Sample GSM2279234 Query DataSets for GSM2279234
Status Public on Mar 26, 2018
Title HumanOmni2.5 NPF2
Sample type genomic
Source name NPF
Organism Homo sapiens
Characteristics patient: 2
gender: Male
tissue: Prostate
cell type: Normal Prostate Fibroblast
Treatment protocol Cells were cultured in standard media to approximately 80% confluency before being trypsinised, resuspended in media and then centrifuged to create cell pellets. Cells were stored at -80°C until DNA extraction.
Growth protocol Prostate tissue was chopped into small pieces, approximately 2 mm3, and digested overnight at 37°C in RPMI containing 10% fetal calf serum (FCS), 25 mM HEPES, 100 U/mL penicillin, 100 mg/mL streptomycin, 0.5 mg/mL fungizone, 100 mg/mL gentamicin, 225 U/mL Collagenase Type I and 125 U/mL Hyaluronidase Type II (Sigma Aldrich) as previously described [PMID: 23558784]. Cell suspensions were seeded in RPMI containing 5% FCS, penicillin/streptomycin, 1 nM testosterone (Sigma Aldrich) and 10 ng/mL bFGF (Millipore), a medium that selects for fibroblasts compared to other prostatic cell types. Cells were grown at 37°C in a humidified incubator with 5% O2 and 5% CO2. The first passage of cells typically reached confluency within 2 weeks. The cells were used between passages 2-6.
Extracted molecule genomic DNA
Extraction protocol DNA was extracted from CAF and NPF samples using the DNeasy kit (Qiagen) with on-column RNase A digestion. Eluates were precipitated with 0.1 volume sodium acetate and 2.5 volumes ethanol and then resuspended in nuclease-free water. DNA was quantified using a NanoDrop 2000. 200ng of DNA was quantified using the Illumina HumanOmni2.5-8 Beadchip (Illumina, CA, USA)

Description NPF2
Data processing Copy numbers were estimated using circular binary segmentation (CBS) [PMID: 15475419] to translate intensity measurements into regions of equal copy number. The raw array data was processed using crlmm (v1.25.1) [PMID: 19661241] for background correction and normalization, accounting for batch effects.The resulting log R ratios were then smoothed to remove outliers prior to segmentation (R package DNAcopy). All analyses were carried out in R3.1.2 (
