<p><b>A:</b> Cell viability was measured using the CCK-8. After induction with hTNF-α (25 ng/ml) and CHX (10 µg/ml) for 15 hours, the hHO-1 group had a lower percentage of viable cells. <b>B and C:</b> FACS analysis of hTNF-α and CHX-mediated apoptosis in fibroblasts. Apoptosis was analyzed using annexin V staining. The numbers indicate the proportion of apoptotic cells in the NPCCs after 15 hr incubation with hTNF-α and CHX. <b>D:</b> Activities of caspase 3/7 were measured in fibroblasts. Human HO-1 protected transgenic fibroblasts from apoptosis after 15 hr of incubation with hTNF-α and CHX. After Zn(II)PPIX treatment, Ad-hHO-1 increased activity of caspase 3/7. Each experiment was repeated three times. (* p<0.05, ** p<0.01, *** p<0.001, NT: no treatment).</p
