Project description:We used long-oligonucleotide microarrays to investigate whether alternative splicing in Drosophila is regulated in a sex-, stage-, or tissue-specific manner. To examine sex-specific splicing, we compared gene expression profiles of male and female pupae 12 hours after pupariation. To examine stage-specific splicing, we compared expression profiles of mixed-sex, 0-24 hour old embryos and mixed-sex, 12 hour old pupae. To examine tissue-specific splicing, we compared expression profiles of adult male heads and abdomens 24-48 hours after eclosion. To examine tissue-specific splicing, we compared expression profiles of adult male heads and abdomens at 24-48 hours after eclosion. Keywords: tissue-specific expression profiles

Project description:This project investigates rhythmic gene expression in Drosophila melanogaster under different temperature and light conditions. RNA sequencing was performed on adult male fly heads collected every 4 hours over two consecutive days. Samples were collected under constant dark (DD) or light/dark (LD) cycles at 18C, 25C, and 29C. The dataset enables analysis of circadian and temperature-dependent transcriptional regulation in Drosophila.

Project description:<p>Chronic sleep loss profoundly impacts metabolic health and shortens lifespan, but studies of the mechanisms involved have focused largely on acute sleep deprivation. To identify metabolic consequences of chronically reduced sleep, we conducted unbiased metabolomics on heads of three adult Drosophila short-sleeping mutants with very different mechanisms of sleep loss: fumin (fmn), redeye (rye), and sleepless (sss). Common features included elevated ornithine and polyamines, with lipid, acyl-carnitine, and TCA cycle changes suggesting mitochondrial dysfunction. Studies of excretion demonstrate inefficient nitrogen elimination in adult sleep mutants, likely contributing to their polyamine accumulation. Increasing levels of polyamines, particularly putrescine, promote sleep in control flies but poison sleep mutants. This parallels the broadly enhanced toxicity of high dietary nitrogen load from protein in chronically sleep-restricted Drosophila, including both sleep mutants and flies with hyper-activated wake-promoting neurons. Together, our results implicate nitrogen stress as a novel mechanism linking chronic sleep loss to adverse health outcomes-and perhaps for linking food and sleep homeostasis at the cellular level in healthy organisms.</p>

Keywords: tissue-specific expression profiles Drosophila isogenic line WI89 was used. Mixed-sex, mixed-stage embryos were harvested from plates on which females had been allowed to oviposit for 24 hours. To obtain synchronized cohorts of pupae, male and female white prepupae were collected at 0-1 hour after pupariation and aged for 12 hours at 25C. Mixed-sex pupal samples were generated by mixing equal amount of male and female pupal RNA. Adult heads and abdomens were dissected from 24-48 hour old males. mRNA was isolated and labeled without amplification.
