Lung adenocarcinomas induced in mice by mutant EGF receptors foundin human lung cancers respondto a tyrosine kinase inhibitor orto down-regulation of the receptors
Open accessAbstract
Somatic mutations in exons encoding the tyrosine kinase domain of the epidermal growth factor receptor ( EGFR ) gene are found in human lung adenocarcinomas and are associated with sensitivity to the tyrosine kinase inhibitors gefitinib and erlotinib. Nearly 90% of the EGFR mutations are either short, in-frame deletions in exon 19 or point mutations that result in substitution of arginine for leucine at amino acid 858 (L858R). To study further the role of these mutations in the initiation and maintenance of lung cancer, we have developed transgenic mice that express an exon 19 deletion mutant ( EGFR Δ L747–S752 ) or the L858R mutant ( EGFR L858R ) in type II pneumocytes under the control of doxycycline. Expression of either EGFR mutant leads to the development of lung adenocarcinomas. Two weeks after induction with doxycycline, mice that express the EGFR L858R allele show diffuse lung cancer highly reminiscent of human bronchioloalveolar carcinoma and later develop interspersed multifocal adenocarcinomas. In contrast, mice expressing EGFR Δ L747–S752 develop multifocal tumors embedded in normal lung parenchyma with a longer latency. With mice carrying either EGFR allele, withdrawal of doxycycline (to reduce expression of the transgene) or treatment with erlotinib (to inhibit kinase activity) causes rapid tumor regression, as assessed by magnetic resonance imaging and histopathology, demonstrating that mutant EGFR is required for tumor maintenance. These models may be useful for developing improved therapies for patients with lung cancers bearing EGFR mutations.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
