BACKGROUND. The generation of prostatic cell lines provides in vitro models for experimental studies of the pathogenesis of prostate carcinoma. Therefore, we established and characterized a new human prostate epithelial cell line, PEAZ-1 (prostate epithelial Arizona-1). METHODS. The PEAZ-1 cells were grown from a primary human prostate carcinoma specimen obtained from radical prostatectomy. The isolated cells were characterized by immunobiochemistry, immunohistochemistry, and tumorigenicity studies. RESULTS. PEAZ-1 cells are near diploid, tumorigenic, and androgen independent for cell growth. PEAZ-1 cells express N-cadherin, α- and β-catenins, and p120 at cell-cell contacts, cytoplasmic laminin 5, vinculin, paxillin, and phosphotyrosine at focal adhesions, vimentin, and cytokeratins 8 and 18. They do not express plakoglobin, E-cadherin, and PSA, and do not form desmosomes and hemidesomomes. PEAZ-1 respond to ocadaic acid, a pro-apoptotic agent, by expression of p53. CONCLUSIONS. PEAZ-1 cells is a human prostate cancer cell line that has a number of mesenchymal characteristics.
