Sample GSM462981 Query DataSets for GSM462981
Status Public on May 21, 2010
Title - RA - RA.time
Sample type RNA
 
Channel 1
Source name MCF7_48hr_UT_8
Organism Homo sapiens
Characteristics cell line: MCF-7
time: 48 hours
protocol: untreated
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 RNA was extracted with miRNeasy minikit (Qiagen).
Label Cy5
Label protocol miRNA was labeled by RNA-ligase mediated ligation of Cy dye-coupled dinucleotides.

protocol: RA treated
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 RNA was extracted with miRNeasy minikit (Qiagen).
Label Cy3
Label protocol miRNA was labeled by RNA-ligase mediated ligation of Cy dye-coupled dinucleotides.
 
 
Hybridization protocol hybridysed at Adelaide Microarray Facility http://www.microarray.adelaide.edu.au/
Scan protocol Slides were scanned with a GenePix 4000B Scanner (Axon Instruments)
Description no additional information
Data processing Image analysis and spot identification and intensity extraction was performed using the Spot software package (http://experimental.act.cmis.csiro.au/Spot/index.php, CSIRO, Australia). Spot uses a seeded region growing algorithm to identify spots and is able to identify non-uniform shaped spots. Morphological opening background correction was applied to mean spot signal intensities. Analysis was performed in R with LIMMA package of BioConductor. Intensity-dependent global loess normalization was applied and the linear model fitted.
VALUE = normalized log2 ratio (Cy5/Cy3)
