Fig. 3From: ViscumTT induces apoptosis and alters IAP expression in osteosarcoma in vitro and has synergistic action when combined with different chemotherapeutic drugsViscumTT enhances activation of CASP8 and CASP9. FITC-LEHD-FMK and FITC-IETD-FMK staining and FACS analyses represented activity of CASP8 and CASP9 (a). Pre-incubation with ZVAD-FMK pan-caspase inhibitor confirmed caspase-dependent apoptosis induction (b) (mean ± SD, p ≤ 0.05, n ≥ 3, *Fp > 1 = synergism)Back to article page
