To assess the infection efficiency of the virus, a parallel set of cultures were infected with 100pfu/cell of virus (Su et al., 1998b, 1998c). The viral infection efficiency in cultures ranged between 92-100% (unpublished data). Therefore, the growth inhibition and reduction in colony formation in cancer cells is a direct consequence of expression of the mda-7 transgene. In stark contrast, no discernable effect was evident in normal human mammary epithelial, human skin fibroblast or an immortalized (SV40 containing) human breast epithelial cell line (HBL-100) infected with 100pfu/cell of Ad.mda-7 S, even though replicate cultures inf
