Analysis of brain of Canton-S females deprived of sleep by perturbations during their normal sleep period. Perturbation effect also assessed during their active period to control for its effect during sleep deprivation. Results suggest processes altered during prolonged wakefulness and during sleep.

(Submitter supplied) To gain insight into the dynamic molecular processes that are altered during prolonged wakefulness and during sleep. We performed an RNA expression profiling study examining temporal changes in the brain of Drosophila in relationship to the duration of prior sleep or wakefulness. Our experimental design allowed us to determine whether genes identified as differentially regulated between sleep and wakefulness were up- or down-regulated in these states. more...

(Submitter supplied) Although the specific functions of sleep have not been completely elucidated, the literature has suggested that sleep is essential for proper homeostasis. Sleep loss is associated with changes in behavioral, neurochemical, cellular, and metabolic function as well as impaired immune response. We evaluated the gene expression profiles of healthy male volunteers who underwent 60 hours of prolonged wakefulness (PW) followed by 12 hours of sleep recovery (SR) using high-resolution microarrays. more...

(Submitter supplied) I hypothesized that social interactions, such as those involved in reproductive behaviors, would lead to immediate and assayable changes in gene expression that may have important effects on individual reproductive success and fitness through alterations in physiology or via short-term or long-term changes in nervous system function.

(Submitter supplied) The sleep-wake cycle is determined by a circadian and a sleep homeostatic process. However, the molecular impact of these two processes and their interaction on different cell populations in the brain remain unknown. To fill this gap, we have profiled the single-cell transcriptome of adult fruit fly brains across the sleep-wake cycle and different circadian times. We show cell type-specific transcriptomic changes between sleep/wakefulness states, different levels of sleep drive, and varying circadian times, with glial cells displaying the largest variations. more...

(Submitter supplied) We monitored gene expression and chromatin accessibility in the cerebral cortex of 10-12 week-old male C57BL/6J mice for 24 hours before and until 48 hours after the end of a single total sleep deprivation (SD) episode. The aim was to characterise the response to SD and recovery thereafter.

(Submitter supplied) To gain insight into the molecular changes of sleep need, this study addresses gene expression changes in a subpopulation of neurons selectively activated by sleep deprivation. Whole brain expression analyses after 6h sleep deprivation clearly indicate that Homer1a is the best index of sleep need, consistently in all mouse strains analyzed. Transgenic mice expressing a FLAG-tagged poly(A)-binding protein (PABP) under the control of Homer1a promoter were generated. more...

(Submitter supplied) These studies adress differential changes in gene expression between sleep deprived and control mice. We profiled gene expression at four time points across the 24H Light/Dark cycle to take into account circadian influences and used three different inbred strains to understand the influence of genetic background.

(Submitter supplied) Why we sleep is still one of the most perplexing mysteries in biology. Strong evidence, however, indicates that sleep is necessary for normal brain function and that the need to sleep is a tightly regulated process. Surprisingly molecular mechanisms that determine the need to sleep are incompletely described. Moreover, very little is known about transcriptional changes that specifically accompany the accumulation and discharge of sleep need. more...

(Submitter supplied) We previously found a short sleeper mutant, fmn, and identified its mutation in the dopamine transporter gene. In an attempt to discover additional sleep related genes in Drosophila, we carried out a microarray analysis comparing mRNA expression in heads of fmn and control flies and found differentially expressed genes. Next, using the pan-neuronal Gal4 driver elav-Gal4 and UAS-RNA interference (RNAi) to knockdown individual genes, we performed a functional screen. more...

(Submitter supplied) To investigate gene expression changes in Drosophila head tissues during social isolation, we performed RNA-sequencing on fruit fly head samples obtained from male flies that have been group-reared for 7 days (Grp), isolated (single-housed) for 7 days (Iso7) and isolated (single-housed) for only 1 day (Iso1). Using differential gene expression analysis, we found a group of candidate genes that are specific to chronic social isolation: they exhibited significant gene expression change in both comparisons of “Grp vs Iso1” and “Iso1 vs Iso7”.

(Submitter supplied) Our objective was to determine whether gene expression in Drosophila melanogaster selectively bred for long or short night sleep duration changes detectably across generations. To meet this objective, we performed transcriptional profiling of ten pooled whole adult individuals from four selected populations and two control populations across 13 generations. We quantified differential expression among selection scheme (long sleep, short sleep, or unselected control), generation (generation 0; then generations 2-13), and sex for each gene.
