Project description:Study objectives: Acute sleep deprivation affects both central and peripheral biological processes. Prior research has mainly focused on specific proteins or biological pathways that are dysregulated in the setting of sustained wakefulness. This pilotexploratory study’s objective wasaimed to provide a comprehensive view of the biological processes and proteins impacted by acute sleep deprivation in both plasma and cerebrospinal fluid (CSF). Methods: We collected plasma and CSF from human participants during one night of sleep deprivation and control normal sleep conditions. 1300 proteins were measured at hour 0 and hour 24 using a high-scale aptamer-based proteomics platform (SOMAomascan) and a systematics biological database tool (Metascape) was used to reveal dysregulated biological pathways. Results: Acute sleep deprivation lead to opposite effects in plasma and CSF, decreasingdecreased the number of upregulated and downregulated differential protein expression and biological pathways and proteins in plasma but increased upregulated and downregulated protein and biological pathwayssing them in CSF. Predominantly affected pProteins and n pathways were associated with that were predominantly affected by sleep deprivation included immune response, inflammation, phosphorylation, membrane signaling, cell-cell adhesion, and extracellular matrix organization. Conclusions: The identified modification across biofluids adds to evidence that acute sleep deprivation has important impacts on biological pathways and proteins that can negatively affect human health. As a hypothesis-driving study, these findings may help with the exploration of novel mechanisms that mediate sleep loss and associated conditions, drive the discovery of new sleep loss biomarkers, and ultimately aid in the identification of new targets for intervention to human diseases.

Project description:Sleep is an evolutionarily conserved physiological process implicated in the consolidation of learning and memory. In our study, sleep deprivation-induced cognitive deficits in zebrafish are mediated through reduction in glucose metabolism to the hexosamine biosynthetic pathway. Therefore, we perform the microarray to confirm glucose metabolic pathway- and nerve system-related genes expression using mRNA from brains of control, sleep-deprived and fear-conditioned zebrafish groups.

Project description:We used microarrays to detail the global programme of gene expression underlying the effect of sleep deprivation in the mouse hippocampus and identified distinct classes of regulated genes during this process. Hippocampal tissue was taken from sleep deprived mice and time-matched non-sleep-deprived control animals that were left undisturbed in their home cages during the sleep deprivation period for a total of 8 and 9 replicates per group. RNA was isolated and cDNA was synthesized from hippocampal tissue, and the sample from each animal was hybridized to a separate Affymetrix Mouse 430_2 microarray

Project description: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. In this study we present an integrated 2 cross-laboratory analysis of the effects of sleep deprivation (SD) in gene expression in the mouse cortex. We also evaluate changes in gene expression genome-wide following various lengths of subsequent recovery sleep. (RS). We demonstrate that changes in gene expression specifically linked to SD or RS, and not to technical factors (e.g. the assay used), requires a novel analysis methodology not previously utilized in the field of sleep research. Cortical samples from mice were analyzed, from groups that were sleep deprived, sleep deprived and allowed to recover for 1, 2, 3, or 6 hours, and circadian control animals that were not sleep deprived. The experimental protocol began at lights on (ZT0) with 13 mice: 1 sacrificed, 4 control mice left undisturbed, and 8 mice kept awake with gentle brushing when attempting to sleep. After 5 hours of sleep deprivation the mice were randomly assigned to recovery sleep or continued sleep deprivation, and at fixed intervals the mice were sacrificed, dissected and the left cortex retained. The experimental protocol was repeated 7 times, one animal per timepoint per experimental day, so that 7 independent experiments are represented for each timepoint. All animals were acclimated to the brushing and tapping on cages used during sleep deprivationfor 6 days, and dissections and tissue collection were performed by a single experimenter.

Project description:Although at the organismal level sleep is defined as a behavioral state, at the level of the cerebral cortex sleep has a distinct local and use-dependent aspect. This observation raises the question whether sleep is a functional property of a complex brain or occurs at the level of neuronal assemblies with populations that were active more during wakefulness needing more intense sleep to recover. Here we show that primary cortical cultures have the capacity to change between sleep- and wake-like states that share key signatures with their in vivo counterparts. Cortical cultures initially exhibit random firing activity that is gradually replaced by a M-bM-^@M-^\sleep-likeM-bM-^@M-^] synchronized burst-pause firing activity as neurons mature and make connections. When stimulated with excitatory neurotransmitters, transient tonic firing is observed, followed by the reappearance of a M-bM-^@M-^\sleep-likeM-bM-^@M-^] state. Besides electrophysiological similarities also the transcriptional profile of stimulated cortical cultures greatly resembles that of the cortex of sleep deprived animals. We then used our in vitro model to map the metabolic pathways activated by the M-bM-^@M-^\wake-likeM-bM-^@M-^] state and found evidence for increased lysolipid release, strongly suggesting that sleep plays a role in neuronal membrane homeostasis. With our in vitro model the cellular and molecular consequences of sleep loss and the genetic determinants of disturbed sleep can now be investigated in a dish. Keywords: stress response For the in vivo transcriptome analyses mice were sleep deprived for 6 hours and brain harvested immediately afterwards. For the in vitro analyses, cortical cultures were stimulated with a neurotransmitter cocktail and cells harvested 3 hours afterwards. Control mice were kept undisturbed in their home cage and control cultures were sham stimulated with water. Also, another set of sleep deprived mice as well as stimulated cultures were allowed to recover before being sampled the next day at the time of day at which sleep deprivation or stimulation started the day before).

Project description:These studies address temporal changes in gene expression during spontaneous sleep and extended wakefulness in the mouse cerebral cortex, a neuronal target for processes that control sleep; and the hypothalamus, an important site of sleep regulatory processes. We determined these changes by comparing expression in sleeping animals sacrificed at different times during the lights on period, to that in animals sleep deprived and sacrificed at the same diurnal time.
