Sleep timing in flies from “adolescence” to adulthood

Domenie ED, Cusumano P, Montagnese S, Costa R Fly (Austin) The aim of the present study was to assess sleep timing in Drosophila melanogaster at different ages, within the setting of an enforced schedule of varying light-dark stimuli, simulating light exposure variations between four typical office working days and one free day spent outside by a human, for a total of […]

A PDZ scaffolding/CaM-mediated pathway in Cryptochrome signaling

Bellanda M, Damulewicz M, Zambelli B, Costanzi E, Gregoris F, Mammi S, Tosatto SCE, Costa R, Minervini G, Mazzotta GM Protein Sci Cryptochromes are cardinal constituents of the circadian clock, which orchestrates daily physiological rhythms in living organisms. A growing body of evidence points to their participation in pathways that have not traditionally been associated […]

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 […]

Mitochondrial Cytochrome c Oxidase Defects Alter Cellular Homeostasis of Transition Metals

Brischigliaro M, Badocco D, Costa R, Viscomi C, Zeviani M, Pastore P, Fernández-Vizarra E Front Cell Dev Biol The redox activity of cytochrome c oxidase (COX), the terminal oxidase of the mitochondrial respiratory chain (MRC), depends on the incorporation of iron and copper into its catalytic centers. Many mitochondrial proteins have specific roles for the synthesis and […]

Inhibition of the deubiquitinase USP8 corrects a Drosophila PINK1 model of mitochondria dysfunction
