Fig. 10: Immunoblots showing the differential effects of [L2Cu3]6+and [L2Zn3]6+ treatment of HCT116 cancer cells and ARPE-19 non-cancer cells on key cellular proteins associated with cellular and metabolic stress.

Representative immunoblot images of the indicated proteins following cell exposure to 5 µM [L2Cu3]6+ or [L2Zn3]6+ for 40 h. Tyrosine phosphorylated proteins are indicated using a pan- phospho-Tyr antibody; β-actin as a loading control. Similar results were obtained in a minimum of n = 2 independent experiments.
