Project description:Next Generation Sequencing (NGS) was carried out on subjects who visited an oriental medicine clinic due to recurrent sleep disturbance, and 40 individuals (17 male and 23 female) were set as the sleep diorder (SD) group based on their scores on the sleep distrurbance questionnaire of Pittsburgh sleep quality index (PSQI). The control group consisted of 40 healthy individuals (20 males and females each), as assessed by both subjective diagnosis and test for metabolic syndrome factors.Ten individuals (five males and females each) from the SD and the control group, respectively, were allocated for NGS analysis.

Project description:Genome wide DNA methylation profiling of obstructive sleep apnea (OSA) patients and healthy subjects. The Illumina Infinium 27k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 27,000 CpGs in peripheral blood mononuclear cell samples. Samples included 8 normal subjects and 16 patients with obstructive sleep apnea syndrome.

Project description: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: Time-pregnant mice were exposed to LG-SF or control sleep (LG-SC) conditions during the last 6 days of gestation. We performed large-scale DNA methylation analyses using MeDIP coupled to microarrays (MeDIP-chip) in VWAT of 24-week-old LG-SF and LG-SC offspring (n=8 mice/group). Univariate multiple-testing adjusted statistical analyses were applied to identify differentially methylated regions (DMRs) between the groups. DMRs were mapped to their corresponding genes, and tested for potential overlaps with biological pathways and gene networks. Results: We detected 2148 DMRs between LG-SF and LG-SC groups (p< 0.0001, MAT algorithm). A large proportion of the DMR-associated genes have reported functions that are altered in obesity and metabolic syndrome. Overrepresented pathways and gene networks were related to metabolic regulation and inflammatory response. Conclusions: Our findings show a major role for epigenomic regulation of pathways associated to metabolic processes and inflammatory response in VWAT. Furthermore, LG-SF-induced epigenetic alterations appear to increase the susceptibility to obesity and metabolic syndrome in the offspring. 16 mouse VWAT samples were analyzed by MeDIP coupled to microarray analysis: Offspring of mothers exposed to late-gestational sleep fragmentation (n=8, LG-SF group) and offspring of mothers mouse exposed to normal sleep conditions (n=8, LG-SC group)

Project description:22 healthy volunteers without sleep disorders were resident in an environmental scheduling facility and participated in a forced-desynchrony protocol, in which the sleep-wake cycle and the associated fasting-feeding cycle is scheduled to a 28-hour period, of which one third (i.e. 9h 20min) is scheduled for sleep. Under these conditions, during which light levels in the waking episode are kept low and sleep is scheduled in darkness, the phase of the melatonin rhythm occurred at approximately the same clock time during the first (D1) and fourth (D4) 28-h cycle and there were no major changes in either the amplitude or the waveform of this rhythm. During D1 and D4 7 blood samples were taken, RNA was extracted from leukocytes, labelled and hybridised to human whole-genome microarrays A total of 287 samples comprising 22 human subjects, for which 14 samples across multiple time-points/sleep condition were collected.

Project description:To address whether changes in gene expression in blood cells with sleep loss are different in individuals resistant and sensitive to sleep deprivation (SD). Blood draws every 4 hours during a 3-day study: 24-hour normal baseline, 38 hours of continuous wakefulness and subsequent recovery sleep, for a total of 19 time-points per subject, with every 2-hr psychomotor vigilance test (PVT) assessment when awake. Fourteen subjects who were previously identified as behaviourally resistant (n=7) or sensitive (n=7) to SD by PVT. Intervention consisted of 38 hours continuous wakefulness. We found 4,481 unique genes with a significant 24-hour diurnal rhythm during a normal sleep-wake cycle in blood (false discovery rate [FDR] <5%). Biological pathways were enriched for biosynthetic processes during sleep. After accounting for circadian effects, two genes (SREBF1 and CPT1A, both involved in lipid metabolism) exhibited small, but significant, linear changes in expression with the duration of SD (FDR<5%). The main change with SD was a reduction in the amplitude of the diurnal rhythm of expression of normally cycling probe sets. This reduction was noticeably higher in behaviourally resistant subjects than sensitive subjects, at any given p-value. Furthermore, blood cell type enrichment analysis showed that the expression pattern difference between sensitive and resistant subjects is mainly found in cells of myeloid origin, such as monocytes. Individual differences in behavioural effects of sleep deprivation are associated with differences in diurnal amplitude of gene expression for genes that show circadian rhythmicity.

Project description:Eleven healthy human subjects were enrolled in a 6-day simulated shift work protocol. Blood samples were collected during the two 24-hour measurement periods. Blood samples were collected every 4 hours during both measurement periods. Subjects entered the lab on Day 1. At the start of Day 2, the first 24-hour measurement period was started. Subjects slept according to their habitual sleep/wake schedule, followed by a 16-hour constant posture procedure. On days 3-6, the sleep period was delayed by 10 hours. Participants in the control group were exposed to dim light throughout the waking periods; participants in the bright group were exposed to bright light (~6,000lux) for 8 hours during the waking period. Following the third night on this schedule, subjects underwent another 24-hour measurement period. During both measurement periods, blood samples were collected and PBMCs were isolated. mRNA was extracted, labelled, and hybridized to microarrays.

Individual differences in behavioural effects of sleep deprivation are associated with differences in diurnal amplitude of gene expression for genes that show circadian rhythmicity. Blood draws were done every 4 hours during a 3-day (+1 baseline day) study: 24-hour normal baseline (6 time points: day 1 8hr, 12hr, 16hr, 20hr, day 2 0hr, 4hr), 38 hours of continuous wakefulness (10 time points: day 2 8hr, 12hr, 16hr, 20hr, day 3 0hr, 4hr, 8hr, 12hr, 16hr, 20hr) and subsequent recovery sleep (3 time points: day 4 0hr, 4hr, 8hr), for a total of 19 time-points per subject, with every 2-hr psychomotor vigilance test (PVT) assessment when awake. The missing/failed samples were as following: Resistant subjects (total 10 samples): BH006 day 2 20hr, 12hr, BH003 day 2 12hr, 4hr, BH003 day 3 4hr, BH008 day 4 0hr, BH008 day 1 16hr, BH008 day 3 16hr 20hr, BH010 day 4 0hr; Sensitive subjects (total 7 samples): BH004 day 2 12hr and 1 more missing sample, BH026 day 2 4hr, BH007 day 2 20hr and 1 more missing sample, BH016 day 2 4hr, BH015 day 3 0hr.
