    To study the association between urinary phthalate metabolite levels, endometriosis, and their effects on human granulosa cells, we recruited patients who underwent laparoscopy to confirm endometriosis (n = 123) and control patients (n = 78). Liquid chromatography-tandem mass spectrometry was used to measure the following five urinary phthalate metabolites: mono-n-butyl phthalate (MnBP), mono(2-ethylhexyl) phthalate, monobenzyl phthalate, mono(2-ethyl-5-oxo-hexyl) phthalate, and mono(2-ethyl-5-hydroxyhexyl) phthalate. Urinary MnBP levels were higher in patients with endometriosis than in controls after multivariable logistic regression including the number of deliveries, body mass index, and use of medicine as covariables. MnBP correlates with other phthalate metabolites. Previous studies found that endometriosis was a detrimental condition for granulosa cells. In our study, we observed whether MnBP affected granulosa cells. MnBP treatment altered the gene expression of BIRC5, BUB1B, CDC20, cyclin B1, IL-1 beta, TNF-alpha, inhibin-B, StAR, and P450ssc and attenuated the ratio of the mitochondrial membrane potential in human granulosa cells. Moreover, MnBP decreased the expression of the anti-Mullerian hormone. These findings suggest that MnBP concentration is associated with endometriosis and may affect the health and steroidogenesis of human granulosa cells.

    OBJECTIVE: To investigate whether vascular endothelial growth factor (VEGF) gene 5'-UTR-460 polymorphism could be used as a marker of susceptibility to endometriosis. STUDY DESIGN: Women were divided into 2 groups, endometriosis (n = 122) and nonendometriosis (n = 131). Polymorphisms for VEGF were detected by polymerase chain reaction and BstUI (New England Biolabs, Beverly, Massachusetts) restriction enzyme analysis. Genotypes and allelic frequencies between the groups were compared. RESULTS: Proportions of different VEGF polymorphisms in the groups were significantly different. Proportions of cuttable (C) homozygote/heterozygote/uncuttable (T) homozygote for VEGF in the groups were 0144.3155.7% and 0/63.4/36.6%, respectively. A higher percentage of T/T homozygote and T allele was present in the endometriosis population. The proportions of C/T alleles in the groups were 22.1/77.9% and 31.7/68.3%, respectively. CONCLUSION: T/T homozygotes and the T allele of the VEGF-460 gene are associated with a higher risk of endometriosis. Heterozygotes and C allele are related to the lower risk of endometriosis formation. VEGF polymorphism likely contributes to the pathogenesis of endometriosis and may become a useful marker for predicting endometriosis susceptibility.

    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 enclometriosis and group 2 (n = 159) of women with no enclometriosis. The polymerase chain reaction (PCR) was used to identify the cuttable (C) and uncuttable (T) polymorphism of the CDH1-Pm/ l gene (rs1801026) located on the T-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 distributions of the CDH1-Pml/ l C/T polymorphism were significantly different in both groups. In group 1 the CDH1*C frequency was 47.7% and the T frequency 52.3%, while the CC homozygote frequency was 6.7%, the TT homozygote 11.3% and the CT heterozygote 82%. In group 2 the CDH1*C frequency was 17% and the T frequency 83%, while the CC frequency was 0.6%, the TT 66.1% and the CT 33.3%. These data indicate that the CDH1 gene polymorphism may be associated with the development of severe endometriosis and that the CDH1 gene C allele is related to higher susceptibility to enclometriosis.
