Sample GSM1196243 Query DataSets for GSM1196243
Status Public on Feb 01, 2016
Title 244939_1_Ctx
Sample type RNA
 
Channel 1
Source name tumor
Organism Mus musculus
Characteristics tissue: high-grade astrocytoma (HGA) tumor
ID: 244939
genotype: TRPhet
brain location: Ctx
batch: 2
subtype: 3
survival (mo): 3.94
diagnosis: A3
Treatment protocol Tumors were harvested from bains of mice and immediately flash-frozen in liquid nitrogen.
Extracted molecule total RNA
Extraction protocol Total RNA was extracted s with Qiagen RNeasy kit according to manufacturer's instructions
Label Cy5
Label protocol Labeling was performed according to the Low RNA Input Linear Amplification kit from Agilent. 1µg of RNA was primed with 1.2 µl of provided T7 promoter primer at 65 °C for 10 minutes. Reverse transcription was performed with provided Moloney Murine Leukemia Virus Reverse Transcriptase at 40 °C for 2 hours, 65 °C for 15 minutes, and 4 °C for 5 minutes. Laeled RNA was made by adding 1µl of 10mM Cy3 or Cy5 added to trancription cocktail and incubated at 40 °C for 2 hours, 4 °C for 1 minute.
 
Channel 2
Source name Stratagene whole mouse reference RNA
Organism Mus musculus
Characteristics sample type: Stratagene whole mouse reference RNA
Treatment protocol Tumors were harvested from bains of mice and immediately flash-frozen in liquid nitrogen.
Extracted molecule total RNA
Extraction protocol Total RNA was extracted s with Qiagen RNeasy kit according to manufacturer's instructions
Label Cy3
Label protocol Labeling was performed according to the Low RNA Input Linear Amplification kit from Agilent. 1µg of RNA was primed with 1.2 µl of provided T7 promoter primer at 65 °C for 10 minutes. Reverse transcription was performed with provided Moloney Murine Leukemia Virus Reverse Transcriptase at 40 °C for 2 hours, 65 °C for 15 minutes, and 4 °C for 5 minutes. Laeled RNA was made by adding 1µl of 10mM Cy3 or Cy5 added to trancription cocktail and incubated at 40 °C for 2 hours, 4 °C for 1 minute.
 
 
Hybridization protocol Labeled sample RNA and Stratagen Universal Mouse Reference RNA (Agilent, #740100) as a reference were cohybridized at 65 C for 17 hours in a rotating hybridization oven.
Scan protocol Microarrays were scanned on an Agilent Technologies DNA Microarray Scanner with Surescan High-Resolution Technology (Part no. G2565CA)
Data processing Image analyzed using Agilent Feature Extraction Software. Data was uploaded to the UNC microarray database (UMD). Data was normalized in UMD using Lowess normalization on the Cy3 and Cy5 channels. Data extraction was performed by selecting genes with an absolute signal intensity of at least 10 units in both dye channels and data present in at least 70% of experimental samples, afterwhich replicate probe IDs were collapsed by averaging. Samples from different batches were combined using the parametric settings in combatR, a module in the R statistical programming language (R Development Core Team, 2006 http://www.R-project.org) with no covariates included. Normalized data provided is the filtered, batch combined, non-median centered data used to draw conclusions in the study.
