CCNE1 and infection: MSTO-211H cells significantly increased percentages of cyclin E-positive cells 2 days after AdF35/Sur infection (uninfected cells; 0.9 + 0.09%, infected cells; 14.4 + 0.52%), whereas those marginally increased percentages of cells positive for phosphorylated histone H3 (uninfected cells; 1.9 + 0.07%, infected cells; 3.0 + 0.18%), (Fig. 5b).
