Sample GSM173121 Query DataSets for GSM173121
Status Public on Jun 01, 2007
Title g4ERbeta12h-tet+E2(5)UHR(3)array109 T47D cells with inducible ERbeta
Sample type RNA
 
Channel 1
Source name T-47D cells with inducible ERbeta construct
Organism Homo sapiens
Characteristics T-47D breast cancer cell line
Tissue: breast cancer cell line
Growth protocol Cells were added to 150 mm plates at a confluency of 40%; after one day, the normal medium was replaced by the medium described above, supplemented with 5% dextran coated charcoal treated FBS (DCCFBS). After 24h, 10 nM ICI 182,780 was added to the cultures and incubation proceeded for an additional 48h. For expression of ERb, tetracycline was removed 12 h before initiation of treatment with 17b-estradiol. At time 0 h the medium was changed to 0.5% DCCFBS and 10 nM of 17b-estradiol or equivalent volume of DMSO for mock-treated controls were added.
Extracted molecule total RNA
Extraction protocol Total RNA extracted using Trizol following manufacturer's instructions
Label Cy5
Label protocol 25 ug each of sample total RNA and human universal reference RNA (Stratagene, La Jolla, CA, USA) were labeled with Cy5-conjugated dUTP and Cy3-conjugated dUTP (PerkinElmer, Boston, MA, USA), respectively, and hybridized to the arrays using protocols established by the Patrick O. Brown Laboratory (Stanford University, USA) accessible at http://cmgm.stanford.edu/pbrown/protocols/index.html.
 
Channel 2
Source name Universal human reference RNA (Stratagene)
Organism Homo sapiens
Characteristics Purchased from Stratagene
Extracted molecule total RNA
Extraction protocol Total RNA extracted using Trizol following manufacturer's instructions
Label Cy3
Label protocol 25 ug each of sample total RNA and human universal reference RNA (Stratagene, La Jolla, CA, USA) were labeled with Cy5-conjugated dUTP and Cy3-conjugated dUTP (PerkinElmer, Boston, MA, USA), respectively, and hybridized to the arrays using protocols established by the Patrick O. Brown Laboratory (Stanford University, USA) accessible at http://cmgm.stanford.edu/pbrown/protocols/index.html.
 
 
Hybridization protocol Brown Lab protocol
Scan protocol Scanned on an Axon 4000B scanner.
Images were quantified using GenePix Pro Software.
Description induced and treated at 12 hour following E2 treatment
Data processing Signal calculation: mean intensity minus median background and normalized by median value of all spot filtered genes.
