Sample GSM750737 Query DataSets for GSM750737
Status Public on Jun 29, 2011
Title breast cancer FA09
Sample type RNA
 
Source name breast cancer FNA biopsy, pre-treatment
Organism Homo sapiens
Characteristics tissue: breast cancer FNA biopsy
pcr.v.rd: NA
array.qc: Pass
p53 status: n/a
er positive vs negative by esr1 mrna gene expression (probe: 205225_at): ERneg
er positive vs negative by immunohistochemistry: NA
age: NA
prechemo t: NA
postchemo tumor size: NA
prechemo n: NA
bmn.grade: NA
Treatment protocol Patients received neoadjuvant chemotherapy regimen with 5-Fluorouracil, Doxorubicin (Epirubicin) and Cyclophosphamide
Growth protocol N/A
Extracted molecule total RNA
Extraction protocol total RNA was extracted from the FNA specimens using Qiagen RNeasy kit following the manufacturer’s instructions (http://www.qiagen.com).
Label biotin
Label protocol Biotinylated cRNA were prepared according to the standard Affymetrix protocol from at least 1 ug total RNA using the BioArray High Yield RNA transcript labeling kit (Enzo Laboratories).
 
Hybridization protocol Following fragmentation, 20 ug of cRNA were hybridized to affymetrix U133A arrays overnight at 42C. Microarrays were washed and stained in the Affymetrix Fluidics Station.
Scan protocol GeneChips were scanned using the Affymetrix GeneChip Scanner 3000DX. This system is manufactured by Affymetrix Inc in Santa Clara, CA.
Description Gene expression data from breast cancer FNA biopsy, pre-treatment
Characteristics legend:
pCR: pathologic complete response was defined as no residual invasive cancer in the breast and lymph nodes after preoperative chemotherapy.
RD: residual disease was defined as any degree of invasive cancer that survived preoperative chemotherapy.
Prechemo T and Prechemo N: were modified by TNM staging system in the American Joint Committee on Cancer
Prechemo Tumor size: Clinical tumor size
BMN.grade: were modified by Black's Nuclear Grade
Data processing The data were normalized using dChip version 1.3 followed by logrithm-base-2 sc600 transformation. The dChip version 1.3 was used to calculate Model Based Expression Index (MBEI) values of the arrays using the digital standard microarray MDA-BCNorm.CEL and the probe sensitivity index file UTMDACC-BreastCancerNormalizer.psi as described in Hess, et. al, Pharmacogenomic Predictor of Sensitivity to Preoperative Chemotherapy With Paclitaxel and 5-Fluorouracil, Doxorubicin, and Cyclophosphamide in Breast Cancer, Journal of Clinical Oncology, 24 (26), 2006.
