Cytotoxic effect of AdTRAIL (MOI 10) alone or in combination with different concentrations of DOX, PTX, CDDP or 6 Gy irradiation in H460 cells at 3 days postinfection. Values are the mean (n=3)±s.d. The P-values were calculated by comparing the slopes of the multiple regression of ln (viability2) of H460 cells treated with AdTRAIL alone or combined with DOX, PTX or CDDP vs ln (drug conc.²) by Student's t-test. For the irradiated groups, the P-value was calculated by comparing the viability of cells treated with AdTRAIL alone or in combination with 6 Gy irradiation using Student's test.
