Ferroptosis, an iron-dependent form of regulated cell death driven by lipid peroxidation, is closely associated with mitochondrial damage, diminished glutathione peroxidase 4 activity, dysfunction of the System Xc- cystine/glutamate antipor…

Pain, an unpleasant but essential feeling for life, affects more than 20% of the global population and burdens health and the economy. Due to the lack of understanding of the exact fundamental mechanism, the existing therapeutic strategies …

BACKGROUND: Endometriosis (EM) is a chronic gynecological disorder that affects 5% to 10% of women of childbearing age, often causing pelvic pain and infertility. Fibrosis is a hallmark of EM progression, yet its underlying molecular driver…

BACKGROUND: Persistent low-grade inflammation has been hypothesized as a possible key contributor to polycystic ovary syndrome pathophysiology through associative studies. Since immune cells within the ovarian follicle-the central site of P…

BACKGROUND: Early diagnosis and treatment of endometriosis (EM) remain challenging because of the lack of knowledge about EM development. While oxidative stress (OS) has been associated with EM, the link is unclear. We explored OS-related g…

BACKGROUND: The etiology of interstitial cystitis/painful bladder syndrome (IC/BPS) remains elusive, presenting significant challenges in both diagnosis and treatment. To address these challenges, we employed a comprehensive approach aimed …

BACKGROUND: Ferroptosis and cuproptosis are closely associated with hepatic ischemia-reperfusion injury (HIRI). However, the significance of metabolic cell death-related genes (MRGs) in HIRI still awaits exploration. This study examined the…

PROBLEM: Unbalanced production of pro- and anti-inflammatory cytokines by immune cells is a hallmark of endometriosis. IL-24, a member of the IL-10 family, is a pleiotropic cytokine produced by both non-immune cells like astrocytes, keratin…

Interleukin-33 (IL-33) is a nuclear factor and member of the IL-1 cytokine family. IL-33 is mainly expressed by epithelial and endothelial cells and exerts its function through interaction with various immune cells, and binding to its recep…

BACKGROUND: Heart failure (HF) represents the terminal stage of various cardiovascular disorders, with immunogenic cell death (ICD) potentially influencing HF progression through modulation of immune cell activity. This study aimed to ident…

Chronic endometritis (CE) is a persistent inflammatory disorder of the endometrium, associated with infertility, recurrent pregnancy loss, and implantation failure. Diagnosis primarily depends on hysteroscopy and immunohistochemistry, while…

BACKGROUND: Ovarian cancer (OV) is the deadliest gynecologic malignancy owing to its late diagnosis and high metastatic propensity. Current biomarkers lack sufficient sensitivity and specificity for the detection of early-stage cancer. To a…

BACKGROUND: Chronic endometritis (CE) has been widely recognized as a potential cause of infertility, however, access to effective treatment is a formidable challenge due to the rudimentary understanding of the pathogenesis of persistent CE…

INTRODUCTION: Cisplatin resistance is a major challenge in ovarian cancer therapy, particularly for high-grade serous ovarian cancer (HGSOC). DNA topoisomerase IIα (TOP2A) relates to cancer drug resistance, yet its role and molecular mechan…

Endometriosis (EMS) is an oestrogen-dependent condition characterised by ectopic endometrial-like tissue growth with a chronic and inflammatory nature leading to severe symptoms and reduced quality of life. Emerging evidence implicates gut …

Macrophages are vital sentinels in innate immunity, and their functions cannot be performed without internal metabolic reprogramming. Mitochondrial dynamics, especially mitochondrial fusion and fission, contributes to the maintenance of mit…

The incidence and mortality rates of liver cancer in China remain elevated. Although early-stage liver cancer is amenable to surgical resection, a significant proportion of patients are diagnosed at advanced stages. Currently, in addition t…

Chronic pain is a defining feature of endometriosis and contributes significantly to the diminished quality of life observed in affected individuals. Despite advances in understanding disease pathology, current therapeutic strategies largel…

OBJECTIVE: Effective early diagnosis and timely intervention in acute pancreatitis (AP) are essential for improving patient outcomes. This study aims to evaluate the clinical utility of the neutrophil CD64 index (nCD64) in stratifying patie…

Neutrophil extracellular traps (NETs) are physiologically released in response to pathogens, serving as a defense mechanism. However, excessive NET production has been implicated in various pathological conditions, including diseases of the…

The postponement of childbearing age has become a global issue. Factors such as increased work pressures on women and environmental changes have led to a rising incidence and younger onset of premature ovarian insufficiency (POI). POI not o…

OBJECTIVE: This study aimed to assess whether anti-β2-glycoprotein I (β2GPI)/human leukocyte antigen (HLA)-DR autoantibodies are associated with pregnancy outcomes in women with infertility receiving assisted reproductive technology (ART) i…

Primary antiphospholipid syndrome (APS) is an autoimmune thrombophilic disorder characterized by recurrent venous or arterial thrombosis and/or pregnancy morbidity in the presence of persistent antiphospholipid antibodies (aPL). Renal invol…

BACKGROUND: The crosstalk between macrophages and trophoblasts plays a crucial role in the development and progression of recurrent spontaneous abortion (RSA). Although M1 macrophages (M1-Mφ) are known to accumulate in RSA decidual tissues,…

Interleukin (IL)-16 is expressed mostly by the cells of the human immune system. Upon cell activation IL-16 is cleaved, forming two functional proteins, one regulating cell cycle and the other acting as chemoattractant for the cells carryin…
