Natural alleles of the clock gene timeless differentially affect life-history traits in Drosophila
Andreatta G, Montagnese S, Costa R Front Physiol Circadian clocks orchestrate a variety of physiological and behavioural functions within the 24-h day. These timekeeping systems have also been implicated in developmental and reproductive processes that span more (or less) than 24 h. Whether natural alleles of cardinal clock genes affect entire sets of life-history traits […]
Circadian rhythms and the liver
Costa R, Mangini C, Domenie E, Zarantonello L, Montagnese S Liver Int This narrative review briefly describes the mammalian circadian timing system, the specific features of the liver clock, also by comparison with other peripheral clocks, the role of the liver clock in the preparation to food intake, and its relationship with energy metabolism. It […]
Keeping an eye on circadian time in clinical research and medicine
Klerman EB, Brager A, Carskadon MA, Depner CM, Foster R, Goel N, Harrington M, Holloway PM, Knauert MP, LeBourgeois MK, Lipton J, Merrow M, Montagnese S, Ning M, Ray D, Scheer FAJL, Shea SA, Skene DJ, Spies C, Staels B, St-Onge MP, Tiedt S, Zee PC, Burgess HJ Clin Transl Med Background: Daily rhythms are […]
Hyperammonaemia disrupts daily rhythms reversibly by elevating glutamate in the central circadian pacemaker
Granados-Fuentes D, Cho K, Patti GJ, Costa R, Herzog E D, Montagnese S Liver Int Patients with cirrhosis exhibit features of circadian disruption. Hyperammonaemia has been suggested to impair both homeostatic and circadian sleep regulation. Here, we tested if hyperammonaemia directly disrupts circadian rhythm generation in the central pacemaker, the suprachiasmatic nuclei (SCN) of the […]
Driving simulator performance worsens after the Spring transition to Daylight Saving Time
Orsini F, Zarantonello L, Costa R, Rossi R, Montagnese S iScience Circadian desynchrony and sleep deprivation related to the Spring transition to Daylight Saving Time (DST) have been associated with several unfavorable outcomes, including an increase in road traffic accidents. As previous work has mainly focused on analyzing historical crash/hospitalization data, there is virtually no literature […]
