Research Abstract

We generated a transgenic rat with the SV40 T antigen under probasin promoter control, allowing prostate-specific gene expressions. Males demonstrate atypical epithelial cell proliferation in the prostate from 4 weeks of age and develop prostate carcinomas at 100% incidence before they are 15 weeks old. From the transgenic rat of 55 week-old, we established a transplanted tumor in nude mice with castration treatments. And then, we have tried to established cell lines from the nude mice tumor. Finally we established 3 cell lines. One cell line designated PCai-1 shows charcoal treated FBS insensitive growth, and two other cell lines PCai-2 and PCai-3 are sensitive for the charcoal treatment FBS with stopping growth. Characteristic gene expression profiles have been obtained for each 3 cell lines. These cell lines may be useful to study mechanisms of progression of prostate cancers, and to study chemo-prevention of prostate cancers. Furthermore, we established new cell lines from the non-castrated androgen dependent transplanted tumors. These cells had the stem cell like characters such as asymmetric tumor growth and CD133 expression.
