Project description:Sleep, a fundamental physiological process occupying approximately one - third of the human lifespan, is essential for maintaining overall health. Acute sleep deprivation (ASD), a prevalent condition in modern society, has been strongly associated with the pathogenesis of various neurodegenerative diseases. Endothelial cells play a pivotal role in regulating vascular tone, modulating inflammatory responses, and maintaining barrier integrity. While previous research has indicated that sleep deprivation can contribute to endothelial cell dysfunction, potentially leading to the development of atherosclerosis, hypertension, and other vascular disorders, the precise effects of ASD on brain endothelial cells and the underlying molecular mechanisms remain incompletely understood. Our study focuses on exploring the specific effects of acute sleep deprivation on the phenotypic characteristics and molecular functions of brain endothelial cells. Through bioinformatics analysis and multiple experimental approaches, it reveals the close relationship between acute sleep deprivation and endothelial cell senescence as well as alterations in molecular functions. By uncovering the molecular change, we provides a theoretical basis and novel perspectives for the research and treatment of related diseases.

Project description:Introduction: Sleep deprivation is associated with increased cardiovascular risk, which is more pronounced in women than men; however, causal evidence is lacking and the underlying mechanisms are unclear. We used randomized crossover design of prolonged sleep deprivation that mimics “life-like conditions” and endothelial cells (ECs) harvested from healthy women to investigate directly whether sleep deprivation impairs endothelial function and to identify underlying mechanisms. Methods: Healthy women with normal habitual sleep (7-9 h/day) were randomly allocated to 6-weeks of adequate sleep (7-9 h/day) or sleep deprivation (1.5 h less than habitual sleep) in a crossover design. Sleep duration was monitored objectively by actigraphy. EC harvesting and brachial artery flow-mediated dilation (FMD) were performed at baseline and the end of adequate sleep and sleep deprivation period. Results: Twenty-eight healthy women (mean [SE] age 35±13 years; BMI 25±3 kg/m2) participated. Compared with adequate sleep, sleep deprivation reduced FMD (mean±SE 8.65±0.48 vs. 7.35±0.39, p=0.02) and increased EC inflammation (nuclear factor-κB nuclear fluorescence area mean±SE 1.36±0.24 vs. 2.04±0.38 μm2, p=0.03 and mRNA expression of vascular cell adhesion molecule-1 mean±SE 1.00±0.19 vs. 2.31±0.72, p=0.04) compared with adequate sleep. Sleep deprivation increased EC oxidative stress by 67% compared with adequate sleep (redox sensitive fluorogenic probe fluorescence intensity, p=0.002) without upregulating antioxidant response. Using RNA-seq and a predicted protein-protein interaction algorithm, we identified reduced expression of serum response factor, a transcription factor that primes cortical response to sleep deprivation, and its endothelial target Defective in Cullin Neddylation-1 Domain Containing 3 as novel mediators of impaired nuclear factor (erythroid-derived 2)-like 2-mediated antioxidant responses in ECs in sleep deprivation. Conclusion: Sleep deprivation impairs clearance of endothelial oxidant stress accumulated during wakefulness leading to endothelial dysfunction and potentially increased cardiovascular risk in women.

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.

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.

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.

Project description:To assess the effect of sleep deprivation on glucose metabolism and elucidate the mechanism, we established the mouse model wth C57BL/6J that is useful for the intervention on sleep deprivation associated diabetes and evaluate the liver metabolism and gene expression. Single six hours sleep deprivation induced increased hepatic glucose production assessed by pyruvate tolerance test and the hepatic triglyceride content was significantly higher in the sleep deprivation group than freely sleeping control group. Liver metabolites such as ketone bodies were increased in sleep deprivation group. Some gene expressions which associated with lipogenesis were increased.

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:Inadequate sleep prevails in modern society and it impairs the circadian transcriptome. However, whether acute sleep deprivation has impact on the circadian rhythms is not clear. Here, we show that in mouse lung, a 10-hour acute sleep deprivation can alter the circadian expression of approximally 3,000 genes. We found that circadian rhythm disappears in genes related to metabolism and signaling pathways regulating protein phosphorylation after acute sleep deprivation, while the core circadian regulators do not change much in rhythmicity. Importantly, the strong positive correlation between mean expression and amplitude (E-A correlation) of cycling genes has been validated in both control and sleep deprivation conditions, supporting the energetic cost optimization model of circadian gene expression. Thus, we reveal that acute sleep deprivation leads to a profound change in the circadian gene transcription that influences the biological functions in lung.
