c-Fos-Regulated Matrix Metalloproteinase-9 Expression is Involved in 17ß-Estradiol-Promoted Invasion of Human Endometrial Stromal Cell.
This study investigates the effect of 17β-estradiol (E2) on human endometrial stromal cell (HESC) invasion and the role of c-fos and matrix metalloproteinase-9 (MMP-9) in mediating the biological function of 17β-E2. It is found that 17β-E2 promotes not only HESC invasion, but also c-fos and MMP-9 expression in HESC. Further experiments demonstrate that the estrogen receptor inhibitor ICI 182780 and siRNA-mediated c-fos or MMP-9 knockdown are able to block the effect of 17β-E2 on HESC invasion. Moreover, siRNA-mediated c-fos knockdown suppresses the effect of 17β-E2 on MMP-9 expression. Our results indicate that 17β-E2-induced HESC invasion is dependent on c-fos-mediated MMP-9 expression. These findings facilitate our understanding on the pathogenesis of endometriosis and may provide data potentially useful for the development of new treatment modalities for better management of endometriosis.
