Sample GSM1103956 Query DataSets for GSM1103956
Status Public on Aug 26, 2013
Title lacZ shRNA 1
Sample type RNA
 
Source name A673 Ewing sarcoma cells
Organism Homo sapiens
Characteristics source material: EWS-FLI1-rearranged cell line
cell line: A673
treatment: lacZ shRNA
Treatment protocol For knock down experiments, A673 cells were grown to 30-35% confluence in 100 mm dishes at which point growth medium was removed and 5 ml fresh medium added along with 5 ml of virus and Polybrene at a final concentration of 8 μg/ml. After 24 hours, medium was replaced with 2 ml fresh growth medium containing puromycin at 4 μg/ml. Cells were selected for 48 hours, then harvested for Western-blot and RNA extraction.
For drug treatment experiments, A673 cells were grown to 65% confluence and then were either left untreated or treated for 24hrs with DMS0 or actinomycin D at low- (5nM) or high-dose (50nM).
Growth protocol A673 cells were obtained from American Type Culture Collection (ATCC) and cultured in DMEM with 10% FCS and RPMI-1640 20 with 15% FCS.
Extracted molecule total RNA
Extraction protocol RNA was extracted with Agilent's Absolutely RNA kit.
Label biotin
Label protocol 100 ng of total RNA was submitted to the DFCI Microarray Core Facility for biotin labelling and hybridization to Affymetrix HuGene 1.0 ST Arrays.
 
Hybridization protocol Standard Affymetrix protocol.
Scan protocol Standard Affymetrix protocol.
Description lacZ-48 hrs-1
Data processing Array quality was verified before background correction, RMA normalization and log2 conversion using the Bioconductor R package affy (URL: http://www.bioconductor.org).
