Abstract | BACKGROUND: METHODS: We crossed the PB- hepsin mice with PB-Hi-myc transgenic mouse model of prostate adenocarcinoma and characterized the tumor progression in the resulting PB- hepsin/PB-Hi-myc bigenic mice. RESULTS: We report that PB- hepsin/PB-Hi-myc bigenic mice develop invasive adenocarcinoma at 4.5 months. Further, histological analysis of the 12- to 17-month-old mice revealed that the PB- hepsin/PB-Hi-myc model develops a higher grade adenocarcinoma compared with age-matched tumors expressing only PB-Hi-myc. Consistent with targeting hepsin to the prostate, the PB- hepsin/PB-Hi-myc tumors showed higher hepsin expression as compared to the age-matched myc tumors. Furthermore, endogenous expression of hepsin increased in the PB-Hi-myc mice as the tumors progressed. CONCLUSIONS: Although we did not detect any metastases from the prostates in either the PB- hepsin/PB-Hi-myc or the PB-Hi-myc mice, our data suggests that hepsin and myc cooperate during the progression to high-grade prostatic adenocarcinoma.
