Dong Zhang, Rena R. Jones, Peter James, Cari M. Kitahara, and Qian Xiao. Associations between artificial light at night and risk for thyroid cancer: a large U.S. cohort study. Cancer, 2021 DOI: 10.1002/cncr.33392 Abstract Background Light at night (LAN) inhibits nighttime secretion of melatonin and may cause circadian disruption, which may be a risk factor for cancer. Recent...

A genome-wide microRNA screen identifies the microRNA-183/96/182 cluster as a modulator of circadian rhythms. Lili Zhou, Caitlyn Miller, Loren J. Miraglia, Angelica Romero, Ludovic S. Mure, Satchidananda Panda, Steve A. Kay Proceedings of the National Academy of Sciences Jan 2021, 118 (1) e2020454118; DOI: 10.1073/pnas.2020454118 Significance Although miRNAs are emerging as important regulators of diverse physiological and pathological processes, our knowledge of their potential role in regulation of circadian rhythms is still limited. We...

Pelham, J.F., Dunlap, J.C. & Hurley, J.M. Intrinsic disorder is an essential characteristic of components in the conserved circadian circuit. Cell Commun Signal 18, 181 (2020). https://doi.org/10.1186/s12964-020-00658-y Video Abstract: Introduction The circadian circuit, a roughly 24 h molecular feedback loop, or clock, is conserved from bacteria to animals and allows for enhanced organismal survival by facilitating the anticipation of...

Science  04 Sep 2020:Vol. 369, Issue 6508, pp. 1164-1165DOI: 10.1126/science.abd4964 Summary Circadian rhythms, or the body clock, confer temporal structure on human behavior and physiology to align homeostatic processes with anticipated changes in the environment. Disruption of these rhythms can influence health and well-being. Chronobiological research has often failed to consider how this temporal organization may...
