Changes in total RNA in BK deficient mice after 4h sleep deprivation [individuals]

Project description:Animals deficient for the alpha subunit of the large conductance calcium dependent potassium channel (BK) were sleep deprived for 4 hours and compared to wildtype littermates as well as animals (wildtype littermate and BK deficient) left undisturbed for the same time.

Microglia protect memories formed during sleep deprivation

Project description:Purpose: To determine the specific effects of 6 hours sleep deprivation after a learning event on the transcriptomes of microglia. Sleep deprivation can generate inflammatory responses in the neuronal environment. In turn, this inflammation increases sleep drive, leading to a rebound in sleep duration. Microglia, a type of support cell found exclusively in the brain, have previously been found to release of inflammatory signals and exhibit altered characteristics in response to sleep deprivation. Together, this suggests microglia may be partially responsible for the brain’s response to sleep deprivation through their inflammatory activity. In this study, we fully and selectively ablated microglia from the mouse brain and assessed resulting sleep, circadian, and sleep deprivation phenotypes. We find microglia are dispensable for both homeostatic sleep and circadian function and the sleep rebound response to sleep deprivation. However, we uncover a phenomenon by which microglia appear to be essential for the protection of synapses and associated memories formed during a period of sleep deprivation, further expanding the list of known functions for microglia in synaptic modulation.

Altered hippocampal transcriptome dynamics following sleep deprivation

Project description:Purpose: To comprehensively identify the gene expression changes that occur after acute sleep deprivation. Method: We performed total RNA sequencing after 5hours of sleep deprivation. Results: Using total RNA-sequencing, we show that acute sleep deprivation causes dramatic gene expression changes in the mouse hippocampus. Conclusion: This study provides insight into the biological impact of acute sleep deprivation.

Epigenomics of Total Acute Sleep Deprivation in Relation to Genome-wide DNA Methylation Profiles and RNA Expression

Project description:Despite an established link between sleep deprivation and epigenetic processes in humans, it remains unclear to what extent sleep deprivation modulates DNA methylation. We performed a within subject randomized blinded study with 16 healthy subjects to examine the effect of one night of total acute sleep deprivation (TSD) on the genome wide methylation profile in blood compared to normal sleep. Genome-wide differences in methylation between both conditions were assessed by applying a paired regression model that corrected for monocyte subpopulations (neutrophil/leukocyte ratio). Additionally, the correlations between the methylation of genes detected to be modulated by TSD and gene expression were examined in a separate, publicly available cohort of ten healthy male donors (E-GEOD-49065). Sleep deprivation significantly affected the DNA methylation profile both independently and in dependency of shifts in monocyte composition. Our study detected differential methylation of 269 probes. Notably, one CpG site was located 69bp upstream of ING5, which has been shown to be differentially expressed following sleep deprivation. Gene set enrichment analysis detected the Notch and Wnt signaling pathways to be enriched among the differentially methylated genes. These results provide evidence that total acute sleep deprivation alters the methylation profile in healthy human subjects. This is, to our knowledge, the first study that systematically investigated the impact of total acute sleep deprivation on genome-wide DNA methylation profiles in blood and related the epigenomic findings to the expression data.

Sleep Deprivation and Recovery Sleep for 7 Regions of Mouse Brain.

Project description:Analysis of the effects of sleep deprivation, recovery sleep, and three time-of-day controls on seven brain regions laser microdissected from mouse brain. The regions include the locus coeruleus, suprachiasmatic nucleus, hypocretin area, tuberomammillary nucleus, orbital cortex, posteromedial cortical amygdala, and entorhinal cortex. In this study, 7 brain regions were collected by laser microdissection from brain tissue of mice from 5 different treatment groups and used for microarray experiments. Four biological replicates were generated for each regionxcondition. Conditions are: SD, sleep deprivation for 6 hours from ZT0 - 6; SDC, time-of-day control for SD at ZT6; RS, recovery sleep for 4 hours following SD; RSC, time-of-day control for RS at ZT10; W, spontaneous waking at ZT18.

Transcriptional dynamics of sleep deprivation and subsequent recovery sleep in the murine 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.
