UV-irradiated CVB3 stimulates early-phase phosphorylation of ERK1/2. HeLa cells were infected with either wild-type virus or UV-irradiated virus, and 10 min and 9 h after infection (pi) cell lysates were harvested and Western blotting was performed to determine ERK activation. To verify equal loading, Western blotting was performed with an anti-ERK1/2 antibody. Data are from one of two different experiments. Sham is as defined for Fig. 1.
