| Outline of Final Research Achievements |
We demonstrated that ER beta and estrogen-producing/metabolizing enzymes were expressed in human urinary urothelial carcinoma, and ER beta might inhibit migration of the carcinoma cells as well as the expression level of MMP11 in the cells. On the other hand, we also confirmed that the expression levels of these enzymes were significantly and inversely correlated with pT stage. Therefore, we conclude that estrogen synthesized in situ could repress development of urinary urothelial carcinoma cells via ER beta, but the lower expression levels of these enzymes in advanced pT stage cases might result in decreased estrogen production and progression and invasion of carcinoma cells.
