Analysis of heads of Canton-S males subjected to social isolation (single-housed). Social experience with conspecifics is an environmental influence on aggressiveness common to many species. Results provide insight into the molecular basis of the effect of social experience on aggressiveness.

(Submitter supplied) Social experience influences multiple behaviors of many animal species, including aggression. Social isolation often increases aggressiveness. To investigater the molecular basis of social influences on aggressiveness, we performed comparative gene expression profiling on heads from 6-day-old, single-housed, more aggressive and group-housed, less aggressive male flies.

(Submitter supplied) Modulation of action choices according to the environmental context is crucial for animal survival and reproductive success1. Aggression, despite its general importance as a social behavior2, can become detrimental if uncontrolled3,4. However, the genetic and neural basis for aggression control through active suppression remains largely unknown. Here we found nvy, a Drosophila homolog of vertebrate myeloid translocation gene (MTG)5 involved in transcriptional regulation6-8, suppresses aggression through a specific subset of neurons. more...

(Submitter supplied) Purpose: The goal of this study was to globally characterize the transcript levels of genes in Drosophila photoreceptor neurons. Using transcriptome profiling of isolated photoreceptor nuclei from day 10 flies, we identified genes with enriched or reduced transcript levels post nuclei isolation relative to the starting pre-isolation material (whole head RNA extracts).

(Submitter supplied) Purpose: The goal of this study was to globally characterize the transcript levels of genes in Drosophila photoreceptor neurons during aging. Using transcriptome profiling of isolated photoreceptor nuclei we analyzed the changes in gene expression that occur during aging over 5 time-points from 10 to 40 days post-eclosion and identified sets of genes with both up-regulated and down-regulated expression.

(Submitter supplied) We generated 4 separate subpopulations of selected flies from 1 starting population of a mixture of Canton-S flies. Two of the populations (AggrI and AggrII) were selected for increased aggression by picking males from a population cage that engaged in the most intense fighting (known as escalation behavior). Thirty males were selected every generation (from a total of 120 males per cage) per line and mated with random virgin females from that same generation. more...

(Submitter supplied) Circadian clocks are temporally aligned to the environment via signals, or Zeitgebers, such as daily light and temperature cycles, food availability, and social behavior. In this study, we show that genome-wide expression profiles from temperature-entrained flies show a dramatic difference in the presence or absence of a thermocycle. Whereas transcription appears to be modified globally by changes in temperature, there is a specific set of transcripts that continue to oscillate in constant conditions following temperature entrainment. more...
