Sample GSM3151700 Query DataSets for GSM3151700
Status Public on May 25, 2018
Title Sample14: Umbilical cord blood - Depression
Sample type RNA
 
Source name Umbilical cord blood
Organism Homo sapiens
Characteristics tissue: Umbilical cord blood
maternal diagnosis: Depression
neonate gender: Female
rin: 8.3
microarray batch: One
Treatment protocol Umbilical cord blood was collected by trained staff after offspring delivery but before delivery of the placenta. The cord was clamped and cut, after which the clamp was released and cord blood drained by gravity into a kidney collection dish. Cord blood was collected using a syringe for processing and storage at -80C in PAXgene RNA tubes.
Extracted molecule total RNA
Extraction protocol RNA was extracted from PAXgene RNA tubes as per the manufacturer's instructions. All samples had a Bioanalyzer RNA Integrity Number (RIN) >7.
Label biotin
Label protocol Complementary DNA was derived from RNA and then hybridized, and raw probe intensities were generated on Illumina HumanHT-12 v4 BeadChip arrays.
 
Hybridization protocol Standard Illumina hybridization protocol
Scan protocol Standard Illumina scanning protocol
Description rep1
Data processing All statistical analyses were conducted in the statistical package R. All gene expression data were processed, normalized and quality treated. Raw data were background corrected, quantile normalized and log2 ransformed using the neqc function of limma, a robust method for Illumina BeadChips. Non-specific filtering retained probes expressed in at least 50 arrays with a detection P-value <0.05. When multiple microarray probes mapped to the same HGNC symbol, we used a median reduction technique and used the resulting collapsed expression profile for each gene for further analysis. Resulting normalized data were inspected for outlying samples using unsupervised hierarchical clustering of samples and principal component analysis to identify potential outliers outside two standard deviations from these grand averages. Based on these metrics, 19 samples were labeled as outliers and 149 samples passed into the subsequent analyses.
