Immortal Human Prostate Epithelial Cell Cultures as a Prostate Cancer Model
Description of Invention:
The National Institutes of Health has multiple immortalized, malignant, human, adult prostate epithelial cell lines available for license. They are useful as models in epithelial cell oncogenesis studies and in the diagnosis and treatment of prostate cancer.
The cell lines were generated from primary adenocarcinomas of the prostate. Long-term cultures were established by immortalizing cells with human papillomavirus (HPV) transforming proteins. The cultures were characterized and single-cell clones with unique genetic characteristics were selected based on allelic loss of heterozygosity (LOH). Tissue-matched normal cell lines are available also, useful for the appropriate controls.
The invention also encompasses polyclonal and monoclonal antibodies directed to the cell lines, which may be useful as immunotherapeutics.
Applications:
Screening tool to identify novel genes unique to or overexpressed in prostate cancer
Raising of prostate cancer-reactive antibodies, useful as immunotherapeutics or diagnostics
Screen for compounds that kill tumor cells and represent potential therapeutic agents
Identification of prostate cancer antigens to develop recombinant prostate cancer vaccines
