We describe a case of a 67-year-old male with multiple erythematous, hyperkeratotic, and ulcerated lesions that occurred 10 years before patient’s observation, increasing in size and number over the years. Particularly, the widest lesion is hyperkeratotic and exudative plaque on the trunk, focal ulcerated, sized 11 cm × 8 cm [Figure 1]. Other lesions were observed on the trunk and ears. However...
Human papillomavirus (HPV) type 16 is the major cause of cervical carcinoma, the incidence of which is decreasing in western countries. In Finland the incidence is, however, increasing in women aged <40 years, but possible underlying changes in HPV-16 epidemiology are unknown. To assess incidence trends of HPV infections, paired sera from a random sample of 8000 women with two pregnancies/sera ...
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...
Genital human papillomavirus (HPV) infection is common and the majority of infected individuals successfully deal with this virus. Clearance of HPV is presumably mediated by T cells but HPV-16-specific T-cell memory was usually detected in patients with progressive disease and not in healthy subjects, suggesting that HPV-immunity comes too late. We now show the presence of HPV-16 E6-specific me...
BACKGROUND Cervical cancer has been shown to be highly associated with human papillomavirus (HPV) infection. The viral oncogenes E6 and E7 are constantly expressed by the tumor cells and are therefore potent targets for therapeutic genetic vaccination. In the present study, it was investigated the potential effect of HPV-16 E6, E7 and L1 co-administration to activate specific cytotoxic T lympho...
Human papillomavirus (HPV) infection, in particular that by HPV type 16, is positively associated with cervical/genital cancer. In contrast, human adeno-associated virus (AAV) infection is negatively associated with these same cancers. AAV has also been found to inhibit the oncogenic properties of a variety of DNA viruses, including bovine papillomavirus type 1, a relative of HPV-16. Taken toge...
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...
High-risk human papillomavirus (HPV) especially HPV-16 and HPV-18 types are speculated to be important risk factors in non-smoking associated lung cancer in Asia. Increasing evidence has demonstrated that HPV oncoproteins may contribute to lung tumorigenesis and cell transformation. Importantly, HPV 16/18 E6 and E7 oncoproteins can mediate expression of multiple target genes and proteins, such ...
