Circadian rhythms are 24–hour activity cycles that exist for all organisms, from yeast and bacteria to mammals. Epidemiological data has shown that disruptions to circadian rhythms are associated with various diseases, including cancers. Circadian rhythms are regulated at the cellular level by a "molecular clock,” whose oscillations in protein transcription and translation control a range of downstream pathways. However, the connections between altered rhythms and diseases at the molecular level is unclear. Therefore, in this project, I tracked circadian rhythms in a high-resolution manner and thoroughly analyzed them to more completely reflect circadian behaviors and clock functioning at the molecular …
