Figure 2

(a–d) Plots of dose-responsive cell viability of SK-BR-3 (a), MDA-MB-231-Her2 (b), MDA-MB-231 (c), and MDA-MB-231-Vector cells (d) exposed to free DXR (blue rectangle), GdIII-PCNDXR (red circle), or Her-GdIII-PCNDXR (green triangle) for 24 h at 37 °C. (e–h) Cellular GdIII-uptake profiles of SK-BR-3 (e), MDA-MB-231-Her2 (f), MDA-MB-231 (g), and MDA-MB-231-Vector cells (h) that were incubated for 24 h at 37 °C in the presence of free DOTA-GdIII (left blue bars), GdIII-PCN (middle red bars), and Her-GdIII-PCN (right green bars).
