Sample GSM818523 Query DataSets for GSM818523
Status Public on Sep 01, 2017
Title Heart Ctrl + corticosterone treatment sample 4 (mouse n° 261)
Sample type RNA
 
Channel 1
Source name Heart Ctrl + corticosterone treatment
Organism Mus musculus
Characteristics Sex: male
genotype: Ctrl (non-transgenic)
treatment: Corticosterone
treatment duration: 7 days
tissue: Heart
Extracted molecule total RNA
Extraction protocol Total RNA was prepared from ventricle samples with the RNeasy Mini Kit (Qiagen S.A) according to the manufacturer's instructions and its quality was assessed with Bioanalyzer 2100 (Agilent technologies)
Label Cy5
Label protocol Labelling of the RNAs weas performed according to Agilent's instruction. Briefly, 100 ng of total RNA + spikes were primed with 1,8µl of T7 promoter primer mix at 70°C for 10 min, then reversed transcribed at 40°C for 2 h in presence of a mix containing first strand buffer, 20 mM DTT, 2 mM DNTP mix and AffinityScript rnase block mix. Reaction was stopped by heating samples at 70° foc 15 min. New synthetized cDNA was then labelled and amplified at 40° for 2h in presence of a mix containing transcription buffer, NTP mix, 20mM DTT, T7 RNA polymerase and CY3-CTP or CY5-CTP.
 
Channel 2
Source name Total RNA pooled from several tissues (liver, brain, heart kidney, spleen), labeled with Cyanine-3, used as reference
Organism Mus musculus
Characteristics tissues: liver, brain, heart kidney, spleen
Extracted molecule total RNA
Extraction protocol Total RNA was prepared from ventricle samples with the RNeasy Mini Kit (Qiagen S.A) according to the manufacturer's instructions and its quality was assessed with Bioanalyzer 2100 (Agilent technologies)
Label Cy3
Label protocol Labelling of the RNAs weas performed according to Agilent's instruction. Briefly, 100 ng of total RNA + spikes were primed with 1,8µl of T7 promoter primer mix at 70°C for 10 min, then reversed transcribed at 40°C for 2 h in presence of a mix containing first strand buffer, 20 mM DTT, 2 mM DNTP mix and AffinityScript rnase block mix. Reaction was stopped by heating samples at 70° foc 15 min. New synthetized cDNA was then labelled and amplified at 40° for 2h in presence of a mix containing transcription buffer, NTP mix, 20mM DTT, T7 RNA polymerase and CY3-CTP or CY5-CTP.
 
 
Hybridization protocol 825 ng of Cy5-labelled samples and 825 ng of Cy3-labelled references were incubated at 60° for 30 min in fragmentation buffer. Hybridization buffer was then added, and sample/reference couples (1 couple per microarray) were applied to microarrays enclosed in Agilent SureHyb-enabled hybridization chambers. After hybridization, slides were washed sequential
Scan protocol Scanned on an G2505 Agilent scanner.
Images were quantified using Agilent Feature Extraction Software (version v 10.7.3.1).
Description Hearts were rinsed in cold PBS, frozen in liquid nitrogen, and kept at –80°C.
Data processing Agilent Feature Extraction Software (v 10.7.3.1) was used for background subtraction and LOWESS normalization.Data were processed using genespring software v11.0.
