| Outline of Final Research Achievements |
Endometriosis, a disease affecting 3-10% of women of reproductive age, is characterized by the ectopic growth of endometrial tissue. Histologically, this disease is characterized by endometrial gland and stroma with surrounding dense fibrous tissue. During the development of endometriotic lesions, excess fibrosis may lead to scarring and to alteration of the tissue function. To understand the pathogenesis of endometriosis, we established an in-vitro model of endometriosis-associated fibrosis. We found that the activation of the phosphatidylinositol-3 kinase-Akt-mammalian target of rapamycin-mediated signaling pathway is involved in this mechanism. We also evaluated some agents that act on this signaling pathway for the medical treatment of endometriosis.
