To determine whether cancer antigen-125 (CA-125) levels are increased in women with endometriosis, especially in those with endometriomas (OMAs), deep infiltrating lesions (DIE), and superficial endometriosis (SUP) compared with controls without endometriosis in a large cohort of operated women.', 'Cross-sectional study (Canadian Task Force classification II-2).', 'Tertiary-care university hospital.', 'Four hundred six women with histologically proven endometriosis and 279 women without endometriosis.', 'Surgical examination of the abdomino-pelvic cavity.', 'Preoperative serum CA-125 antigen levels were evaluated by electrochemoluminescence immunoassay in women with endometriosis and controls. Correlations between serum CA-125 levels and clinical and anatomical characteristics of disease severity were examined. Women with endometriosis displayed higher mean serum CA-125 levels compared with disease-free controls (50.162.4 U/mL vs 22.525.2 U/mL; p.001). CA-125 levels were significantly increased in women with OMA (60.863.5 U/mL) and DIE (55.268.7 U/mL) compared with women with SUP (23.224.5 U/mL) and controls (22.525.2 U/mL). There was no difference in CA-125 levels between patients with SUP and controls and between patients with OMA and DIE. CA-125 serum levels were correlated with DIE severity: the mean number of DIE lesions and worst DIE lesion.
Is increased serum cancer antigen-125 a marker for severity of deep endometriosis?

The human endometrium is an important site for contact between the host and pathogens ascending the reproductive tract, and thus plays an important role in female reproductive tract immunity. Previous work in our laboratory has suggested that Toll-like receptors (TLRs) are involved in endometrial epithelial recognition of pathogens and that ligation of endometrial TLRs results in the production of cytokines and chemokines important for both immune and reproductive functions of the endometrium. We have also demonstrated cyclic regulation of TLR3 mRNA and protein expression in human endometrium, suggesting that steroid hormones might play a role in the expression and function of TLR3. In this study, the effects of 17beta-estradiol (E2) and progesterone (P) on TLR3 expression and function in endometrial cell lines were investigated.', 'Endometrial epithelial cell lines were cultured and examined for the presence of TLR3 and hormone receptors by endpoint RT-PCR. For hormonal studies, cells were pre-treated with ethanol vehicle, 10(-8) M E2, and/or 10(-7) M P. For antagonist assays, cells were treated with the ER antagonist, ICI 182, 780, or the PR antagonist, RU486, for two hours prior to treatment with hormones. Following hormone or hormone/antagonist pre-treatment, cells were stimulated with vehicle, the synthetic TLR3 ligand, polyinosinic-polycytidylic acid (Poly I:C), a negative dsDNA control, or a positive control. Cytokine and chemokine production post-stimulation was measured by ELISA. The effects of E2 and P on TLR3 mRNA and protein expression were measured using Real Time RT-PCR and FACS analysis, respectively.', 'Stimulation of TLR3-expressing cells with the synthetic TLR3 ligand, Poly I:C, resulted in the production of cytokines and chemokines important for endometrial function and regulation. Suppression of Poly I:C-induced cytokine and chemokine production by cells treated with 10(-8) M E2, but not cells treated with 10(-7) M P, was observed in endometrial epithelial cell lines expressing TLR3 and estrogen receptor alpha (ERalpha). The effects of E2 were not observed on cells which did not express ERalpha or in cells pre-treated with the ER antagonist, ICI 182, 780. Treatment with E2 did not affect TLR3 mRNA or protein expression. However, treatment with E2 did suppress cytokine and chemokine production resulting from TLR3 stimulation with Poly I:C, suggesting that E2 modulates TLR3 function.
Does 17Beta-estradiol suppress TLR3-induced cytokine and chemokine production in endometrial epithelial cells?

The isoflavone puerarin [7-hydroxy-3-(4-hydroxyphenyl)-1-benzopyran-4-one 8-(-D-glucopyranoside)] possesses many biological activities. In this study, we investigated the effects of puerarin on adhesion molecules (AMs), including serum levels of intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and endothelial leukocyte adhesion molecule-1 (E-selectin), and the activation of nuclear factor kappa B (NF-B) in rabbits with experimental atherosclerosis.', 'In total, 24 rabbits were divided into control (standard diet), high-lipid diet (HLD), and PUE (HLD supplemented with puerarin) groups. At the end of weeks 0, 8, and 16, serum levels of AMs were measured. At the end of week 16, the thickness of the intima was detected. Protein and mRNA levels of AMs were checked by immunohistochemistry and RT-PCR, respectively. Protein levels of p65 NF-B and phosphorylation of inhibitor-B (I-B) were investigated by Western blotting.', 'Atherosclerotic lesions in the thoracic arch were found in the HLD and PUE groups, but not in the control group. Compared with the HLD group, the thickness of the intima in the PUE group was reduced. Our results indicate that puerarin reduced the protein and mRNA levels of AMs in this rabbit model. We also found that the reduced AM levels were due to inhibition of the phosphorylation and degradation of I-B, resulting in reduced p65 NF-B nuclear translocation.
Does puerarin inhibit the inflammatory response in atherosclerosis via modulation of the NF-B pathway in a rabbit model?
