Adenomyosis (ADS) is a common gynecological disorder, and its pathogenesis remains unclear. This study explores the functions of circRNAs in the eutopic endometrium of ADS and their diagnostic efficacy for ADS. High-throughput RNA sequencing was performed on 12 eutopic endometrial samples from ADS patients and 3 control endometrial samples. Additionally, circRNAs were analyzed in conjunction with clinical features. A competitive endogenous RNA network was established based on bioinformatics analysis, comprising 3 circRNAs, 1 miRNA, and 13 mRNAs. In the ADS group, the expression levels of hsa_circ_0008959 and SLC15A4 were significantly reduced, while hsa-miR-124-3p expression was increased. SLC15A4 was associated with cell proliferation and invasion. Decreased expression of hsa_circ_0008959 and SLC15A4, along with high VAS scores and elevated hsa-miR-124-3p levels, were identified as risk factors for ADS development. The combination of hsa_circ_0008959 and VAS scores demonstrated the highest diagnostic value for ADS.

Objective: Exosomes are secreted by most cell types and reflect the internal state of their cells of origin, playing crucial roles in the progression of various pathological conditions. Endometriosis is a chronic, estrogen-dependent inflammatory disease characterized by the ectopic presence of endometrial-like tissue outside the uterus, including in the ovaries, fallopian tubes, and peritoneal cavity. It primarily affects women of reproductive age and is often associated with infertility.

Adenomyosis and endometriosis, two common estrogen-dependent benign gynecological disorders usually present with overlapping symptoms, such as pain and infertility. These two conditions often co-exist and are associated with poor reproductive outcome. Both adenomyosis and endometriosis are associated with extracellular matrix (ECM) remodeling, regulated by matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs).

This systematic review aimed to summarize all available data and evaluate the roles of E-cadherin, N-cadherin, associated molecules, and signaling pathways in the pathogenesis of endometriosis. The search was conducted on PubMed, Cochrane Library, ClinicalTrials.gov, Scopus, Embase, and Google Scholar electronic databases.

Background: This study reveals elevated levels of MMP-1, MMP-2, and MMP-3 in endometriotic lesions, potentially reflecting a senescenceassociated secretory phenotype. No corresponding increase was observed in peritoneal fluid, possibly due to technical or sample-related limitations. These findings support the potential of MMPs as biomarkers and therapeutic targets in endometriosis.

Endometriosis is a disorder characterized by the presence of endometrial tissue outside the uterus, leading to dyspareunia, chronic pelvic pain, dysuria, and infertility. The latter has been related to implantation failure associated with alterations in decidualization, a process regulated by sex hormones such as progesterone. Membrane progesterone receptor β (mPRβ) exhibits a lower expression in endometriotic tissues than in normal endometrial ones.
