In certain aspects, the invention relates to methods of treating proliferative cervical disorders (such as cervical cancer and cervical dysplasia) and treating virus infection by administering artemisinin-related compounds. In certain aspects, the invention relates to methods of treating a tumor induced by an oncogenic virus, methods of killing or inhibiting a squamous cell carcinoma, and methods of inhibiting the replication of a virus, by administering artemisinin-related compounds.

Use of artemisinin for treating tumors induced by oncogenic viruses and for treating viral infections

The present invention is directed towards methods of culturing non-keratinocyte epithelial cells, with the methods comprising culturing non-keratinocyte epithelial cells in the presence of feeder cells and a calcium-containing medium while inhibiting the activity of Rho kinase (ROCK) in the feeder cell, the non-keratinocyte epithelial cells or both during culturing.

Immortalization of epithelial cells and methods of use

In certain aspects, the invention relates to methods of treating proliferative oropharyngeal cancer, laryngeal cancer and esophageal cancer by administering artemisinin-related compounds.

Seven polyclonal and monoclonal antibodies were characterized for their ability to react specifically with either conformational or non-conformational epitopes of the HPV-1 virion. Using these antibodies, it was shown that the HPV-1 L1 protein (when expressed by an SV40 vector in cos cells) displayed conformational epitopes characteristic of intact viral particles. In addition, the L1 capsid protein was translocated normally into cell nuclei, was of appropriate size (57kD), and could be isolated in native form by immunoprecipitation techniques. Most importantly, the screening of expressed papillomavirus capsid proteins for reactivity with conformation-dependent antibodies represents a new, general methodology for ensuring that such proteins will be suitable for use in vaccine development or in the serologic detection/typing of human papillomavirus infections.

Novel acetone- or alcohol-fixed viral capsid proteins, bacteria-containing, and papillomavirus L1-GST fusion proteins are described. These proteins are useful in vaccine preparation and as diagnostics.

Stable (fixed) forms of viral capsid proteins, and viral capsid protein fusions, preferably papillomavirus L1 proteins, and uses thereof

Recombinantly produced L1 major capsid proteins which mimic conformational naturalizing epitopes on human and animal papilloma virions including canine and equine papilloma virions are provided. These recombinant proteins are useful as vaccines for conferring protection against papillomavirus infection. Antibodies to the recombinant protein are also provided. Such antibodies are useful in the diagnosis and treatment of viral infection.

Formalin-treated human papillomavirus L1 protein vaccine

Recombinantly produced L1 major capsid proteins which mimic conformational naturalizing epitopes on human and animal papilloma virions including canine and equine papilloma virions are provided. These recombinant proteins are useful as vaccines for conferring protection against papillomavirus infection. Antibodies to the recombinant protein are also provided. such antibodies are useful in the diagnosis and treatment of viral infection.

Formalin-Inactivated human papillomavirus L1 protein vaccine

Protecting against canine oral papillomavirus (copy)

A process of immortalizing cells with isolated HPV-16, 18, 31, 33 or 35 E6 and E7 genes or the E7 gene alone to produce non-tumorigenic immortalized cell lines which retain the differentiated phenotypic characteristics of the parent cells.
