Outline of Final Research Achievements

The purpose of this study is to evaluate the involvement of death receptor (DR) 6 in the pathogenesis of endometriosis. Endometriotic cyst stromal cells (ECSCs) and normal endometrial stromal cells (NESCs) were isolated from ovarian endometriotic tissues and the eutopic endometrial tissues. The expression of DR6 mRNA and protein in ECSCs and NESCs were also examined.DR6 expression was attenuated in ECSCs and in endometriotic tissues, and its expression was upregulated by VPA stimulation. VPA treatment resulted in an accumulation of acetylated histone H4 in the promoter region of the DR6 gene. DR6 knockdown directed the stimulation of cell proliferation and the resistance to apoptosis in NESCs. The present findings suggested that DR6 is involved in the pathogenesis of endometriosis by creating the proliferative and anti-apoptotic characteristics of endometriosis.The results also suggest that histone deacetylase inhibitors are promising agents for the treatment of endometriosis.
