Sample GSM1526444 Query DataSets for GSM1526444
Status Public on Oct 16, 2014
Title AF0139_SR_T5
Sample type RNA
 
Source name Blood_19.5hrsAwake_at01:45afterSleepRestriction_Per3_5\5_genotype
Organism Homo sapiens
Characteristics tissue: Blood
sleepprotocol: Sleep Restriction
genotype: 5\5
hoursawake: 19.5
timesampletaken: 1:45
circadianphase: -3
Treatment protocol 2.5 ml of blood is drawn into the PAXGene tube at each sampling point. The tube is inverted 10 times to mix. The tube is then stored at room temperature for 4 hours in upright position. The tube is transferred to -50°C and placed lying down (never in upright position as this may cause the tube to crack) for storage at the university of Surrey Clinical Research Centre. The tube is transferred on ice to University of Surrey Faculty of Health and Medical Sciences for storage/processing
Growth protocol Blood samples were collected via an indwelling venous cannula sited in the forearm for minimum discomfort and restriction of movement. Cannulae were kept patent by the use of sterile saline. Each sample tube was coded for subject and sample collection time (participant code/sample type/sequential number)
Extracted molecule total RNA
Extraction protocol Total RNA was isolated using a PAXgene Blood RNA Kit and a QiaCube robot (Qiagen, Hilden, Germany). The RNA was quantified and the A260/280 nm and A260/230 nm ratios were determined using a NanoDrop ND1000 spectrophotometer (Wilmington, DE). RNA quality was assessed using the Bioanalyzer 2100 (Agilent, Santa Clara, CA).
Label Cy3
Label protocol cRNA was synthesized and fluorescently labelled with Cy3-CTP from 100 ng of total RNA using Agilent's Low Input Quick Amp Labeling Kit.
 
Hybridization protocol Labelled cRNA (1.65 μg) was hybridized on a Whole Human Genome 4 x 44K custom oligonucleotide microarray (G2514F, AMADID 026817; Agilent Technologies). Standard manufacturer's instructions for one-colour gene expression hybridization and washing steps were followed. The microarrays were hybridized at 65°C for 17 h in an Agilent hybridization oven with rotisserie at 10 rpm. The microarrays were washed with Agilent Wash Buffer 1, pre-warmed Wash Buffer 2 (37°C) and acetonitrile according to the manufacturer’s instructions. The last washing step was performed with Agilent Stabilization and Drying Solution for 30 sec.
Scan protocol The processed microarrays were scanned using an Agilent Microarray Scanner with a resolution of 5 μm, exploiting the extended dynamic range feature. The two images derived from each slide scanned at 10% and 100% PMT were imported into Agilent Feature Extraction software (Version 10.7.1.1) for image analysis.
Description Blood taken at 01:45 following 19.5 hours awake after following a Sleep Restriction protocol from a Per3 5\5 genotype subject (Subject AF0139)
Data processing Individual samples were filtered based on AgilentQC metrics of reproducibility statistics, minimum detection level estimates and feature flags. Samples with a median coefficient of variation of less than 10% in spike ins or non-control replicated probes (NCRPs) were retained and quantile-normalised using the R Bioconductor package limma. NCRPs along with their corresponding flags were averaged. Probes with more than 5 flagged samples within a subject in more than half of the total number of subjects were excluded. In addition, for time-series analyses, series with 2 consecutive or more than 2 missing time points were excluded.
