Curr Top Med Chem. 2019 Nov 17. doi: 10.2174/1568026619666191118110155. [Epub ahead of print] Abstract Abstract BACKGROUND: Sleep disorders have emerged as potential cancer risk factors. OBJECTIVE: This review discusses the relationships between sleep, obesity, and breathing disorders with concomitant risks of developing cancer. RESULTS: Sleep disorders result in an abnormal expression of clock genes, decreased immunity,...

Horm Behav. 2019 Apr;110:77-89. doi: 10.1016/j.yhbeh.2019.02.018. Epub 2019 Mar 15. Abstract Circadian time-keeping mechanisms preserve homeostasis by synchronizing internal physiology with predictable variations in the environment and temporally organize the activation of physiological signaling mechanisms to promote survival and optimize the allocation of energetic resources. In this paper, we highlight the importance of the robust circadian...

by Elise McGlashan, PhD & Parisa Vidafar, PhD on November 5, 2019 in Clocks in the Spotlight Image credit: Olivia Walch (Twitter: @OliviaWalch; website: www.oliviawalch.com)  Humans evolved in an environment with only very bright (sun) or very dim (moon or fire) sources of light. Today, artificial lighting enables us to spend hours per day at intermediate light levels. Our recent study shows...

PNAS June 11, 2019 116 (24) 12019-12024; first published May 28, 2019 https://doi.org/10.1073/pnas.1901824116 Significance: Electric lighting has fundamentally altered how the human circadian clock synchronizes to the day/night cycle. Exposure to light after dusk is pervasive in the modern world. We examined group-level sensitivity of the circadian system to evening light and the degree to which sensitivity varies between individuals. We...

Abstract Both obesity and breast cancer are already recognized worldwide as the most common syndromes in our modern society. Currently, there is accumulating evidence from epidemiological and experimental studies suggesting that these syndromes are closely associated with circadian disruption. It has been suggested that melatonin (MLT) and the circadian clock genes both play an important...

Published: 17 October 2019  Abstract: Light is necessary for life, but prolonged exposure to artificial light is a matter of increasing health concern. Humans are exposed to increased amounts of light in the blue spectrum produced by light-emitting diodes (LEDs), which can interfere with normal sleep cycles. The LED technologies are relatively new; therefore, the long-term...
