Human papillomavirus type 16 <i>E6</i> and <i>E7</i> oncogenes abrogate radiation-induced DNA damage responses <i>in vivo</i> through p53-dependent and p53-independent pathways

Abstract excerpt

E6 and E7 oncoproteins from high risk human papillomaviruses (HPVs) transform cells in tissue culture and induce tumors in vivo. Both E6, which inhibits p53 functions, and E7, which inhibits pRb, can also abrogate growth arrest induced by DNA-damaging agents in cultured cells. In this study, we have used transgenic mice that express HPV-16 E6 or E7 in the epidermis to determine how these two proteins modulate DNA...
