Outline of Final Research Achievements

Estrogen contributes toward the growth and development of endometrial cancer. The steroid sulfatase pathway may be related to estrogen-dependent biological characteristics. However, the role of the steroid sulfatase pathway and the possible effect of steroid sulfatase inhibitor on endometrial cancer are unclear.
Cell proliferation in endometrial cancer cells was significantly decreased by steroid sulfatase inhibitor in co-culture with stromal cells. Estrogen receptor and steroid sulfatase mRNA levels were significantly higher in co-culture with stromal cells. These data indicated the local biosynthesis of estrogens through the steroid sulfatase pathway and tumor-stromal interactions. Steroid sulfatase inhibitor may be a promising novel endocrine therapy for endometrial cancer. Our results may provide important information on the metabolism and synthesis of intratumoral estrogens with regard to the etiology and progression of endometrial cancer.
