SILAC proteomics analysis to discover effect sensors of EGFR inhibition


ABSTRACT: Targeted therapies against EGFR show clinical benefit, but resistance to these agents invariably develops. Thus, there is a need for dynamic biomarkers - effect sensors - that reflect treatment with EGFR therapeutics during therapy. Making use of SILAC-labeling we aimed to discover plasma membrane proteins that become differentially expressed after treatment with EGFR inhibitor erlotinib in three erlotinib-sensitive breast cancer cell lines.

Tumor responses to cancer therapeutics are generally monitored every 2-3 months based on changes in tumor size. Dynamic biomarkers that reflect effective engagement of targeted therapeutics to the targeted pathway, so-called "effect sensors", would fulfill a need for non-invasive, drug-specific indicators of early treatment effect. Using a proteomics approach to identify effect sensors, we demonstrated MUC1 upregulation in response to epidermal growth factor receptor (EGFR)-targeting treatments  ...[more]
