Description
In an in vitro study of imatinib sensitivity, KIT W557_K558del was cloned into a plasmid by site-directed mutagenesis of KIT WT cDNA. Chinese hamster ovary cells were transiently transfected with the plasmid. Cells were treated with control media or media containing various concentrations of imatinib for 90 minutes. Protein lysates from the transfected cells were examined for phosphorylated tyrosine, a measure of KIT activation. Cells expressing KIT W557_K558del were as sensitive to imatinib as ligand activated wildtype KIT (IC50: 100-200 nmol/L).
