Analysis of genomic DNA of 126 lung adenocarcinoma patients for the Met juxtamembrane domain revealed the same Arg/Cys variation at the mouse homologous position in one patient; two other patients carried additional variants in the same domain, suggesting a potential role for rare MET juxtamembrane variants in human lung cancer.
CL-387,785 sensitivity and signal transduction in H1975 cells were examined in the presence or absence of HGF or HGF-producing fibroblasts with or without HGF-MET inhibitors.
Clinical resistance to epidermal growth factor receptor (EGFR) inhibition in lung cancer has been linked to the emergence of the EGFR T790M resistance mutation or amplification of MET.
Clinical resistance to gefitinib, an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), in patients with lung cancer has been linked to acquisition of the T790M resistance mutation in activated EGFR or amplification of MET.
Correlation between MET protein expression and MET gene copy number in a Caucasian cohort of non-small cell lung cancers according to the new IASLC/ATS/ERS classification.
Crizotinib shows a marked antitumor action in MET amplification-positive lung cancer cells but not in cells without MET amplification, including those with a MET mutation.
Data were reviewed for patients with advanced lung adenocarcinomas enrolled in the Lung Cancer Mutation Consortium whose tumors underwent testing for mutations in epidermal growth factor receptor (EGFR), Kirsten rat sarcoma viral oncogene homolog (KRAS), human epidermal growth factor receptor 2 (HER2), AKT1, BRAF, dual-specificity mitogen-activated protein kinase kinase 1 (MEK1), neuroblastoma RAS viral (v-ras) oncogene homolog (NRAS), and phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit α (PIK3CA); for anaplastic lymphoma kinase (ALK) translocations; and for MET amplification.
Evidence that depletion of the sorting nexin 1 by siRNA promotes HGF-induced MET endocytosis and MET phosphorylation in a gefitinib-resistant human lung cancer cell line.
Exogenous miR-1 significantly reduced expression of oncogenic targets, such as MET, a receptor tyrosine kinase, and Pim-1, a Ser/Thr kinase, frequently up-regulated in lung cancer.
