Clarkson-Townsend DA, Bales KL, Hermetz KE, et al. Developmental chronodisruption alters placental signaling in mice. Plos one. 2021 ;16(8):e0255296. DOI: 10.1371/journal.pone.0255296. PMID: 34370755; PMCID: PMC8351967. Abstract Chronodisruption has been largely overlooked as a developmental exposure. The placenta, a conduit between the maternal and fetal environments, may relay circadian cues to the fetus. We have previously...

In mammals, the central circadian pacemaker, which is located in the hypothalamic...
