Endometriosis is one of the most common gynecological diseases in women of reproductive age. Although cyclooxygenase (COX)-2 inhibitors are effective in the treatment of endometriosis, the adverse cardiovascular effects associated with these inhibitors have limited their use. Microsomal prostaglandin E synthase-1 (mPGES-1) is an inducible enzyme downstream of COX-2 in prostaglandin E(2) biosynthesis. Previously, we developed mPGES-1 knockout mice (mPGES-1(-/-)) and have identified for the first time the roles of ectopic lesion- and host-associated mPGES-1 in angiogenesis and the growth of endometrial tissues. When mPGES-1(-/-) endometrial fragments were implanted into wild type (WT) mice (mPGES-1(-/-)?WT), or WT fragments implanted into mPGES-1(-/-) mice (WT?mPGES-1(-/-)), the growth of the implants was suppressed at days 14 and 28 after implantation, compared toWT?WT transplantation. An even greater degree of suppression was observed in mPGES-1(-/-) endometrial fragments implanted into mPGES-1(-/-) mice (mPGES-1(-/-)?mPGES-1(-/-)). After WT-WT implantation, mPGES-1 expression was localized at the border of the implanted endometrial tissues. Microvessel density, determined by CD31 immunostaining, was markedly suppressed in the mPGES-1(-/-) endometrial fragments implanted into mPGES-1(-/-) mice, with some suppression also observed in the mPGES-1(-/-)?WT and WT?mPGES-1(-/-) groups. The expression of vascular endothelial growth factor (VEGF-A) was significantly reduced in mPGES-1(-/-) endometrial tissues implanted into mPGES-1(-/-) mice at days 14 and 28, in comparison to the WT?WT group. These results suggested that mPGES-1 enhanced angiogenesis and growth of the endometrial implant, and indicate that mPGES-1 may be a good therapeutic target for endometriosis.
