Effect of methotrexate, 6-mercaptopurine and 5-fluorouracil alone on ATP levels (A, B & C) and caspase 3 activity (D, E & F) in two lymphoid (CCRF-CEM and Jurkat), two myeloid (THP-1 and KG-1a) leukemia cell lines, and two non-tumor control cells (CD133+ HSC and CD34+ HSC). The lowest significant doses (LSD): which caused a significant reduction on ATP levels and induction of caspase 3 activity when compared to the vehicle control were determined for each anti-metabolite agent in each cell lines. The * indicated for LSD in each cell line.
