Figure 7

Overexpressed p53 is active and is made non-functional by HPV 18 E6 in H1299, a p53 and E6 null cell line. (A) H1299 cells were transfected with pC53-SN3 and/or HPV18 E6 plasmids and 18 h post transfection cells were treated with OA. MTT assay was performed after 48 h. Bar represents variations among the wells of an experiment done twice in triplicate. * Indicates P < 0.01 (B) H1299 cells were transfected with pC53-SN3 and/or HPV18E6 plasmids and 18 h post transfection cells were treated with OA for 48 h and western blot was performed for pSer46p53 and p53.(C) Densitometric analysis was performed by normalization with p53 and ratio of pSer53 and p53 was plotted.
