Using RNA aptamers to study cellular targets of human papilloma virus oncoproteins in a human skin model

Human papilloma viruses HPV16 and 18 are the major causative agents of a range of anogenital and oropharyngeal cancers, with HPV16 associated with the majority of all cervical carcinomas. Transformation results from the expression of the E6 and E7 proteins, resulting in deregulation of the cell cycle and cellular proliferation. In studies currently funded by Yorkshire Cancer research, we are using a novel strategy using RNA aptamers as molecular probes to specifically target and block each of the E6/E7 interactions. We have generated a large number of RNA aptamers that bind to the E6 and E7 proteins. Some of these disrupt interactions with as yet undefined cellular targets. We propose to characterise a number of these interactions in vitro, and extend our studies into a human skin model.
