HPV16 E6/E7 oncoprotein expression correlates with cIAP2 expression in squamous cell carcinoma cells. cIAP2 expression in HPV16 E6/E7 positive SCC-143 cells was measured by a RT-qPCR normalized against GAPDH transcripts (p = 0.0383) and b Western Blotting for pRb, p53 and cIAP2 protein levels in SCC-143 transfected with an empty (∅) or HPV16 E6/E7 vector. β-actin levels were used as loading control. c The bar graph represents the densitometric analysis of three independent experiments (p = 0.0115, t student) (*p ≤ 0.05; t-student test)
