Mig6 and therapeutic efficacy
We identify markers capable of guiding the decision to incorporate epidermal growth factor receptor (EGFR) inhibitors, in particular EGFR tyrosine kinase inhibitors (TKIs), into chemotherapeutic regimens. Mitogen-inducible gene 6 (Mig6), a negative regulator of EGFR, is selectively upregulated during the development of resistance to the EGFR tyrosine kinase inhibitor (TKI) erlotinib, resulting in decreased EGFR phosphorylation. The ratio of Mig6 / EGFR expression highly correlates with erlotinib sensitivity. A low Mig6 / EGFR ratio correlates with a high response rate to gefitinib and a marked increase in progression-free survival for patients. The ratio of Mig6 to EGFR is a major predictor of biologic and clinical responses to EGFR inhibitors.
