Epithelial cadherin (E-cadherin; CDH1) may influence pericellular proteolysis and intracellular signal transduction, which plays an essential part of tumor invasion. In our study we investigated the correlation between CDH1 gene polymorphism and endometriosis in two groups of pre-menopausal Taiwanese women, group 1 (n = 150) consisting of women with severe stage IV endometriosis and group 2 (n = 159) of women with no endometriosis. The polymerase chain reaction (PCR) was used to identify the cuttable (C) and uncuttable (T) polymorphism of the CDH1-Pml I gene (rs1801026) located on the 3’-untranslated region (3’-UTR) of chromosome 16 and compare the genotypes and allelic frequencies of this gene in both groups. We found that the genotype and allele...

Insulin-like growth factor II (IGF2) has been shown to play a role in abnormal cell growth and carcinogenesis. We investigated if the IGF2 gene Apa I polymorphism at exon 9 was associated with the susceptibility to endometriosis, analyzing 120 women with moderate/severe endometriosis and 103 controls. The genotype frequencies did not differ statistically between the endometriosis (aa = 25.4, ab = 57.4, bb = 17.2%) and control (aa = 20.8 ab = 52.8, bb = 26.4%) groups. The allele frequencies did not differ either: a = 54.1, b = 45.9% among women with endometriosis and a = 47.2, b = 52.8% in the control group. Therefore, no indication was found for an association of this polymorphism with endometriosis susceptibility.

Endometriosis is an estrogen-dependent disease in reproductive age women. Adiponectin and Nitric oxide (NO) have an important role in physiologic functions especially in human reproductive system. Levels of NO increased in the endometriosis patients but serum adiponectin levels decreased in woman with endometriosis. The aim of this study was to determine adiponectin effect on nitric oxide secretion by cultured normal and endometriotic human endometrial stromal cells. In this experimental study, normal (n= 10) and endometriotic endometrial biopsies (n= 10) were taken in sterile condition. Stromal cells isolated and cultured in in DMEM/ F12 medium and treated with adiponectin concentrations (0, 10, 100, and 200 ng/ml) for 24 and 48 hours. NO assay was done...

Endometriosis is a complex and multifactorial disease. Chromosomal imbalance screening in endometriotic tissue can be used to detect hot-spot regions in the search for a possible genetic marker for endometriosis. The objective of the present study was to detect chromosomal imbalances by comparative genomic hybridization (CGH) in ectopic tissue samples from ovarian endometriomas and eutopic tissue from the same patients. We evaluated 10 ovarian endometriotic tissues and 10 eutopic endometrial tissues by metaphase CGH. CGH was prepared with normal and test DNA enzymatically digested, ligated to adaptors and amplified by PCR. A second PCR was performed for DNA labeling. Equal amounts of both normal and test-labeled DNA were hybridized in human normal...

Provedor de dados: 56
Autores: Glitz,C.; Souza,C.A.; Rodini,G.P.; Genro,V.; Bilibio,J.P.; Senger,M.; Cunha-Filho,J.S.
Interleukin-18 (IL-18) is a cytokine that belongs to the IL-1 family. Endometriosis is strongly associated with sub-fertility, and affects about 15% of women of reproductive age. IL-18 may favor the progression of endometriosis. The objective of the present study was to determine the concentration of IL-18 in the serum and peritoneal fluid of infertile women with endometriosis. Forty infertile and 25 fertile women were screened in a teaching hospital. Thirty-four infertile patients with minimal or mild endometriosis and 22 fertile controls were enrolled in the study. The primary outcome was the estimate of IL-18 levels and the secondary outcome was the correlation between serum and peritoneal levels of IL-18. There were no differences between the two...

Peritoneal fluid modulates the sperm acrosomal exocytosis induced by N-acetylglucosaminyl neoglycoprotein
Provedor de dados: 56
Autores: Passos,E.P.; Brugnara,L.; Facin,A.C.; Riffel,A.; Lima,G.R.; Freitas,V.; Brandelli,A.
The effect of peritoneal fluid (PF) on the human sperm acrosome reaction (AR) was tested. Sperm was pre-incubated with PF and the AR was induced by calcium ionophore A23187 and a neoglycoprotein bearing N-acetylglycosamine residues (NGP). The AR induced by calcium ionophore was inhibited 40% by PF from controls (PFc) and 50% by PF from the endometriosis (PFe) group, but not by PF from infertile patients without endometriosis (PFi). No significant differences were found in the spontaneous AR. When the AR was induced by NGP, pre-incubation with PFc reduced (60%) the percentage of AR, while PFe and PFi caused no significant differences. The average rates of acrosome reactions obtained in control, NGP- and ionophore-treated sperm showed that NGP-induced...

Provedor de dados: 56
Autores: Rocha,M.G.; Gomes,V.A.; Tanus-Santos,J.E.; Rosa-e-Silva,J.C.; Candido-dos-Reis,F.J.; Nogueira,A.A.; Poli-Neto,O.B.
The objective of this prospective study was to determine the plasma levels of nitric oxide (NO) in women with chronic pelvic pain secondary to endometriosis (n=24) and abdominal myofascial pain syndrome (n=16). NO levels were measured in plasma collected before and 1 month after treatment. Pretreatment NO levels (μM) were lower in healthy volunteers (47.0±12.7) than in women with myofascial pain (64.2±5.0, P=0.01) or endometriosis (99.5±12.9, P&lt;0.0001). After treatment, plasma NO levels were reduced only in the endometriosis group (99.5±12.9 vs 61.6±5.9, P=0.002). A correlation between reduction of pain intensity and reduction of NO level was observed in the endometriosis group [correlation = 0.67 (95%CI = 0.35 to 0.85), P&lt;0.0001]. Reduction of NO...

Autores: Lima,A.P.; Moura,M.D.; Rosa e Silva,A.A.M.
Endometriosis is a progressive estrogen-dependent disease affecting women during their reproductive years. The objective of the present study was to investigate whether endometriosis is associated with stress parameters. We determined cortisol and prolactin levels in serum, peritoneal and follicular fluid from infertile women with endometriosis and fertile women without the disease. The extent of the disease was staged according to the revised American Fertility Society classification (1997). Serum and peritoneal fluid were collected from 49 women aged 19 to 39 years undergoing laparoscopy. Eighteen women had stage I-II endometriosis and 10 had stage III-IV. Controls were 21 women undergoing laparoscopy for tubal sterilization. Follicular fluid was...

Provedor de dados: 56
Autores: Araujo,F.M.; Meola,J.; Rosa-e-Silva,J.C.; Paz,C.C.P.; Ferriani,R.A.; Nogueira,A.A.
Endometriosis is a benign, estrogen-dependent disease with symptoms such as pelvic pain and infertility, and it is characterized by the ectopic distribution of endometrial tissue. The expression of the ID2, PRELP and SMOC2 genes was compared between the endometrium of women without endometriosis in the proliferative phase of their menstrual cycle and the eutopic and ectopic endometrium of women with endometriosis in the proliferative phase. Paired tissue samples from 20 women were analyzed: 10 from endometrial and peritoneal endometriotic lesions and 10 from endometrial and ovarian endometriotic lesions. As controls, 16 endometrium samples were collected from women without endometriosis in the proliferative phase of menstrual cycle. Analysis was performed...
