Endometriosis and nuclear receptors

Endometriosis and nuclear receptors By Dr. Youngran Park

It is well recognized that endometriosis is a steroid-dependent disorder. In endometrial stromal cells, progesterone regulates retinoic acid production and action. Retinoids also act via a number of nuclear receptors (NRs) and are involved in normal endometrial function and endometriosis. Estrogen…
