Overcoming resistance to tyrosine kinase inhibitors: Lessons learned from cancer cells treated with EGFR antagonists
1 Jan 2009
Abstract excerpt
Tyrosine kinase inhibitors (TKIs) are effective anti-cancer therapies but resistance to these agents eventually develops. Several models of resistance to TKIs have been studied including resistance to EGFR inhibitors. Recent studies in EGFR-dependent A431 cells found upregulation of the IGF1R pathway as a mechanism to overcome blockade of EGFR. This was associated with amplification of IGF1R signaling and...
