Abstract

Herein, murine prostate cancer cell lines, generated via selective transduction with a single oncogene (c-Myc, Ha-Ras, and v-Src), demonstrated oncogene-specific prostate cancer molecular signatures that were recapitulated in human prostate cancer, and developed lung metastasis in immune competent mice. Interrogation of two independent retrospective cohorts of patient samples using the oncogene signature demonstrated an ability to distinguish tumor from normal prostate with a predictive value for prostate cancer of 98 – 99%. In a blinded study, the signature algorithm demonstrated independent substratification of reduced recurrence free survival by Kaplan-Meier analysis. The generation of new oncogene-specific prostate cancer cell lines that recapitulate human prostate cancer gene expression, that metastasize in immune-competent mice, are a valuable new resource for testing targeted therapy while the molecular signatures identified herein provides further value over current gene signature markers of prediction and outcome.
