タイトル Sensitivity of SNX2-ABL1 toward tyrosine kinase inhibitors distinct from that of BCR-ABL1.
ジャーナル Leuk Res
Abstract We introduced SNX2-ABL1, a novel ABL1-related chimeric transcript lacks SH3 and SH2 domains, into murine Ba/F3 cells and compared their function with that of BCR-ABL1. After the expression of SNX2-ABL1 proteins, Ba/F3 cells acquired an ability to proliferate in an IL-3-independent manner. Upon treatment with both imatinib and dasatinib, BCR-ABL1-expressing Ba/F3 cells underwent rapid apoptosis, whereas SNX2-ABL1-expressing Ba/F3 cells showed poorer sensitivity toward these TKIs and could proliferate in the presence of a low dose of dasatinib. Therefore, other TKIs with a more selective effect against this chimeric kinase should be used for the treatment of patients with SNX2-ABL1+ ALL.
