Sample GSM3842377 Query DataSets for GSM3842377
Status Public on Jun 01, 2020
Title OC08_ADN0162
Sample type genomic
 
Source name tumor sample
Organism Homo sapiens
Characteristics tissue: ovarian cancer biopsy
Treatment protocol none
Growth protocol DNA extract from tumor biopsies
Extracted molecule genomic DNA
Extraction protocol DNA was extracted using Macherey-Nagel NucleoSpin® Tissue kit
Label Biotin
Label protocol as per manufacturer (Affymetrix)
 
Hybridization protocol DNA was restriction digested, PCR amplified, fragmented, labeled and hybridized to each array according to the manufacturer's instructions.
Scan protocol The Arrays were then washed using Affymetrix fluidics stations, and scanned using the Gene Chip Scanner 3000.
Data processing CytoScan HD SNP-arrays (Affymetrix, ThermoFisher Scientific) data were processed using the GAP methodology to obtain absolute copy number (CN) profiles (Popova et al, Genome Biol., 2009, doi:10.1186/gb-2009-10-11-r128), including DNA structural rearrangements and chromosome number. The DNA index was calculated as the averaged CN and tumor ploidy of tumors was set as near-diploid (DNA index <1.3) or near-tetraploid (DNA index >1.3). HRD was detected based on the number of Large-scale State Transitions (LSTs) as described previously 47. Briefly, LST was defined as a chromosomal breakpoint (change in CN or major allele counts) between adjacent regions of at least 10 Mb. The number of LSTs was calculated after smoothing and filtering out CN variant regions < 3 Mb in size based on two ploidy-specific cut-offs (15 and 20 LSTs per genome in near-diploid and near-tetraploid tumors respectively). Tumors were classified as HRD (equal or above the cut-off) or HR Proficient (HRP) (below the cut-off)
