Proteomic Dynamics of Breast Cancer Cell Lines Identifies Potential Therapeutic Protein Targets

ABSTRACT: Treatment and relevant targets for breast cancer (BC) remain limited, especially for triple-negative BC (TNBC). We identified 6091 proteins of 76 human BC cell lines using data-independent acquisition (DIA). Integrating prior multi-omics datasets with our proteomic results, we found that including proteomics data improved drug sensitivity predictions and provided insights into mechanism of action. We then profiled the proteome changes in nine cell lines (five TNBC, four non-TNBC) treated with EGFR/AKT/mTOR inhibitors. In TNBC, metabolism pathways were dysregulated after EGFR/mTOR inhibitor treatment, while RNA modification and cell cycle pathways were affected by AKT inhibitor. This systematic multi-omics and in-depth analysis of the proteome of BC cells can help prioritize potential therapeutic targets and provides insights into adaptive resistance in TNBC.
