Combined proteomics and transcriptomics identifies carboxypeptidase B1 and NF-kappa-B associated proteins as putative biomarkers of metastasis in low grade breast cancer

Data from ProteomeXchange, PXD ID: PXD000029. File: IDRIMA_top10HCD_60min_E1_ALL.mgf. From ProteomeXchange: {{i}} Current prognostic factors are insufficient for precise risk-discrimination in breast cancer patients with low grade breast tumors, which, in disagreement with theoretical prognosis, occasionally form early lymph node metastasis. To identify markers for this group of patients, we employed iTRAQ-2DLC-MS/MS proteomics to 24 lymph node positive and 24 lymph node negative grade 1 luminal A primary breast tumors. Another group of 48 high-grade tumors (luminal B, triple negative, Her-2 subtypes) was also analyzed to investigate marker specificity for grade 1 luminal A tumors ... {{/i}}
