and maximal for a continuous infusion or a circadian pattern peaking at 4 p.m.328, 349, 350, 351 The existence of a cancer‐specific molecular clock can be used for the discovery and development of novel, therapeutic approaches to treat cancer.352 A pharmacological modulation of clock‐related proteins may be a suitable strategy for the identification of innovative anticancer approaches.353 To date, chronotherapy has been studied for some conventional anticancer agents, while data for MTT class and immunotherapies seem to be lacking. Here, CLOCK is linked to cancer.
