EGFR G796D mutation mediates resistance to osimertinib
Osimertinib is an effective third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) approved in multiple countries and regions for patients with EGFR T790M mutation-positive non-small cell lung cancer (NSCLC). Despite impressive initial tumor responses, development of drug resistance ultimately limits the benefit of this compound. Mechanisms of resistance to osi...
متن کاملHeterogeneity‐based, multiple mechanisms in the resistance to osimertinib (AZD9291): A case report
Osimertinib is a novel, irreversible, mutant-selective epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor targeting EGFR mutations and the EGFR T790 mutation. Here, we report a woman with EGFR-mutated lung adenocarcinoma who, after 23-month treatment with gefitinib, developed the EGFR T790M mutation, which converted the T790M status from positive to negative before osimertinib tr...
متن کاملresistance mechanisms of anopheles stephensi (diptera: culicidae) to temephos
background : anopheles stephensi is a sub-tropical species and has been considered as one of the most important vector of human malaria throughout the middle east and south asian region including the malarious areas of southern iran. current reports confirmed an. stephensi resistance to temephos in oman and india. however, there is no comprehensive research on mechanisms of temephos resistance ...
متن کاملMechanisms of resistance to cabazitaxel.
We studied mechanisms of resistance to the novel taxane cabazitaxel in established cellular models of taxane resistance. We also developed cabazitaxel-resistant variants from MCF-7 breast cancer cells by stepwise selection in drug alone (MCF-7/CTAX) or drug plus the transport inhibitor PSC-833 (MCF-7/CTAX-P). Among multidrug-resistant (MDR) variants, cabazitaxel was relatively less cross-resist...
متن کاملMechanisms of resistance to camptothecins.
Camptothecins are broad-spectrum anticancer drugs that specifically target DNA topoisomerase I. Although the availability of camptothecins has had a significant impact on cancer therapeutics, de novo or acquired clinical resistance to camptothecins is common. Studies of camptothecin resistance using yeast and mammalian cell culture models suggest three general mechanisms of resistance: (1) redu...
