| Outline of Final Research Achievements |
To uncover the mechanism by which human prostate cancer progresses, we performed a genetic screen for regulators of human prostate cancer progression using the Drosophila accessory gland, a functional homolog of the mammalian prostate. Cell growth and migration of secondary cells in the adult male accessory gland were found to be regulated by Drosophila homologues of regulators of human prostate cancer progression. Using this screening system, we identified three genes that promoted growth and migration of secondary cells. The human homologues of these candidate genes were expressed in human prostate cancer cells and promoted replication and invasiveness in these cells. These findings suggest that the development of the Drosophila accessory gland and human prostate cancer cell growth and invasion are partly regulated through a common mechanism. The screening system using the accessory gland can be a useful tool for uncovering the mechanisms of human prostate cancer progression.
