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.

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: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.

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: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:Every day, we sleep for a third of the day. Sleep is important for cognition, brain waste clearance, metabolism, and immune responses. Homeostatic regulation of sleep is maintained by progressively rising sleep need during wakefulness, which then dissipates during sleep. The molecular mechanisms governing sleep are largely unknown. Here, we used a combination of single-cell RNA sequencing and cell-type specific proteomics to interrogate the molecular and functional underpinnings of sleep. Different cell-types in the brain regions show similar transcriptional response to sleep need whereas sleep deprivation changes overall expression indicative of altered antigen processing, synaptic transmission and cellular metabolism in brainstem, cortex and hypothalamus, respectively. Increased sleep need enhances expression of transcription factor Sox2, Mafb, and Zic1 in brainstem; Hlf, Cebpb and Sox9 in cortex, and Atf3, Fosb and Mef2c in hypothalamus. Results from cell-type proteome analysis suggest that sleep deprivation changes abundance of proteins in cortical neurons indicative of altered synaptic vesicle cycles and glucose metabolism whereas in astrocytes it alters the abundance of proteins associated with fatty acid degradation. Similarly, phosphoproteomics of each cell type demonstrates large shifts in site-specific protein phosphorylation in neurons and astrocytes of sleep deprived mice. Our results indicate that sleep deprivation regulates transcriptional, translational and post-translational responses in a cell-specific manner and advances our understanding of the cellular and molecular mechanisms that govern sleep-wake homeostasis in mammals.

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.
