- Description
- In an in vitro study, stochastic mutations in the ABL1 region of a stably expressed p210 BCR-ABL fusion were generated in Ba/F3 cell lines from five independently derived, mutagenized libraries. Dasatinib resistant subclones were identified using 50 nM dasatinib in liquid culture. 201 individual clones were identified representing 10 different mutations at 6 different residues. 10 of these clones had F317L mutations. To validate resistance to dasatinib, a Ba/F3 cell line stably expressing the F317L mutation in the ABL1 region of the BCR-ABL fusion was generated and associated with higher dasatinib IC50 of 18 nM vs 1.34 nM in wildtype as determined by dose response curves.
