the egfr is a mr 170,000 transmembrane glycoprotein with an external binding domain and an intracellular tyrosine kinase domain. gefitinib (zd-1839, iressa) is an epidermal growth factor receptor-selective tyrosine kinase inhibitor. | [in vitro]
gefitinib inhibited colony formation in soft agar in a dose dependent manner in all cancer cell lines. however, treatment with higher doses resulted in a 2–4-fold increases in apoptosis. dose-dependent supra-additive increase in growth inhibition was observed when cancer cells were treated with totoxic drugs and gefitinib. the combined treatment markedly enhanced apoptotic cell death induced by single agent treatment [1]. | [in vivo]
gefitinib treatment of nude mice bearing established human geo colon cancer xenografts revealed a reversible dose-dependent inhibition of tumor growth because geo tumors resumed the growth rate of controls at the end of the treatment [1]. | [target]
