MetabolomicsChronic sleep loss sensitizes Drosophila melanogaster to nitrogen stress

Chronic sleep loss profoundly impacts metabolic health and shortens lifespan, but studies of the mechanisms involved have focused largely on acute sleep deprivation. To identify metabolic consequences of chronically reduced sleep, we conducted unbiased metabolomics on heads of three adult Drosoph...

MetabolomicsLeveraging the Metabolic Fingerprint of Sleep Deprivation and Sleep Restriction for Forensic Applications: A Machine Learning Study in Oral Fluid Metabolomics

As sleep loss leads to accidents and impaired safety, a direct metabolic marker would be beneficial for forensic interpretation.

In a sufficiently powered, randomized, controlled, crossover trial under realistic conditions, we examined the salivary metabolome of 20 young men (habitual slee...

TranscriptomicsExpression data from sleep deprivation experiment in mouse hippocampus
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 ...

MetabolomicsExploring the Impact of Sleep Deprivation on the Characteristics and Associations of Oral-Gut Microbiota in Adolescents with Comorbidity of Dental Caries and Obesity
We conducted a cross-sectional study involving 85 adolescents aged 12–15 years, divided into healthy controls (HC), caries-obesity comorbidity (CO), and caries-obesity with sleep deprivation (COS) groups. Oral and fecal samples were collected for 16S rRNA gene sequencing, untargeted metabolomics, an...

TranscriptomicsTranscription profiling of mouse brain during spontaneous sleep and prolonged wakefulness
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 comparin...

TranscriptomicsThe Influence of Sleep Deprivation on Hippocampal CA1 Gene Expression: Relation to Stress and Aging
Sleep deprivation (SD) in young adults is associated with metabolic, stress and cognitive responses that are also characteristic of brain aging. Given that sleep architecture changes with age, including increased fragmentation and decreased slow wave activity, it seems reasonable to investigate pote...

TranscriptomicsEpigenomic profiling in visceral white adipose tissue of offspring of mice exposed to late gestational sleep fragmentation
Background: Late gestational sleep fragmentation (LG-SF) is one of the major perturbations associated with sleep apnea and other sleep disorders during pregnancy. Objectives: To investigate the effects of late LG-SF on the epigenome of visceral white adipose tissue (VWAT) in the offspring. Methods: ...

TranscriptomicsTranscription profiling of mouse brain from 3 inbred strains after sleep deprivation
This SuperSeries is composed of the following subset Series:; GSE9441: The effect of sleep deprivation on gene expression in the brain and the liver of three inbred mouse strains; GSE9442: Molecular correlates of sleep deprivation in the brain of three inbred mouse strains in an around-the-clock exp...

TranscriptomicsTranscription profiling of mouse brain Homer1a-expressing cells after sleep deprivation
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, c...

TranscriptomicsEffect of 12 hour sleep restriction on the transcriptome of mice carying a human Per3 polymorphism
In humans, a primate-specific variable-number tandem-repeat (VNTR) polymorphism (4 or 5 repeats 54 nt in length) in the circadian gene PER3 is associated with differences in sleep timing and homeostatic responses to sleep loss. We investigated the effects of this polymorphism on circadian rhythmicit...
