Effects of PTE on HCMV-induced expression of p16, p21 and p53. A Serum-starved WI-38 cells were infected with the indicated MOI of HCMV, and the samples were harvested at 5 dpi to analyse the expression levels of the above molecules using Western blotting. GAPDH was used as the loading control. Representative images shown here were selected from three independent experiments. B Quantitative analysis of the protein levels of p16, p21 and p53. The sample without HCMV infection was used as the mock control, ^#P < 0.05 versus the mock control, ^##P < 0.01 versus the mock control, ^###P < 0.001 versus the mock control. *P < 0.05 versus the HCMV + PTE group
