Sample GSM1380095 Query DataSets for GSM1380095
Status Public on Jan 01, 2015
Title P00317 Idiopathic Dilated CMP Left Ventricle
Sample type RNA
 
Source name heart left ventricle, idiopathic dilated CMP
Organism Homo sapiens
Characteristics tissue: heart left ventricle
heart failure: yes
disease status: idiopathic dilated CMP
gender: female
age: 60
Treatment protocol Explanted myocardium snap frozen in liquid nitrogen.
Growth protocol None
Extracted molecule total RNA
Extraction protocol Trizol extraction of total RNA was performed according to the manufacturer's instructions.
Label biotin
Label protocol 100ng of total RNA was converted to first-strand cDNA using reverse transcriptase primed by a poly(T) oligomer that incorporated the T7 RNA polymerase promoter. Second-strand cDNA synthesis was followed by in vitro transcription (Affymetrix One-Cycle Target Labeling Kit) for linear amplification and biotinylation of each transcript.
 
Hybridization protocol cDNAs were added to Affymetrix hybridization cocktails, heated at 99ºC for 2 min and hybridized for 16 h at 45ºC to Affymetrix Human Gene 1.1 ST Array GeneChips (Affymetrix Inc., Santa Clara, CA). The microarrays were then washed at low (6X SSPE) and high (100mM MES, 0.1M NaCl) stringency and stained with streptavidin-phycoerythrin. Fluorescence was amplified by adding biotinylated anti-streptavidin and an additional aliquot of streptavidin-phycoerythrin stain.
Scan protocol A confocal scanner was used to collect fluorescence signal after excitation at 570 nm.
Description P00317
PolyA mRNA
Data processing Microarray data were analyzed using the Oligo package available at the Bioconductor website (www.bioconductor.org). The raw data were first background-corrected by the Robust Multichip Average (RMA) method and then normalized by an invariant set method. Microarray Processing batch were controlled for using the R package Combat. Differential gene expression was analyzed by the Limma package available at the Bioconductor website. P-values obtained from the multiple comparison tests were corrected by false discovery rates.
