Noninvasive detection of EGFR T790M in gefitinib or erlotinib resistant non-small cell lung cancer.
PURPOSE Tumors from 50% of epidermal growth factor receptor (EGFR) mutant non-small cell lung cancer patients that develop resistance to gefitinib or erlotinib will contain a secondary EGFR T790M mutation. As most patients do not undergo repeated tumor biopsies we evaluated whether EGFR T790M could be detected using plasma DNA. EXPERIMENTAL DESIGN DNA from plasma of 54 patients with known cli...
متن کاملHsp90 inhibition by WK88-1 potently suppresses the growth of gefitinib-resistant H1975 cells harboring the T790M mutation in EGFR.
Heat shock protein 90 (Hsp90) is a molecular chaperone for numerous client proteins, many of which are crucial for the pathogenesis of non-small cell lung cancers (NSCLCs). To date, therapeutic approaches using epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) such as gefitinib or erlotinib for the treatment of NSCLCs have been limited due to the emergence of acquired drug...
متن کاملAcquired Gefitinib-Resistant Mutation of EGFR in a Chemonaive Lung Adenocarcinoma Harboring Gefitinib-Sensitive Mutation L858R
Steve Hickey, Hilary Roberts The Cochrane review by Douglas et al. [1], which is referenced in the Best Practice article by Douglas and Hemilä [2], covers 60 years of research into vitamin C and the common cold. However, the review omits pharmacokinetic data that invalidate the conclusion that vitamin C is ineffective. This conclusion is not derivable from the data presented. The dual-phase pha...
متن کاملMET amplification occurs with or without T790M mutations in EGFR mutant lung tumors with acquired resistance to gefitinib or erlotinib.
In human lung adenocarcinomas harboring EGFR mutations, a second-site point mutation that substitutes methionine for threonine at position 790 (T790M) is associated with approximately half of cases of acquired resistance to the EGFR kinase inhibitors, gefitinib and erlotinib. To identify other potential mechanisms that contribute to disease progression, we used array-based comparative genomic h...
متن کاملa frame semantic approach to the study of translating cultural scripts in salingers franny and zooey
the frame semantic theory is a nascent approach in the area of translation studies which goes beyond the linguistic barriers and helps us to incorporate cognitive and cultural factors to the study of translation. based on rojos analytical model (2002b), which centered in the frames or knowledge structures activated in the text, the present research explores the various translation problems that...
