BACKGROUND: Emerging evidence suggests that aberrantly expressed microRNAs (miRNAs) participate in endometriosis pathogenesis. miR-1229-5p participates in the pathogenesis of several disease, but its precise role and mechanism in endometrio…

Endometriosis (EMs) is a common gynecological disease accompanied by metabolic disturbances. However, the causality between metabolites and the risk of EMs remains unclear. We conducted a 2-sample Mendelian randomization (MR) analysis using…

BACKGROUND: Ferroptosis, a recently discovered iron-dependent cell death, is linked to various diseases but its role in endometriosis is still not fully understood. METHODS: In this study, we integrated microarray data of endometriosis fro…

Growing evidence indicates that aberrant methylation is pivotal in the development and progression of endometriosis (EMs). This study explores the relationship between abnormal methylation of the ENPP3 promoter and the pathogenesis of ovari…

Abnormal gene expression caused by epigenetic changes, including DNA methylation, is associated with the development and progression of endometriosis. Grainyhead-like 2 gene (GRHL2), a suppressor of epithelial-mesenchymal transition, has be…

Background: The aim of this study was to confirm and analyze the correlative factors that could influence the recurrence of ovarian endometriosis after conservative surgery, including both risk and protective factors. Methods: From January …

BACKGROUND: The aim of the study was to investigate the role of the genetic variation of glutathione S-transferase M1 (GSTM1) in the development of ovarian endometriosis and endometriosis-related primary infertility risk. METHODS: This case…

Studies have shown that aberrant expression of IL-12p40, which is encoded by the interleukin-12B (IL-12B) gene, may be involved in the development of endometriosis. In this study, we investigated the role of aberrant methylation of the IL-1…

Endometriosis is a common chronic gynecologic disorder characterized by the presence and growth of endometrial-like tissue outside of the uterine cavity. Although the exact etiology remains unclear, epigenetic modifications, such as DNA met…

STUDY QUESTION: Is the methylation status of the glutathione S-transferase M1 (GSTM1) promoter region altered in patients with ovarian endometriosis, and does this affect the expression of GSTM1 in their endometrial tissues? SUMMARY ANSWER:…

Endometriosis is a common multifactorial disease caused by an interaction between multiple gene loci and environment. Four genome-wide association studies (GWASs) of endometriosis have identified several single-nucleotide polymorphisms (SNP…

The loss of E-cadherin expression plays an important role in the development of endometriosis, but the molecular mechanism is not clear to date. It has been confirmed that the hypermethylation of the CpG island may be an important molecular…

The first tumor metastasis-suppressor gene, nm23, may have an important role in the pathogenesis of endometriosis (EM). The present study aimed to evaluate whether nm23 gene polymorphisms are correlated with the risk of the development of E…

AIM: To investigate the association of tag single nucleotide polymorphisms (SNPs) in the vascular endothelial growth factor receptor 2 (VEGFR-2) gene with susceptibility to endometriosis. METHODS: This study comprised 571 patients with endo…

BACKGROUND: Angiogenesis appears to be an important event in the pathophysiology of endometriosis (EM) and adenomyosis. Two angiogenic factors, fibroblast growth factor (FGF) 1 and 2, play a central role in the initiation of angiogenesis. W…

BACKGROUND: Vascular endothelial growth factor (VEGF) plays an important role in the development of endometriosis. The aim of this study was to investigate the association of polymorphisms in the VEGF gene with the susceptibility to endomet…

OBJECTIVE: To investigate the association of single nucleotide polymorphisms (SNPs) in VEGF gene with the risk of endometriosis and adenomyosis. METHODS: Genotypes were analyzed by polymerase chain reaction-restriction fragment length polym…

Vascular endothelial growth factor (VEGF), a major mediator of angiogenesis and vascular permeability, may play a key role in the development of adenomyosis. The aim of this study was to investigate whether these four VEGF polymorphisms (-2…

The matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinases (TIMPs) may contribute to the development of adenomyosis. The aim of the present study was to investigate whether three single nucleotide polymorphisms (SNPs) i…

OBJECTIVE: To investigate the association of single nucleotide polymorphisms (SNPs) in matrix metalloproteinase-2 (MMP-2) and tissue inhibitor of metalloproteinase-2 (TIMP-2) with the risk of endometriosis and adenomyosis. METHODS: Genotype…
