Sample GSM280793 Query DataSets for GSM280793
Status Public on Jun 10, 2008
Title 22RV1 spink1 sirna rep1
Sample type RNA
 
Channel 1
Source name 22RV1-non-targeting-siRNA
Organism Homo sapiens
Characteristics 22RV1 prostate cancer cell lines transiently transfected with non targeting siRNA
Treatment protocol Cells were not treated prior to RNA extraction
Growth protocol 22RV1 cells transfected with non-targeting siRNA or siRNA targeting SPINK1 were maintained in 10% RPMI media
Extracted molecule total RNA
Extraction protocol Total RNA was isolated with Trizol (Invitrogen Cat. No. 15596-026, Carlsbad, CA), according to the manufacturer's instructions. Total RNA was further purified using the Qiagen RNAeasy Mini Kit (Cat. No. 74104) according to the manufacturer's instructions
Label Cy3
Label protocol One ug of total RNA was reverse transcripted to cDNA using T7 Promoter Primer and MMLV-RT. Then the cDNA was converted to aRNA using T7 RNA polymerase, which simultaneously amplifies target material and incorporates cyanine 3- or cyanine 5-labeled CTP (Two-Color Microarray-Based Gene Expression Analysis Protocol, Agilent).
 
Channel 2
Source name 22RV1-SPINK1-siRNA
Organism Homo sapiens
Characteristics 22RV1 prostate cancer cell lines transiently transfected with siRNA targeting SPINK1
Treatment protocol Cells were not treated prior to RNA extraction
Growth protocol 22RV1 cells transfected with non-targeting siRNA or siRNA targeting SPINK1 were maintained in 10% RPMI media
Extracted molecule total RNA
Extraction protocol Total RNA was isolated with Trizol (Invitrogen Cat. No. 15596-026, Carlsbad, CA), according to the manufacturer's instructions. Total RNA was further purified using the Qiagen RNAeasy Mini Kit (Cat. No. 74104) according to the manufacturer's instructions
Label Cy5
Label protocol One ug of total RNA was reverse transcripted to cDNA using T7 Promoter Primer and MMLV-RT. Then the cDNA was converted to aRNA using T7 RNA polymerase, which simultaneously amplifies target material and incorporates cyanine 3- or cyanine 5-labeled CTP (Two-Color Microarray-Based Gene Expression Analysis Protocol, Agilent).
 
 
Hybridization protocol 825ng of Cy3 and Cy5 labelled aRNA were hybridized competitively for 17 hrs in a 65 C hybridization oven (G2545A, Agilent) set to 10 rpm in a final concentration of 1X GEx Hybridization Buffer HI-RPM, according to the manufacturer's recommnded protocol (Two-Color Microarray-Based Gene Expression Analysis, Agilent). Arrays were washed according to the manufacturer's recommended protocol including the Stabilization and Drying Solution step (Two-Color Microarray-Based Gene Expression Analysis, Agilent).
Scan protocol Arrays were scanned at 5um resolution on an Agilent DNA Microarray Scanner (G2505B, Agilent) using the default settings for 4x44k format two-color arrays.
Description 22rv1spink1/nontarget
Data processing Images were auto gridded, analyzed and data extracted using Agilent Feature Extraction Software (Version 9.1.3.1). Spot values were normalized using the default linear-lowess normalization. Over and under-expressed signatures were generated by filtering to include only features with significant differential expression (PValueLogRatio < 0.01) in all hybridizations and Cy5/Cy3 ratios > or < 1 (non-logged) in all hybridizations after dye flip correction
