Research Abstract |
The mechanism of prostate carcinogenesis is not elucidated yet. In this study, we established a new experimental procedure for analyzing prostate carcinogenesis using in vitro three dimensional culture(3D) assays. Using this method, we showed a direct role for decreased annexin A1 expression in prostate carcinogenesis via the up-regulation of IL-6. Furthermore, we indicated an important role for androgen receptor(AR) in forming normal acinar structure in 3D culture. We reported several mechanisms of prostate carcinogenesis by regulating AR expression and its activity.
