Figure 2. RSV Inhibited Cell Growth in Skin Cancer Cells, A431. Cells were infected with MOI of 1 and 3 of RSV for 24, 36, and 48 hours. The inhibitory effect of RSV on the growth of A431 cells were measured by MTT assay. RSV induced cell growth inhibition in a concentration- and time-dependent manner. The results (Mean ± SD) represent at least 3 separate experiments. Differences between RSV infected and non-infected cells were statistically analyzed by ANOVA (*** = P < 0.001).
