CPTAC, TCGA Cancer Proteome Study of Ovarian Tissue

Explore This Study at the NCI Proteomic Data Commons

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.
