Cell growth inhibition by dasatinib and cellular signaling in a nilotinib resistant cell line. (A) K562NR cells exposed to dasatinib or nilotinib for 72-hrs were quantitated by cell proliferation. Each result is presented as the mean percentage of proliferation of unexposed control cultures. (B) Phosphorylation of Lyn, Src, cleaved caspase 3, PARP, p21, cyclin D1, and actin levels were analyzed by immunoblotting using the protein (30 μg) from cell lysates.
