AI Article Synopsis

  • Endometriosis is a common condition that can really affect women's health, and researchers are studying if certain gene changes (called SNPs) in a gene called WTAP might increase the risk of getting it.
  • They looked at the genetic information of 473 women with ovarian endometriosis and 459 without it and found that some specific WTAP gene variations could raise or lower the chances of having the condition.
  • The study showed that people with two specific WTAP gene variations had a much higher risk of ovarian endometriosis compared to those without these variations, and the results were confirmed through different tests.

Article Abstract

Endometriosis is a common chronic gynecologic disorder with a significant negative impact on women's health. Wilms tumor 1-associated protein (WTAP) is a vital component of the RNA methyltransferase complex for N-methyladenosine modification and plays a critical role in various human diseases. However, whether single nucleotide polymorphisms (SNPs) of the WTAP gene predispose to endometriosis risk remains to be investigated. We genotyped three WTAP polymorphisms in 473 ovarian endometriosis patients and 459 control participants using the Agena Bioscience MassArray iPLEX platform. The logistic regression models were utilized to assess the associations between WTAP SNPs and the risk of ovarian endometriosis. In the single-locus analyses, we found that the rs1853259 G variant genotypes significantly increased, while the rs7766006 T variant genotypes significantly decreased the association with ovarian endometriosis risk. Combined analysis indicated that individuals with two unfavorable genotypes showed significantly higher ovarian endometriosis risk (adjusted OR = 1.71 [1.23-2.37], = 0.001) than those with zero risk genotypes. In the stratified analysis, the risk effect of the rs1853259 AG/GG and rs7766006 GG genotypes was evident in subgroups of age ≤30, gravidity≤1, parity≤1, rASRM stage I, and the rs7766006 GG genotype was associated with worse risk (adjusted OR = 1.64 [1.08-2.48], = 0.021) in the patients with rASRM stage II + III + IV. The haplotype analysis indicated that individuals with GGG haplotypes had a higher risk of ovarian endometriosis than wild-type AGG haplotype carriers. Moreover, false positive report probability and Bayesian false discovery probability analysis validated the reliability of the significant results. The quantitative expression trait loci analysis revealed that rs1853259 and rs7766006 were correlated with the expression levels of WTAP. Our findings demonstrated that WTAP polymorphisms were associated with susceptibility to ovarian endometriosis among Chinese women.

Background: Endometriosis is a complicated and enigmatic disease that significantly diminishes the quality of life for women affected by this condition. Increased levels of human telomerase reverse transcriptase () mRNA and telomerase activity have been found in the endometrium of these patients. However, the precise function of TERT in endometriosis and the associated biological mechanisms remain poorly understood.

Over the last decades, human infertility has become a major concern in public health, with severe societal and health consequences. Growing evidence shows that endocrine disruptors chemicals (EDCs) have been considered as risk factors of infertility. Their presence in our everyday life has become ubiquitous because of their universal use in food and beverage containers, personal care products, cosmetics, phytosanitary products.

Ovarian squamous cell carcinoma (SCC) is a rare entity among primary ovarian cancers. This type of cancer typically originates from the transformation of mature cystic teratomas, commonly known as dermoid cysts, and occasionally from associations with endometriosis or Brenner's tumors. The typical clinical scenario involves presentation in postmenopausal women, with symptoms arising from tumor growth or metastasis.

We evaluated the impact of adenomyosis and ovarian endometriosis on ovarian reserve function through transvaginal three-dimensional ultrasound and anti-mullerian hormone testing. A total of 150 female patients who were admitted to our hospital from January 2023 to May 2024 were selected; 58 cases had adenomyosis (adenomyosis group), 36 had ovarian endometriosis (ovarian endometriosis group), and 56 were healthy (healthy group). There were no statistically significant differences in clinical baseline data among the three groups (all P > 0.
