PER1 phosphorylation specifies feeding rhythm in mice.
Organization of circadian behavior, physiology, and metabolism is important for human health. An S662G mutation in hPER2 has been linked to familial advanced sleep-phase syndrome (FASPS). Although the paralogous phosphorylation site S714 in PER1 is conserved in mice, its specific function in circadian organization remains unknown. Here, we find that the PER1S714G mutation accelerates the molecu...
متن کاملEffects of the circadian rhythm gene period 1 (per1) on psychosocial stress-induced alcohol drinking.
OBJECTIVE Circadian and stress-response systems mediate environmental changes that affect alcohol drinking. Psychosocial stress is an environmental risk factor for alcohol abuse. Circadian rhythm gene period 1 (Per1) is targeted by stress hormones and is transcriptionally activated in corticotropin releasing factor-expressing cells. The authors hypothesized that Per1 is involved in integrating ...
متن کاملPhosphorylation of clock protein PER1 regulates its circadian degradation in normal human fibroblasts.
Recent advances suggest that the molecular components of the circadian clock generate a self-sustaining transcriptional-translational feedback loop with a period of approx. 24 h. The precise expression profiles of human clock genes and their products have not been elucidated. We cloned human clock genes, including per1, per2, per3, cry2 and clock, and evaluated their circadian mRNA expression p...
متن کاملThe daily rhythm of mice.
The house mouse Mus musculus represents a valuable tool for the analysis and the understanding of the mammalian circadian oscillator. Forward and reverse genetics allowed the identification of clock components and the verification of their function within the circadian clockwork. In many cases unforeseen links were discovered between a particular circadian regulatory protein and various disease...
متن کاملIn Vivo Monitoring of Multi-Unit Neural Activity in the Suprachiasmatic Nucleus Reveals Robust Circadian Rhythms in Period1−/− Mice
The master pacemaker in the suprachiasmatic nucleus (SCN) controls daily rhythms of behavior in mammals. C57BL/6J mice lacking Period1 (Per1⁻/⁻) are an anomaly because their SCN molecular rhythm is weak or absent in vitro even though their locomotor activity rhythm is robust. To resolve the contradiction between the in vitro and in vivo circadian phenotypes of Per1⁻/⁻ mice, we measured the mult...
