Circadian rhythm and cancer !

It has been known for quite some time that disrupting sleep and other elements of humans' circadian rhythm can harm health. The same is true for the circadian clock of individual cells as well. So a a group of Japanese scientists wondered if disturbing the circadian clock of cancer cells could potentially hurt/weaken or even kill these cancer cells. They were right indeed...! What these researchers reported that a molecule named GO289 targets an enzyme casein kinase 2 that controls the cell's circadian rhythm, shows great clinical promise in halting cancer cells' growth by enabling manipulation of clock protein phosphorylation.
