Project description:Sleep Deprivation and Recovery Sleep for 7 Regions of Mouse Brain.

Project description: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. Because PABP binds the poly(A) tails of mRNA, affinity purification of FLAG-tagged PABP proteins from whole brain lysates, is expected to co-precipitate all mRNAs from neurons expressing Homer1a. Three other activity-induced genes (Ptgs2, Jph3, and Nptx2) were identified by this technique to be over-expressed after sleep loss. All four genes play a role in recovery from glutamate-induced neuronal hyperactivity. The consistent activation of Homer1a suggests a role for sleep in intracellular calcium homeostasis for protecting and recovering from the neuronal activation imposed by wakefulness. Experiment Overall Design: Experiments were performed on male mice, 12 weeks of age +/- 1 week. Animals were housed in polycarbonate cages (31x18x18cm) in an experimental room with an ambient temperature varying from 23° to 25°C under a 12:12 hrs light/dark cycle. Food and water were available ad libitum. At light onset mice were either sleep deprived by gentle handling (n=10) or left undisturbed (n=10) for 6 hrs. Animals were then randomly sacrificed by cervical dislocation. Total RNA from the whole brain was isolated for control (n=4) and sleep deprived (n=4) using a commercial RNA extraction kit (RNeasy Lipid Tissue Kit, Quiagen). Specific Homer1a-expressing cells polyA RNAs were immunoprecipitated following the total brain crosslinking (1% formaldehyde perfusion) for sleep deprived (n=6) and control (n=6) animals. The total RNA from the pull-down supernatants were also harvested (n=4). To test for transcriptional changes after sleep deprivation Homer1a-expressing cells, we proceeded in 2 steps: (1) identify probe sets enriched in the pull-down extracts, (2) among those probe sets compare sleep deprivation to control condition in both pull-down (6 vs. 6 chip comparison) and whole-brain (4 vs. 4 chip comparison) extracts. 4728 probe sets were significantly enriched at 5% FDR when pull-downs were compared to both supernatant and whole-brain extracts.

Project description:Micro-RNAs (miRNAs) are key, post-transcriptional regulators of gene expression that have been implicated in a plethora of biological processes. Their role in sleep, however, has received little attention. We first investigated the effects of sleep deprivation on the brain miRNA transcriptome. Sleep deprivation affected 52 miRNAs in the whole brain, and particularly miR-709, an activity-dependent microRNA, enriched in the cerebral cortex.

Project description:Sleep loss regulates gene expression throughout the brain and impacts learning and memory. However, the molecular consequences of sleep deprivation and the ability of subsequent sleep (recovery sleep) to restore baseline gene expression remain underexplored. Our goal here is to overview transcriptional changes at the gene level in the cortex of adult male wildtype mice in response to sleep loss and recovery sleep. This dataset constitutes an integration of novel data with two publicly available RNA-seq studies and contains 3, 5, and 6 hours of sleep deprivation and 2 and 6 hours of recovery sleep time points.
