Endometriosis is a complex disease that can develop as a consequence of retrograde menstruation, occurring in association with the cyclic loss of endometrial tissue in primates and humans. In addition, progression of disease parallels a wom…

The endometrial lining of the human uterus is a highly specialized, steroid-sensitive tissue. Throughout the reproductive years, the endometrium undergoes dramatic cycles of growth, differentiation, and breakdown under the influence of ovar…

The human endometrium exhibits regular cycles of growth, differentiation, and breakdown in response to changing levels of ovarian steroids. Following the tissue loss and repair processes of menstruation, rising levels of estradiol initiate …

The cyclic expression of matrix metalloproteinases (MMPs) by human endometrium has been suggested to play a role in the invasive process necessary to establish endometriosis. The ability of progesterone exposure to inhibit endometrial MMP-3…

Endometrial expression of matrix metalloproteinase (MMP)-3, MMP-7 and MMP-11 occurs during menstrual breakdown and subsequent estrogen-mediated growth, but not during the secretory phase. These enzymes are suppressed by progesterone treatme…

Endometriosis is a benign, though aggressive, disease of the female reproductive tract that consists of endometrial stromal and epithelial cells growing at an extrauterine site. Although it is widely accepted that the majority of cases of e…

Environmental contaminants that are known to disrupt steroid action can influence the development of reproductive diseases. Our group has focused on whether 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD or dioxin) can disrupt steroid regulation…

The proper function of the normal human endometrium relies on well organized cell-cell interactions regulated locally by cytokines and growth factors under the direction of steroid hormones. The onset and progression of the disease processe…

Matrix metalloproteinases of the stromelysin family are expressed in the human endometrium as a consequence of cellular events during the menstrual cycle that require extracellular matrix remodeling. We have recently documented the presence…

Surgical modalities such as electrosurgery and lasers have been used for many years to treat endometriosis. They are relatively unselective with wide scatter, however, leading to the potential for significant tissue damage and injury. As an…
