Sample GSM458615 Query DataSets for GSM458615
Status Public on May 21, 2010
Title MDA-MB-231 cells, retinoic acid effect, time 48h, repl2
Sample type RNA
 
Channel 1
Source name MDA-MB-231 cells, retinoic acid treated, time 48h, repl2
Organism Homo sapiens
Characteristics cell line: MDA-MB-231
treatment: 1 microM Retinoic Acid
time: 48 hours
Treatment protocol logarithmically growing cells were cultured in the presence or absence of 1 micromolar all-trans retinoic acid for 6 or 48 hours. At the end of the experiment total RNA, containing the microRNA fraction, was extracted and used for miR and GX profiling
Growth protocol Cells were grown in F12 medium containing 5% charcoal stripped fetal bovine serum (lonza) containing 10 nM beta-estradiol
Extracted molecule total RNA
Extraction protocol total RNA extracted using Qiagen miRNeasy kit, followed by Rneasy MinElute Cleanup, following manufacturer's instructions
Label Cy5
Label protocol Amino Allyl cDNA Labeling Kit (cat 1705, Ambion), following manufacturer's instructions. Samples were then diluted 1:10 and 15 picomoles of each dye were used for hyhbridization
 
Channel 2
Source name MDA-MB-231 cells, untreated, time 48h, repl2
Organism Homo sapiens
Characteristics cell line: MDA-MB-231
treatment: Vehicle
time: 48 hours
Treatment protocol logarithmically growing cells were cultured in the presence or absence of 1 micromolar all-trans retinoic acid for 6 or 48 hours. At the end of the experiment total RNA, containing the microRNA fraction, was extracted and used for miR and GX profiling
Growth protocol Cells were grown in F12 medium containing 5% charcoal stripped fetal bovine serum (lonza) containing 10 nM beta-estradiol
Extracted molecule total RNA
Extraction protocol total RNA extracted using Qiagen miRNeasy kit, followed by Rneasy MinElute Cleanup, following manufacturer's instructions
Label Cy3
Label protocol Amino Allyl cDNA Labeling Kit (cat 1705, Ambion), following manufacturer's instructions. Samples were then diluted 1:10 and 15 picomoles of each dye were used for hyhbridization
 
 
Hybridization protocol hybridization and washing were done according to Agilent protocol (GE version 5.5 )
Scan protocol Agilent Technologies Scanner G2505B US45102933, 5 micron resolution and XDR protocol, using the Agilent scan control software.
Description Biological replicates 2 of 2
Data processing Image data analysis was performed using the Feature extraction software (v9.1). The raw data FE files report log10 (Cy5/Cy3) ratios. Detailed description of the protocols used is reported in each raw data file. LogRatios are derived by Lowess normalizatin of Median Signals (maNorm function of marray package in Bioconductor).
