Figure 9From: Reovirus exerts potent oncolytic effects in head and neck cancer cell lines that are independent of signalling in the EGFR pathway Reovirus induced cell death is not apoptotic in SCCHN cells. A. SCCHN cells shown were infected with reovirus (MOI 1) using viral stocks at 3.7×109 TCID50/ml and Jurkat cells were treated with 10 μM camptothecin (campto). Lysates were resolved on 10% NuPage Novex Bis Tris gels and probed for pro-caspase 3 cleavage. B. Cal27, C. SIHN 5B, D. HN3, E. HN5 and F. 011A were treated with pan-caspase inhibitor (ZVAD, 200 μM) for 2 hr prior to either TNFα-related apoptosis inducing ligand treatment (TRAIL 100ng/ml) or reovirus infection (MOI 10) using viral stocks at 1.9 × 109 TCID50/ml. Cell survival was assessed by MTT assay at 96 hours post-infection. Means are from at least 3 independent experiments and error bars represent SEMs.Back to article page
