Sample GSM1070625 Query DataSets for GSM1070625
Status Public on Jan 30, 2013
Title MCF-7aro (AD) replicate 2
Sample type RNA
 
Source name cell population of MCF-7 stably transfected with the human placental aromatase gene sensitive to letrozole (MCF-7aro cells)
Organism Homo sapiens
Characteristics cell line: MCF-7
Treatment protocol Prior to experiment, cells were purged in Dulbecco’s Modified Eagle Medium without phenol red, supplemented with 3% steroid-depleted, dextran-coated and charcoal-treated fetal calf serum (DCC medium) for 4 days. MCF-7aro and Res-Let cells were then grown for 4 days in the presence of 25 nM of androstenedione combined or not with 10-6 M of letrozole. Media and treatment were changed every 2 days.
Growth protocol Cells were grown in DMEM medium supplemented with 10% fetal bovine serum
Extracted molecule total RNA
Extraction protocol Total RNA from cell culture was prepared using the miRNeasy Mini Kit (Qiagen, Hilden, Germany) according to the manufacturer’s recommendations and subsequently quantified on a Nanodrop ND1000 spectrophotometer (Nanodrop Technologies, Wilmington, DE, USA). RNA integrity was checked using the BioAnalyzer 2100 (Agilent Technologies, Palo Alto, CA, USA).
Label biotin
Label protocol Complex probes were produced from total RNA using the FlashTag™ Biotin HSR RNA labeling kit (Affymetrix, Santa Clara, CA, USA)
 
Hybridization protocol Complex probes were hybridized to each GeneChip® miRNA 3.0 array according to the manufacturer's recommendations (Affymetrix).
Scan protocol GeneChips were scanned using the GeneChip Scanner 3000.
Description miRNA expression data from cell population of MCF-7aro treated in the presence of 25 nM of androstenedione, cell culture replicate 2
Data processing Scanned images of microarray chips were analyzed using Expression Console (Affymetrix) with the default settings. Raw data were processed using different algorithms. Detected Above Background algorithm (DABD) and RMA Background Adjustment algorithm were performed in order to remove the background value.
