HPV-16 E6 and E7 genes are required to efficiently immortalize a broad spectrum of cell types including cervical keratinocytes. Therefore, the E6/E7 genes can be considered relevant targets for anti-cancer therapy. We produced several engineered hairpin (HP) ribozymes to specifically disrupt HPV-16 E6/E7 mRNA. After extensive biochemical characterization, one anti-E6 HP ribozyme (R434) was sele...

the aim of this study was to ascertain the prevalence of human papillomavirus (hpv) 16/18 in oral squamous cell carcinoma (oscc) and normal oral mucosa in iranian individuals with oscc and their association with various risk factors. the investigation followed a hospital-based case-control design. cases were individuals with diagnosed oscc, age- and sex-matched with controls. sixty-six paraffin...

A mouse model of high-risk human papillomavirus infection was developed in which human papillomavirus (HPV) type 16 DNA was inoculated into human foreskin grafted to the skin of severe combined immunodeficient (scid) mice. Grafted skin contained human epidermis and dermis and, like normal human skin, expressed involucrin in differentiating keratinocytes. HPV type 16 DNA, attached to gold partic...
