A novel type of human papillomavirus associated with genital neoplasias

The role of human papillomaviruses (HPVs) in the development of genital neoplasias has been well documented. The genomes of two HPV types, HPV16 and HPV18, have been found to be associated with about 70% of invasive carcinomas of the uterine cervix. As, under non-stringent hybridization conditions, HPV DNA sequences have been detected in about 90% of cervical carcinomas, it seems likely that additional HPV types are associated with these tumours. Here we report the molecular cloning and characterization of a novel HPV type, tentatively named HPV33, whose sequences have been detected in 4-8% of biopsies of genital intra-epithelial neoplasias and cervical invasive carcinomas, usually as free monomeric or oligomeric molecules. However, in one specimen of vulvar Bowen's disease, HPV33 DNA sequences were integrated in the host-cell genome. Thus, HPV33 probably represents an additional type of potentially oncogenic genital HPV.

A common function for polyoma virus large-T and papillomavirus E1 proteins?

Nucleotide sequencing has revealed a common genetic organization for three papillomaviruses: BPV-1 (bovine papillomavirus type 1), HPV-1 (human papillomavirus type 1a) and HPV-6 (human papillomavirus type 6b). Several open reading frames, corresponding to as yet uncharacterized proteins, were observed in these genomes in the region that is required for oncogenic transformation by BPV-1 and for plasmidial maintenance of its genome. The longest of these frames, E1, is also the most conserved between the three viruses; we have compared the amino acid sequence of its putative product ('E1 protein') with those of the large-T proteins of three polyoma viruses and report here significant homologies in their carboxy-terminal halves, extending for over 200 amino acids. Moreover, similar secondary structures were predicted in this region, especially in two blocks of homologous residues, which correspond in the large-T proteins of polyoma and simian virus 40 (SV40) viruses to sites involved in the ATPase and nucleotide-binding activities. These observations suggest that the papillomavirus E1 proteins might have a function in common with the polyoma virus large-T proteins (which are required for the initiation of viral DNA replication). As it was suggested recently that the E1 gene product is involved in maintaining the BPV-1 genome as a plasmid in transformed cells, we speculate that the structural features conserved in these otherwise very different viruses are general characteristics of eukaryotic proteins involved in the control of DNA replication.
