摘要: Abstract ABCB1/P-glycoprotein (Pgp) and ABCG2/BCRP overexpression have been described as related to imatinib resistance in chronic myeloid leukemia (CML). We showed CML cells from 55 patients that Pgp activity was more frequently detected than BCRP (p = 0.0074). Imatinib-induced Crkl phosphorylated protein (pCrkl) reduction pronounced K562 (Pgp-negative) K562-Lucena (Pgp-positive) cell line. Expressive pCrkl levels after vitro treatment observed samples exhibiting lower compared with higher (p = 0.0045). association might help distinguish between imatinib-resistant imatinib-sensitive cells.
