Circadian rhythms of locomotor activity in Drosophila.
Drosophila is by far the most advanced model to understand the complex biochemical interactions upon which circadian clocks rely. Most of the genes that have been characterized so far were isolated through genetic screens using the locomotor activity rhythms of the adults as a circadian output. In addition, new techniques are available to deregulate gene expression in specific cells, allowing t...
متن کاملDrosophila Ebony Activity Is Required in Glia for the Circadian Regulation of Locomotor Activity
Previous studies suggest that glia may be required for normal circadian behavior, but glial factors required for rhythmicity have not been identified in any system. We show here that a circadian rhythm in Drosophila Ebony (N-beta-alanyl-biogenic amine synthetase) abundance can be visualized in adult glia and that glial expression of Ebony rescues the altered circadian behavior of ebony mutants....
متن کاملmiR-124 Regulates the Phase of Drosophila Circadian Locomotor Behavior.
UNLABELLED Animals use circadian rhythms to anticipate daily environmental changes. Circadian clocks have a profound effect on behavior. In Drosophila, for example, brain pacemaker neurons dictate that flies are mostly active at dawn and dusk. miRNAs are small, regulatory RNAs (≈22 nt) that play important roles in posttranscriptional regulation. Here, we identify miR-124 as an important regulat...
متن کاملSocial synchronization of circadian locomotor activity rhythm in the fruit fly Drosophila melanogaster.
Circadian clocks regulate the physiology and behaviour of organisms across a wide range of taxa. To keep track of local time, these clocks use a variety of time cues such as light-dark, temperature, food availability and social interaction cycles. This study assessed the role of social cues in modulating circadian clocks of the fruit fly Drosophila melanogaster. Using pair-wise interactions, we...
متن کاملEffects of altitude on circadian rhythm of adult locomotor activity in Himalayan strains of Drosophila helvetica
BACKGROUND We recently reported that the altitude of origin altered the photic and thermal sensitivity of the circadian pacemaker controlling eclosion and oviposition rhythms of high altitude Himalayan strains of Drosophila ananassae. The present study was aimed at investigating the effects of altitude of origin on the pacemaker controlling the adult locomotor activity rhythm of D. helvetica. ...
