Time-dependent effects of Zn2+ chelation or treatment with exogenous Zn2+ to PC3 or C4-2 cell viability (expressed as %-inhibition). Cells were treated with either the cell-impermeable Zn2+-chelator DTPA (50 μM), ZnS04 (50 μM), NaPy (1.2 μM), or NaPy (1.2 μM) + ZnS04 (50 μM) for (A) 24 h or (B) 72 h. Statistical significance, Student’s two-tailed test: *: p<0.05.
