CPTAC, TCGA Cancer Proteome Study of Ovarian Tissue


Global proteome data have been acquired for 174 TCGA ovarian cancer tumor samples by 2 Proteome Characterization Centers (PCCs), Pacific Northwest National Laboratory (PNNL) and Johns Hopkins University (JHU). Both PCCs used iTRAQ (isobaric Tags for Relative and Absolute Quantification) protein quantification methods. Thirty-two of the 174 TCGA tumor samples were assayed at both sites yielding a total of 206 proteome characterizations. Glycoproteome (122 tumors) and phosphoproteome (69 tumors) analyses were also conducted, at JHU and PNNL respectively.

Information on the complete TCGA Ovarian Serous Cystadenocarcinoma (OV) cohort can be found here.
The Cancer Genome Atlas Research Network published on the Genomic characterization of the OV cohort in Nature on June 30, 2011
