| Research Abstract |
Endometriosis is the intractable disorder characterized by the presence of endometrial tissue outside of the uterine cavity. Distinct endometriosis-like lesions in our experimental internal bleeding mouse model exhibited the expression of high levels of inflammation factors. To identify changes in protein levels in endometriosis-like lesions, protein profile changes were compared with control (no bleeding) mice. Cell lysates from lesions from uOVX and control mice were analyzed by 2-D gel electrophoresis, followed by MALDI-TOF MS. The level of alpha1-antitrypsin (a1-AT) is decreased in lesions from mice that underwent uOVX. In cultured stromal cells, a1-AT inhibited the expression of inflammation and cell survival factors. Reduced a1-AT levels may exacerbate local inflammation, suggesting the possible involvement of a1-AT in the pathophysiology of endometriosis.
