Inhibition of Fas-mediated cell death upon infection with Ad2

Cell line	Mock	Ad2	H2dl801
MCF-Fas	55.2  ±  1.4	11.0  ±  3.9	43.1  ±  3.3
MCF-FasVI	52.9  ±  2.7	2.2  ±  6.3	36.6  ±  3.3
MCF-FasBcl2	25.4  ±  2.9	5.8  ±  3.8	12.5  ±  6.4

Viability of cells in the absence and presence of Fas antibodies was determined in triplicates by the MTT assay and the percentage of Fas-mediated cell death was calculated relative to that of untreated cells (see Materials and Methods). Data represent the mean ± SEM of five experiments.
