Effect of Z-VAD-FMK on apoptosis induced by hypericin-mediated photodynamic therapy. Apoptosis induced by caspase activation due to hypericin-mediated photodynamic therapy together with 590 nm LED was inhibited by the pan-caspase inhibitor, Z-VAD-FMK. The Z-VAD-FMK improved the survival rate by inhibiting the apoptosis pathway induced by hypericin-mediated photodynamic therapy
