Sample GSM969465 Query DataSets for GSM969465
Status Public on Nov 30, 2012
Title LNCaP siEZH2 at DHT rep 0
Sample type RNA
 
Source name LNCaP cells depleted of EZH2 in the presence of 10 nM DHT
Organism Homo sapiens
Characteristics cell line: LNCaP prostate cancer cells
genotype/variation: depleted of EZH2
treatment protocol: in the presence of DHT
Treatment protocol Cells were transfected with either control siRNA (siCtrl) or siRNAs targeting EZH2 (siEZH2), and maintained in androgen-depleted medium for 24 hours, and then treated with either 10 nM 5α-dihydrotestosterone (DHT, for LNCaP cells) or with ethanol only (for abl cells) for another 24 hours before the RNA was extracted.
Growth protocol LNCaP cells were routinely maintained in RPMI-1640 with 10% fetal bovine serum (FBS) plus 1% antibiotics (penicillin and streptomycin). LNCaP-abl (abl) cells were routinely maintained in phenol-red-free RPMI with 10% charcoal-stripped FBS plus 1% antibiotics.
Extracted molecule total RNA
Extraction protocol Trizol extraction of total RNA was performed according to the manufacturer's instructions, followed by additional purification using RNeasy Kit (Qiagen, Cat#74104).
Label biotin
Label protocol Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 8-15 ug total RNA (Expression Analysis Technical Manual, 2001, Affymetrix).
 
Hybridization protocol Following fragmentation, 15 ug of cRNA were hybridized overnight at 45ºC on Affymetrix human U133 plus 2.0 expression array. The chips were transferred to a fluidics instrument that performs washes and then fluorescently labeled using phycoerythrin-conjugated streptavidin (SAPE).
Scan protocol GeneChips were scanned using the GeneChip Scanner 3000 7G.
Description Gene expression data from LNCaP cells after transfection with siRNA against EZH2
LNCaP-DHT-siEZH2-0
Data processing The data is processed by RMA with quantile normalization.
Probes are converted to genes by averaging values of probes mapped to the same gene. Combat is used to remove the batch effect. The Combat-Matrix.txt files are linked as supplementary files on the Series record.
