Cytotoxicity of M002 in human and murine tumor cells at 48 h post-infection. Plates of human breast cancer cells MDA-MB-361 (a) or murine mammary carcinoma cells SCK (b), and 4T1 (c) were infected with the indicated viruses at an MOI of 1 (black bars) or 10 (gray bars) PFU/cell. At 48 h post-infection, cell viability was assayed by MTT assay. Shown are the averages of quadruplicate determinations, normalized to uninfected cells and expressed as the proportion viable cells.
