Anduaga AM, Nagy D, Costa R, Kyriacou CP. Journal of Insect Physiology 2018 Unlike many insects where photoperiod per se induces diapause, reproductive arrest in Drosophila melanogaster adult females is observed at colder temperatures and can be enhanced by shorter photoperiods. Traditional experimental protocols raise flies at 25°C from the larval stage and then the adults are placed at […]
Biscontin A, Wallach T, Sales G, Grudziecki A, Janke L, Sartori E, Bertolucci C, Mazzotta G, De Pittà C, Meyer B, Kramer A, Costa R. Scientific Reports 2017 Antarctic krill (Euphausia superba) is a key species in Southern Ocean ecosystem where it plays a central role in the Antarctic food web. Available information supports the existence of an endogenous timing […]
Inverse European Latitudinal Cline at the timeless Locus of Drosophila melanogaster Reveals Selection on a Clock Gene: Population Genetics of ls-tim.
Zonato V, Vanin S, Costa R, Tauber E, Kyriacou CP. J Biol Rhythms. 2017 The spread of adaptive genetic variants in populations is a cornerstone of evolutionary theory but with relatively few biologically well-understood examples. Previous work on the ls-tim variant of timeless, which encodes the light-sensitive circadian regulator in Drosophila melanogaster, suggests that it may […]
Allebrandt K, Teder-Laving M, Cusumano P, Frishman G, Levandovski R, Ruepp A, Hidalgo M, Costa R, Metspalu A, Roenneberg T, de Pittà C. Scientific Reports Recognizing that insights into the modulation of sleep duration can emerge by exploring the functional relationships among genes, we used this strategy to explore the genome-wide association results for […]
Sales G, Deagle BE, Calura E, Martini P, Biscontin A, De Pittà C, Kawaguchi S, Romualdi C, Meyer B, Costa R, Jarman S. PLoS One Abstract Antarctic krill (Euphausia superba) is a key species in the Southern Ocean with an estimated biomass between 100 and 500 million tonnes. Changes in krill population viability would have […]
Drosophila circadian rhythms in seminatural environments: Summer afternoon component is not an artifact and requires TrpA1 channels.
Green EW, O’Callaghan EK, Hansen CN, Bastianello S, Bhutani S, Vanin S, Armstrong JD, Costa R, Kyriacou CP. Proceeding of the National Academy of Sciences Abstract Under standard laboratory conditions of rectangular light/dark cycles and constant warm temperature, Drosophila melanogaster show bursts of morning (M) and evening (E) locomotor activity and a “siesta” in the […]
Montelli S, Mazzotta G, Vanin S, Caccin L, Corrà S, De Pittà C, Boothroyd C, Green EW, Kyriacou CP, Costa . Journal of biological rhythms Abstract Previous analysis of Drosophila circadian behavior under natural conditions has revealed a number of novel and unexpected features. Here we focus on the oscillations of per and tim mRNAs […]
Nucleotide excision repair efficiency in quiescent human fibroblasts is modulated by circadian clock.
Bee L, Marini S, Pontarin G, Ferraro P, Costa R, Albrecht U, Celotti L. Nucleic Acids Research Abstract The efficiency of Nucleotide Excision Repair (NER)process is crucial for maintaining genomic integrity because in many organisms, including humans, it represents the only system able to repair a wide range of DNA damage. The aim of the […]
Mazzotta G, Rossi A, Leonardi E, Mason M, Bertolucci C, Caccin L, Spolaore B, Martin AJ, Schlichting M, Grebler R, Helfrich-Förster C, Mammi S, Costa R, Tosatto SC. Proceeding of the National Academy of Sciences Abstract Cryptochromes are flavoproteins, structurally and evolutionarily related to photolyases, that are involved in the development, magnetoreception, and temporal organization […]
Menegazzi P, Vanin S, Yoshii T, Rieger D, Hermann C, Dusik V, Kyriacou CP, Helfrich-Förster C, Costa R. Journal of biological rhythms Abstract The circadian clock modulates the adaptive daily patterns of physiology and behavior and adjusts these rhythms to seasonal changes. Recent studies of seasonal locomotor activity patterns of wild-type and clock mutant fruit […]
