Abstract: According to the invention, parvoviruses such as the adeno-associated virus Type 2 (AAV2) are found to be oncolytic, selectively mediating apoptosis in cancer cells and their precursors, while leaving healthy cells intact. The invention also includes a method of killing cancer and other neoplastic and preneoplastic cells by administrating to said cells the AAV2 proteins Rep78 or Rep 68, expression constucts encoding the same, or pharmaceutical compositions comprising the same.

Abstract: According to the invention, parvoviruses such as the adeno-associated virus Type 2 (AAV2) are found to be oncolytic, selectively mediating apoptosis in cancer cells and their precursers, while leaving healthy cells intact. The invention thus comprises a method of killing cancer and other neoplastic and preneoplastic cells by administration of AAV2 virus, viral particles, products or replication incompetent vectors derived there from to said cells, and pharmaceutical compositions comprising the same.

Abstract: This invention relates to infectious chimeric papillomaviruses, and especially those where the early genes are from human papillomavirus (HPV) 18, and the late genes are from another HPV. Also presented are methods of culturing the virus in raft cell cultures, and to assays utilizing these chimeric viruses.

Abstract: The present invention provides a process of biosynthesizing papillomavirus by inducing complete differentiation of an epithelial cell that contains papillomavirus DNA. Complete differentiation is induced by exposing epithelial cells to a protein kinase C inducer. Assays for screening agents that modify papillomavirus biosynthesis, determining the papillomavirus infectivity of epithelial cells, detecting the presence of anti-papillomavirus antibodies and vaccinating against papillomavirus infection are also provided.

Abstract: Expression vectors that include reporter genes and an operable regulatory region containing a promoter and E2 binding sites of papillomavirus (PV), are used to detect and/or titer papillomavirus by quantitative or qualitative methods.

Abstract: Artificial systems for the production of infectious human papillomavirus allow development of diagnostic and therapeutic strategies based on replication and infectivity studies for diseases caused by these viruses. The artificial introduction of papillomavirus genomic DNA into an epithelial cell line. In particular, HPV type 18 genomic DNA is transfected into primary keratinocytes. Transfection is followed by clonal expansion of the transfected cells, and induction of epithelial stratification and differentiation in organotypic cultures resulting in the synthesis of virions. Virus particles synthesized were approximately 50 nanometers in diameter as observed by electron microscopy. In particular HPV18 virions produced by the system and purified by an isopycnic gradient were capable of infecting keratinocytes.
