Integrative Single-Cell Analysis Reveals Iron Overload-Induced Senescence and Metabolic Reprogramming in Ovarian Endometriosis-Associated Infertility.

Endometriosis, particularly ovarian endometriosis (OE), is a major cause of infertility, often associated with reduced oocyte quality and impaired ovarian function. Iron overload plays a key role in OE progression. This study investigates the effects of iron overload on follicular function in OE-associated infertility (OEI).

Immunomodulatory role of RNA modifications in sex hormone-dependent cancers.

Recent studies have identified that RNA epigenetic modifications, including m6A, m1A, m5C, etc, play pivotal roles in tumor progression. These modifications influence mRNA stability, RNA processing, translational efficiency, and decoding precision. However, comprehensive reviews detailing the connection between m6A RNA modifications and hormone-dependent cancers in both male and female populations remain scarce(breast cancer, ovarian cancer, and endometrial cancer, prostate cancer).

Melittin Inhibits Ovarian Cancer Cell Growth by Downregulating MMP9 Expression via the JAK2-STAT3 Signaling Pathway.

Curcumin suppresses malignant behaviors of ovarian cancer through regulation of tumor-associated macrophages.

Curcumin, a natural polyphenol with established anti-tumor properties, has shown therapeutic potential in ovarian cancer. However, its mechanisms, particularly through modulation of tumor-associated macrophages (TAMs) in the tumor microenvironment, remain unexplored. This study aimed to elucidate how curcumin suppresses ovarian cancer progression by regulating TAM polarization.

N6-methyladenosine methylation regulators can serve as potential biomarkers for endometriosis related infertility.

Endometriosis (EMS) is a chronic inflammatory disease frequently associated with infertility. N6-methyladenosine (m6A) methylation, the most common form of methylation in eukaryotic mRNAs, has gained attention in the study of female reproductive diseases, including EMS and infertility. This study aimed to investigate the role of m6A regulators in EMS-related infertility.

Chronic unpredictable stress induces anxiety-like behavior and oxidative stress, leading to diminished ovarian reserve.

Chronic stress can adversely affect the female reproductive endocrine system, potentially leading to disorders and impairments in ovarian function. However, current research lacks comprehensive understanding regarding the biochemical characteristics and underlying mechanisms of ovarian damage induced by chronic stress. We established a stable chronic unpredictable stress (CUS)-induced diminished ovarian reserve (DOR) animal model.

Gut Microbiota Disorder Contributes to the Production of IL-17A That Exerts Chemotaxis via Binding to IL-17RA in Endometriosis.

Introduction: Endometriosis (EM) is a chronic estrogen-dependent condition characterized by the growth of endometrial-like tissue outside the uterus, posing a significant burden on reproductive-aged women. Previous research has shown a correlation between gut microbiota dysbiosis and interleukin-17A (IL-17A) in EM patients. IL-17A, a promising immunomodulatory molecule, exerts dual roles in human physiology, driving inflammatory diseases.

Effect of baseline prolactin levels on the pregnancy outcomes after fresh embryo transfer.

Background And Aims: There is clinical disagreement on whether to treat hyperprolactinemia with medication before embryo transfer. The aim of this study is to identify the impact of basal prolactin (PRL) levels on pregnancy outcomes in fresh embryo transfer cycles.

Methods: This retrospective study involved 2,648 women who underwent basal PRL level testing and fresh embryo transfer between January 2015 and December 2020 at our Hospital's Department of Assisted Reproduction.

Therapeutic effects of Huayu Jiedu formula on endometriosis via downregulating GATA 6 expression.

Background: Endometriosis (EMs) is a common chronic inflammatory disease which is characterized by multiple clinical symptoms and high recurrence rate due to the absence of effective therapies. Huayu Jiedu Formula (HYJDF), is a traditional Chinese medicine prescription with five major herbs. It has been used as traditional medicine to treat EMs for more than twenty years and exerted a good therapeutic effect.

Double-edged roles of ferroptosis in endometriosis and endometriosis-related infertility.

Endometriosis is strongly associated with infertility. Several mechanisms have been reported in an attempt to elucidate the pathophysiological effects that lead to reduced fertility in women with endometriosis. However, the mechanisms by which endometriosis affects fertility have not been fully elucidated.

Past and present: a bibliometric study on polycystic ovary syndrome.

Background: Polycystic ovary syndrome (PCOS) is a common gynecological endocrine disease that has a great impact on women's physical and mental health. It is a burden to social and patients' economy. In recent years, researchers' understanding of PCOS has reached a new level.

Characteristics and possible mechanisms of metabolic disorder in overweight women with polycystic ovary syndrome.

Background: Polycystic ovary syndrome (PCOS) is a kind of endocrine and metabolic disorder, disturbing the females of reproductive age. Here, we aimed to investigate the metabolic characteristics of overweight women with PCOS and analyze the possible mechanisms.

Methods: We conducted a cross-sectional study on 947 patients with PCOS, who were classified according to body mass index (BMI) as overweight (BMI ≥ 24 kg/m) or non-overweight (BMI ≤ 23.

Mechanism of Thunberg Fritillaria in treating endometriosis based on network pharmacology and the effect of Peiminine on the MEK/ERK pathway.

Objective: To explore the mechanism of Thunberg Fritillaria in treating endometriosis (EMs) based on network pharmacology and the effect of Peiminine on the MEK/ERK pathway.

Methods: We applied Chinese medicine system pharmacology analysis platform (TCMSP) database and literature search to screen the main chemical components of Fritillaria thunbergii Miq and created a Vanny map from the databases of TCMSP, GENECARDS, Online Mendelian Inheritance in Man (OMIM), and some others. The STRING database was used to construct the protein interaction network of Fritillaria thunbergii Miq and EMs.

Huayu Jiedu Fang Protects Ovarian Function in Mouse with Endometriosis Iron Overload by Inhibiting Ferroptosis.

Endometriosis (EM) is a common chronic inflammatory disease in women. Sampson's retrograde menstruation theory is the most widely accepted theory of EM pathogenesis. The periodic bleeding of ectopic lesions is an important pathological feature of this disease, and the occurrence and progression of EM are closely associated with the iron overload caused by ectopic lesions.

Influence of the gut microbiota on endometriosis: Potential role of chenodeoxycholic acid and its derivatives.

The gut microbiota (GM) has received extensive attention in recent years, and its key role in the establishment and maintenance of health and in the development of diseases has been confirmed. A strong correlation between the GM and the progression of endometriosis (EMS) has been observed in emerging research. Alterations in the composition and function of the GM have been described in many studies on EMS.

Iron-overloaded follicular fluid increases the risk of endometriosis-related infertility by triggering granulosa cell ferroptosis and oocyte dysmaturity.

Endometriosis (EMs) occurs in approximately 50% of women with infertility. The main causes of EMs-related infertility are follicle dysplasia and reduced oocyte quality. Iron overload occurs in ovarian follicular fluid (FF) of patients with EMs, and this condition is associated with oocyte maturation disorder.

Ferroptosis-Related Long Noncoding RNAs as Prognostic Biomarkers for Ovarian Cancer.

Ovarian cancer (OC) is a highly malignant gynecologic tumor with few treatments available and poor prognosis with the currently available diagnostic markers and interventions. More effective methods for diagnosis and treatment are urgently needed. Although the current evidence implicates ferroptosis in the development and therapeutic responses of various types of tumors, it is unclear to what extent ferroptosis affects OC.
