Circadian clock: a regulator of the immunity in cancer

March 23, 2021
Zhang, Z., Zeng, P., Gao, W. et al. Circadian clock: a regulator of the immunity in cancer. Cell Commun Signal 19, 37 (2021). https://doi.org/10.1186/s12964-021-00721-2 Abstract The circadian clock is an endogenous timekeeper system that controls and optimizes biological processes, which are consistent with a master circadian clock and peripheral clocks and are controlled by various genes. Notably, the disruption of...

The circadian clock and metabolic homeostasis: entangled networks

March 15, 2021
de Assis, L.V.M., Oster, H. The circadian clock and metabolic homeostasis: entangled networks. Cell. Mol. Life Sci. (2021). https://doi.org/10.1007/s00018-021-03800-2 Abstract The circadian clock exerts an important role in systemic homeostasis as it acts a keeper of time for the organism. The synchrony between the daily challenges imposed by the environment needs to be aligned with biological processes...
