Effect of hormonal agents on monocyte chemotactic protein-1 expression by endometrial epithelial cells of women with endometriosis.

OBJECTIVE: To assess whether hormonal agents used in the medical treatment of endometriosis, such as danazol and GnRH agonist, exert direct regulatory action on monocyte chemotactic protein-1 (MCP-1) expression by endometrial epithelial cells. DESIGN: Primary cultures of epithelial cells isolated from human endometrium were exposed to different concentrations of cytokines and steroid hormone analogs. Expression of MCP-1 was analyzed at the levels of protein and messenger RNA. SETTING: Gynecology clinic and laboratory of endocrinology of reproduction. PATIENT(S): Women presenting for infertility or pelvic pain in whom endometriosis was diagnosed by using laparoscopy. INTERVENTION(S): Endometrial tissue biopsy performed at laparoscopy. MAIN OUTCOME MEASURE(S): Secretion of MCP-1 protein was measured by using enzyme-linked immunosorbent assay, and mRNA steady-state levels were measured by performing Northern blot analysis. RESULT(S): Buserelin acetate, a GnRH agonist (0.1-10 ng/mL), had no significant effect on MCP-1 expression, whereas danazol (10(-7)-10(-5) M), a testosterone analog, and dexamethasone, an anti-inflammatory glucocorticoid hormone (10(-12)-10(-6)M), showed a direct and a dose-dependent inhibitory effect on MCP-1 expression. This effect occurred at the level of protein and mRNA. CONCLUSION(S): The findings of the study may affect understanding of the mechanisms by which hormonal treatments act on endometriosis and influence its clinical manifestations.[1]
