Metastatic castration-resistant prostate cancer reveals intrapatient similarity and interpatient heterogeneity of therapeutic kinase targets.

Data from ProteomeXchange, PXD ID: PXD000238. File: Batch3_RA14LiverMetr2-35.mzml. Published as part of Proc Natl Acad Sci U S A. 2013 Nov 18 . From the Abstract: {{i}} ... We evaluated active kinases using phosphotyrosine peptide enrichment and quantitative mass spectrometry to identify druggable targets in metastatic castration-resistant prostate cancer obtained at rapid autopsy. We identified distinct phosphopeptide patterns in metastatic tissues compared with treatment-naive primary prostate tissue and prostate cancer cell line-derived xenografts ... {{/i}}
