(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) Purpose: After identifying a difference in the response to sleep deprivation between the morning and evening, we assayed gene expression in a key homeostatic circuit in the Drosophila brain: the R5 ellipsoid body neurons. We sought to identify changes in gene expression in this circuit that are critical for the behavioral output. Methods: Flies expressing GFP via a restrictive R5 driver were entrained to a 12:12 light:dark paradigm at 25C. more...

(Submitter supplied) To address whether changes in gene expression in blood cells with sleep loss are different in individuals resistant and sensitive to sleep deprivation (SD). Blood draws every 4 hours during a 3-day study: 24-hour normal baseline, 38 hours of continuous wakefulness and subsequent recovery sleep, for a total of 19 time-points per subject, with every 2-hr psychomotor vigilance test (PVT) assessment when awake. more...

(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...

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) 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) Here, we investigated the role of EphA4 in the molecular response to sleep deprivation by measuring forebrain gene expression in EphA4 KO mice. More precisely, we measured the effect of the mutation and of a 6-h sleep deprivation on genome-wide forebrain gene expression using microarray.

(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) 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) The molecular mechanisms governing sleep are largely unknown. Here, we used a combination of single-cell RNA sequencing to interrogate the molecular and functional underpinnings of sleep. Different cell types in three important brain regions for sleep (brainstem, cortex and hypothalamus) had a similar transcriptional response to sleep need, with a large proportion of cells changing during recovery sleep. more...
