(A) SK-N-BE(2)-c cells were treated with five doses of QW-5–70 (0.125 to 2 nM) in combination with five doses of DFMO (10–1000 μM). Cell viability was assessed using the MTS assay (n=4). (B) CI–Fa analysis of the QW-5–70 and DFMO combination. CI values were calculated using the Chou–Talalay median-effect method for five experimentally tested dose pairs at their corresponding Fa values. CI < 1, CI = 1, and CI > 1 indicate synergistic, additive, and antagonistic interactions, respectively. (C) SK-N-BE(2)-c cells were treated with five doses of QW-5–70 (0.125 to 2 nM) in combination with five doses of MLN8237 (1–100 nM). Cell viability was assessed using the MTS assay (n=4). (D) SK-N-BE(2)-C cells were treated with 1 nM QW-5–70 in combination with either DFMO (300 μM, top) or MLN8237 (30 nM, bottom) as indicated. Cell lysates were analyzed by immunoblotting for cPARP as a marker of apoptosis, with GAPDH used as a loading control. (E) Representative colony formation images of SK-N-BE(2)-C cells treated with the same combination.
