Sample GSM492545 Query DataSets for GSM492545
Status Public on Apr 19, 2010
Title Integrative genomics of ovarian cancer P1680 [GenomeWideSNP_6]
Sample type genomic
 
Source name Ovarian tumours at the time of diagnosis
Organism Homo sapiens
Characteristics tissue type (t=tumour; n= normal blood lymphocyte): T&N
histological subtype: clear cell
grade: 3
stage: 2a
age: 76
scandate(batch): 4-16-08
source: Tissue_bank
Treatment protocol All tumours were fresh-frozen and OCT embedded. Lymphocytic DNA was extracted from stored blood samples.
Extracted molecule genomic DNA
Extraction protocol 10uM slices of tumour were hand-microdissected to obtain regions with >80% epithelial cells and reduce contamination from fibroblasts, blood vessels etc. Following this, for DNA extraction, slides containing sections were stained with Haematoxylin and Eosin and DNA was extracted using the Qiagen DNEasy kit. For RNA, identical slides were stained with Cresyl violet and total RNA was extracted using the Ambion mirVana kit according to manufacturer's instructions.
Label biotin
Label protocol According to Affymetrix protocol, Biotin labelled
 
Hybridization protocol According to Affymetrix protocol using recommended instrumentation
Scan protocol According to Affymetrix protocol and using GeneChip Operating Software
Description none
Data processing primary data description: Partek's copy number workflow generates copy number ratios relative to matching normal samples or a pooled baseline and then converts and presents these values as whole copy numbers. The file titled SNP6_Normalised-Copy-number.csv contains these values for each sample. In this file, probes on Chromosome Y and the Mitochondrion (MT) have been removed and the probesets are organised first by Chromosome and then by start position. Annotations for this were mapped in Partek using the Affymetrix GenomewideSNP6, CN and SNP annotation files, release number 23. This data was then used for Segmentation using the CBS algorithm in the DNAcopy package in R open-source software.
