Fig 5. Sensitivities of MDA-MB-231/DDP cells to SQFZ and SQFZ + Cisplatin.

(A) Both MDA-MB-231/DDP and MDA-MB-231/DDP co-cultured with M2-macrophage cells were incubated in SQFZ at 5, 10, 20, 40, 80, 160, or 320 μl/mL for 48 h. (B) MDA-MB-231/DDP and MDA-MB-231/DDP+M2 were treated with cisplatin at 3.75, 7.5, 15, 30, 60, or 120 μmol/L with or without SQFZ (40 μl/mL) for 48 h. Values are shown as the means ± SD from three independent experiments. *p < 0.05 as compared to Cisplatin alone.
