Figure 4From: CD40 ligand induced cytotoxicity in carcinoma cells is enhanced by inhibition of metalloproteinase cleavage and delivery via a conditionally-replicating adenovirusMembrane-bound expression of CD40L induces apoptosis in CD40-positive carcinomas. EJ, AGS and HeLa cells were infected with 100 MOI RAdMock, RAdCD40L or RAdncCD40L, or treated with soluble CD40L (1 μg/ml) or left without treatment for 48 hours. Apoptotic cells were assessed by staining with Annexin V-APC and analysis by flow cytometry. Results are a mean of triplet samples ± SD. Two-tailed t-test RAdL vs. RAdncL: EJ, p = 0.0014; AJS, p = 0.0022; HeLa, p = 0.6560.Back to article page
