McAb7E10 inhibits cell surface ATP generation and proliferation in AML cell. To examine the inhibitory effect of the antibody on ATP synthesis, a cell surface ATP generation assay was performed. Results showed that McAb7E10 antibody significantly inhibited ATP synthesis in AML cells. The effect of McAb7E10 on the proliferation of the AML cell lines MV4-11 and HL-60 was evaluated using the MTT assay. (A, B) ATP generation on the surface of MV4-11 (A) and HL-60 (B) cells is inhibited dose-dependently in the presence of McAb7E10 and oligomycin. Oligomycin, a known inhibitor of ATP synthase F1, was used as positive control and mouse IgG as negative control. Data represent means ± SD. (C) Proliferation analysis of MV4-11 cells treated with mouse IgG and McAb7E10. At 120 h, the relative inhibitory rates for 5, 10 and 50 μg/mL McAb7E10 treated MV4-11 cells were 24.5%, 44% and 69.6% respectively, compared to control mouse IgG treated cells. (D) Proliferation analysis of HL-60 cells treated with mouse IgG and McAb7E10. At 120 h, the relative inhibitory rates for 5, 10 and 50 μg/mL McAb7E10 treated HL-60 cells were 39.4%, 62.1% and 81.9% respectively, compared to control mouse IgG treated cells.
