PG - 301-8 LID - 10.1111/j.1742-4658.2009.07448.x [doi] AB - Epidermal growth factor receptor (EGFR) and its three related proteins (the ERBB family) are receptor tyrosine kinases that play essential roles in both normal physiological conditions and cancerous conditions. Upon binding its ligands, dynamic conformational changes occur in both extracellular and intracellular domains of the receptor tyrosine kinases, resulting in the transphosphorylation of tyrosine residues in the C-terminal regulatory domain. These provide docking sites for downstream molecules and lead to the evasion of apoptosis, to proliferation, to invasion and to metastases, all of which are important for the cancer phenotype. Mutation in the tyrosine kinase domain of the EGFR gene was found in a subset of lung cancers in 2002. Lung cancers with an EGFR mutation are highly sensitive to EGFR tyrosine kinase inhibitors, such as gefitinib and erlotinib. Here, we review the discovery of EGFR, the EGFR signal transduction pathway and mutations of the EGFR gene in lung cancers and glioblastomas. The biological significance of such mutations and their relationship with other activated genes in lung cancers are also discussed.
