Comparing p53 protein levels and p53 transcriptional activity in cells expressing E6-GFP from HPV types 18, 33, and 33 variants. Panel A: Western blot analysis of p53 and E6-GFP. Panel B: p53 transcriptional activity as determined by measuring luciferase activity in cells co-transfected with the p53 responsive p21-luciferase reporter plasmid.
