancer development.
