Proteome-Centric Cross-Omics Characterization and Integrated Network Analyses of Triple-Negative Breast Cancer

ABSTRACT: We undertook the first systemic proteomic study of a 90-case cohort of triple-negative breast cancer (TNBC) with a panoramic proteome view in quantification, phosphorylation, and DNA-binding capacity. Four integrative subtypes (iP-1-4) were stratified based on the proteome quantification profile and phosphoproteome, each of which exhibited distinct molecular, pathway, and network characteristics. Integrated network analyses of 3 proteomic datasets, together with those of genome and transcriptome from the same cohort, revealed holistic views of altered cellular processes and their regulation by/of upstream/downstream molecules, pathways and functional communities in the background of an integrated molecular network.

We report a comprehensive proteomic study of a 90-case cohort of paired samples of triple-negative breast cancer (TNBC) in quantification, phosphorylation, and DNA-binding capacity. Four integrative subtypes (iP-1-4) are stratified on the basis of global proteome and phosphoproteome, each of which exhibits distinct molecular and pathway features. Scaffold and co-expression network analyses of three proteomic datasets, integrated with those from genome and transcriptome of the same cohort, reveal  ...[more]
