Abstract: Endometriosis is a benign gynecologic disease, affecting women of reproductive age associated with chronic pelvic pain. Activation of NF-?B has been implicated in the early development as well as processes of endometriosis lesions. In vitro and in vivo studies show that NF-?B mediated gene transcription promotes immune and inflammatory response, modulates cell proliferation, apoptosis, adhesion, invasion, and angiogenesis of endometriotic cells which may attribute to changes of peripheral nerves and the peritoneal environment in endometriosis lesions and cause pain. This may indicate a new target for the cure of endometriosis pain.
