Transcription profiling of mouse EGFR mutants


ABSTRACT: We performed mRNA expression profiling of lung tumors from C/L858R, C/T790M, and C/L+T mice and from corresponding normal lung tissue. Experiment Overall Design: mRNA was extracted from pulverized lung samples using Trizol (Invitrogen) and then hybridized to MOE 430 2.0 chips (Affymetrix) using standard hybridization techniques.

ORGANISM(S): Mus musculus

EGFR is a major anticancer drug target in human epithelial tumors. One effective class of agents is the tyrosine kinase inhibitors (TKIs), such as gefitinib and erlotinib. These drugs induce dramatic responses in individuals with lung adenocarcinomas characterized by mutations in exons encoding the EGFR tyrosine kinase domain, but disease progression invariably occurs. A major reason for such acquired resistance is the outgrowth of tumor cells with additional TKI-resistant EGFR mutations. Here w  ...[more]
