Tumor Progression in Prostate Cancer

Research in this laboratory utilizes the Dunning R-3327 rat dorsal prostatic adenocarcinoma system. This spontaneously developing cancer consists of several well defined sublines which exhibit varying stages of tumor progression similar to that of human prostate cancer. Our study of prostate cancer has demonstrated correlations between metastatic oncogene expression (ras family) and cellular differentiation (retinoic acid, diflouromethyl ornithine). The metastatic process involves the ability of a proliferative cellular mass to be motile, which suggests a deregulation of genetic and cellular controls. To this end, we have utilized invasion, chemoinvasion and adhesion assays as a means of distinguishing the metastatic phenomenom. In addition, confocal laser microscopy has been utilized to elucidate changes in the distribution of cytoskeletal proteins (actin, alpha-actinin, vinculin,vimentin) as a means of characterizing the metastatic process. In sum, this laboratory seeks to further characterize genotypic and phenotypic entities associated with tumor progression of the prostate as well as to demonstrate how differentiation therapy could be utilized as a tool for tumor suppression.
