Abstract | BACKGROUND/AIM: MATERIALS AND METHODS: RESULTS: Despite 20-fold cytarabine resistance, the HL/ara-C20 cells exhibited only a 6-fold resistance to clofarabine compared to HL-60 cells. The intracellular concentration of the triphosphate metabolite of cytarabine was reduced to 1/10, and that of clofarabine was halved in the HL/ara-C20 cells. hENT1 and dCK were reduced, but hCNT3 and dGK were not altered in the HL/ara-C20 cells, which might contribute to their retained capability to produce intracellular triphosphate metabolite of clofarabine. CONCLUSION:
