Di(2-ethylhexyl) phthalate (DEHP) is a plasticizer ubiquitously found in the environment. Due to its biological activity, it is classified as an endocrine-disrupting chemical and reproductive toxicant. DEHP and its metabolites have been det…

BACKGROUND: Chronic pelvic pain (CPP) is a common symptom of endometriosis. Women with endometriosis are also at a high risk of suffering from anxiety, depression, and other psychological disorders. Recent studies indicate that endometriosi…

Mono(2-ethylhexyl) phthalate (MEHP) is the most studied metabolite of di(2-ethylhexyl) phthalate (DEHP), a phthalate found in cosmetics, flooring, paints, and plastics products, including toys and medical tubing. Humans are frequently expos…

Fibroid etiology is poorly understood but is likely hormonally mediated. Therefore, we evaluated associations between midlife phthalates (hormone-altering chemicals) and prior fibroid diagnosis, and considered differences by weight gain sta…

Uterine fibroids (leiomyomas) are present in >75% of women and can cause serious morbidity. They are by far the leading cause of hysterectomy. Fibroids are a complex mixture of cells that include fibroblasts and smooth muscle cells. Rich in…

PROBLEM: Perturbations in T-helper lymphocyte profiles have previously been associated with endometriosis related subfertility and conception failure. Hence a retrospective in vitro study was conducted to evaluate the relationship between T…

Basigin is a highly glycosylated transmembrane protein that was originally identified as a product of tumor cells. Basigin is a potent inducer of matrix metalloproteinases (MMPs) and angiogenic factors such as vascular endothelial growth fa…

Ample evidence suggests that environmental and occupational exposure to bisphenol A (BPA) and phthalate, two chemicals widely used in the plastics industry, disturbs homeostasis of innate immunity and causes inflammatory diseases. However, …

Endometriosis, defined as growth of the endometrial cells outside the uterus, is an inflammatory disorder that is associated with chronic pelvic pain and infertility in women of childbearing age. Although the estrogen-dependence of endometr…

BACKGROUND: Endometriosis is a gynecological condition that is characterized by extreme abdominal pain and also decreased fertility. Regulatory T cells (Tregs) have immunosuppressive activity critical for embryonic implantation and likewise…

CONTEXT: Uterine remodeling is highly dependent on the glycosylated transmembrane protein extracellular matrix metalloproteinase (MMP) inducer (EMMPRIN). Previous studies indicate estradiol can increase EMMPRIN expression in uterine cells a…

Endometriosis is a gynecological condition that is characterized by extreme abdominal pain and also decreased fertility. Regulatory T cells (Tregs) have immunosuppressive activity critical for embryonic implantation and likewise the accepta…

Extracellular matrix metalloproteinase inducer (EMMPRIN; BSG) regulates tissue remodeling through matrix metalloproteinases (MMPs). In human and non-human primates, endometrial remodeling is important for menstruation and the pathogenesis o…

PROBLEM: Endometriosis is the presence of ectopic uterine endometrial tissue in the peritoneal cavity. Peritoneal fluid samples of women with endometriosis show elevated interleukin-1 (IL-1)beta, tumor necrosis factor (TNF)-alpha and transf…

OBJECTIVE: Granulocyte macrophage colony-stimulating factor (GM-CSF) has been related to macrophage recruitment and activation and has been identified in the human endometrium. We determined whether adenomyosis expresses GM-CSF, and if pres…

OBJECTIVES: Basic fibroblast growth factor (bFGF) is an angiogenic growth factor present in human endometrium and myometrium. Women with leiomyoma-related abnormal uterine bleeding have local dysregulation of bFGF and its type 1 receptor (F…

OBJECTIVE: To test the hypothesis that prolactin (PRL) acts as a mitogenic growth factor for human leiomyoma and myometrial cells. METHODS: To test this hypothesis, we performed three different types of experiments. First, we assessed whet…
