BACKGROUND: Epithelial ovarian carcinoma (EOC) comprises five main histological subtypes: high-grade serous (HGSOC), low-grade serous (LGSOC), clear cell (CCOC), mucinous (MOC), and endometrioid (ENOC). Each histotype harbors specific genom…

INTRODUCTION: Many women with endometriosis turn to digital sources for information. Meanwhile, large language models (LLMs) appear capable of offering health advice. This study aimed to evaluate the potential in answering endometriosis-rel…

G protein-coupled estrogen receptor (GPER) has been found to be an important key regulator in the homeostasis of sex hormone-dependent human cells. The aim of this study was to compare the expression of GPER, estrogen receptor alpha (ER-α),…

INTRODUCTION: Endometriosis is an inflammatory condition, affecting mainly women of reproductive age. Leptin is a regulator of food intake and energy expenditure, posing pleiotropic actions, and regulating immunity and fertility. The aim of…

BACKGROUND: Endometriosis, the presence of endometrial-like tissue outside the uterus, is a common clinical entity between women of reproductive age, with a prevalence of about 10%. Due to the variety of endometriosis-associated symptoms, a…

BACKGROUND: Endometriosis is one of the most common benign gynecological diseases with an occurrence approximately 10% in reproductive age. Endometriosis has been proposed as a possible precursor of certain ovarian carcinomas such as clear …

Endometriosis is a benign gynecologic condition affecting up to one woman out of ten of reproductive age. It is defined by the presence of endometrial-like tissue in localizations outside of the uterine cavity. It often causes symptoms such…

BACKGROUND: Endometriosis is one of the most common gynecological diseases of reproductive age, with a prevalence of 5-10% and grave consequences for quality of life and fertility. Vitamin D (vit D), a classic regulator of plasma calcium co…

BACKGROUND: Matrix metalloproteinases (MMPs), especially the gelatinases MMP-2 and MMP-9, play a crucial role in the pathogenesis of endometriosis by enabling invasion. Doxycycline is a well-tolerated antibiotic and a potent MMP-inhibitor i…

PURPOSE: Comparison of preoperative magnetic resonance imaging (MRI) with intraoperative findings in patients with deep infiltrating endometriosis (DIE) by means of the ENZIAN score. METHODS: This retrospective two-center study includes 63…

Endometriosis, a painful disorder associated with infertility, is estimated to occur in approximately 7-10% of reproductive age women. Although endometriosis is considered as an estrogen-dependent disease, the role of estrogen metabolites v…

OBJECTIVE: To investigate whether histone deacetylase inhibitors reduce the expression of the G-protein-coupled estrogen receptor (GPER) and whether the functional inhibition of GPER by the antagonist G-15 decreases the proliferation of end…

Class I histone deacetylases (HDACs-1-3) play an important role in steroid hormone-dependent gene expression and in modulating cell survival and proliferation. We analyzed their expression in a tissue microarray including 74 endometriosis s…

BACKGROUND: The G protein-coupled estrogen receptor (GPER) is thought to be involved in non-genomic estrogen responses as well as processes such as cell proliferation and migration. In this study, we analyzed GPER expression patterns from e…

Mutations of the tumor-suppressor gene ARID1A result in the loss of protein expression of the BRG-associated factor 250a (BAF250a), a large subunit of transcription-regulating Human SWI/SNF complexes, which have an important role in the con…

Endometriose, definiert als das Vorhandensein und Proliferieren von endometriumartigem Gewebe ausserhalb des Cavum uteri, ist eine häufige Ursache für chronische Unterbauchschmerzen, Dysmenorrhö und Sterilität. Insbesondere die medikamentös…

Endometriose, definiert als das Vorhandensein und Proliferieren von endometriumartigem Gewebe ausserhalb des Cavum uteri, ist eine häufige Ursache für chronische Unterbauchschmerzen, Dys menorrhö und Sterilität. Insbesondere die medikamentö…

Endometriose ist eine facettenreiche Erkrankung an der weltweit ungefähr 176 Mio. Frauen leiden. Die Erkrankung definiert sich durch das Vorhandensein und Proliferieren von endometriumartigem Gewebe ausserhalb Cavum uteri, wobei die Ätiopat…

OBJECTIVE: To investigate whether the histone deacetylase (HDAC) inhibitor romidepsin down-regulates VEGF (vascular endothelial growth factor) gene expression and abrogates VEGF protein secretion in human epithelial endometriotic cells. DE…
