Figure 1From: Increased ATP generation in the host cell is required for efficient vaccinia virus productionWestern blotting analysis of ND4 expression in vaccinia virus infected cells. (A) The HeLa cells were infected with MOI = 1 (or 5 or 20) of vaccinia virus for various time periods, as indicated. ND4 expression (marked by an arrow) was analyzed by Western blotting. ERK2 protein was served as a loading control. Occasionally, two non-specific bands (one larger and one smaller than ND4, indicated by thin lines) were detected in the samples. (B) ND4 was also up-regulated in HuH7 cells after vaccinia virus infection. The ND4 protein is marked by an arrow while a non-specific band is indicated by a thin line.Back to article page
