OBJECTIVE: To evaluate the effect of lipopolysaccharide (LPS) on the expression of tumor necrosis factor alpha (TNFalpha) and interleukin-8 (IL-8) protein in endometriotic stromal cells (ESC) and their effect on the proliferation of ESC. DESIGN: Prospective study. SETTING: Department of Obstetrics and Gynecology, Tottori University Hospital, Yonago, Japan. PATIENT(S): Seventeen patients who underwent laparoscopic surgery. INTERVENTION(S): Endometriotic stromal cells were obtained from chocolate cyst linings of the ovary. MAIN OUTCOME MEASURE(S): We determined the effect of LPS on the production of TNFalpha and IL-8 and the effect of IL-8 antisense oligonucleotide and nuclear factor-kappaB (NF-kappaB) inhibitor on IL-8 production using ELISA. TNFalpha production was examined by immunocytochemical staining. We determined the effect of LPS and the effect of IL-8 antisense oligonucleotide and NF-kappaB inhibitor on LPS-promoted ESC proliferation. RESULT(S): LPS-stimulated ESC produced significant amounts of TNFalpha and IL-8 in a dose- and time-dependent fashion. Adding LPS promoted ESC proliferation. Anti-TNFalpha antibody and anti-IL-8 antibody inhibited the stimulatory effects of LPS. IL-8 antisense oligonucleotide and NF-kappaB inhibitor significantly decreased LPS-induced IL-8 protein production and LPS-induced ESC proliferation. CONCLUSION(S): Pelvic inflammation may promote the progression of endometriosis.
