Ferroptosis-related immune microenvironment and prognostic signature in high-grade endometrial carcinoma: integrated bulk and single-cell analysis

Abstract Background High-grade (FIGO Grade 3) uterine corpus endometrial carcinoma (UCEC) is an aggressive malignancy with limited therapeutic options and a poor prognosis. While ferroptosis is implicated in various cancers, its specific role within the tumor immune microenvironm...

Immune-pressure redistribution in resistance to PD-1/PD-L1 blockade: mechanisms, biomarkers, and therapeutic design

PD-1/PD-L1 blockade can produce durable tumor control, yet primary, adaptive, and acquired resistance remain common. Existing accounts often catalogue resistance by cellular compartment, obscuring the coordinated nature of tumor adaptation. Here, we introduce immune-pressure redi...

Potential of plasma metagenomic next-generation sequencing to guide antibiotic therapy in acute necrotizing pancreatitis with early fever: a prospective multicenter cohort study

Indiscriminate antibiotic use remains common in febrile patients with acute necrotizing pancreatitis (ANP), particularly during the early phase. Metagenomic next‑generation sequencing (mNGS) has shown diagnostic utility for infected pancreatic necrosis (IPN) and may offer a means...

Fibroblast growth factor 21 is linked to ambient temperature-dependent regulation of pathological cardiac hypertrophy in UCP1 knockout mice

Adipocytes play an important role in the regulation of cardiovascular health and disease. However, the molecular mechanisms underlying the endocrine role of brown adipose tissue (BAT) in pathological cardiac remodeling remain unclear. Herein, we show that uncoupling protein 1 (UC...

Mitochondrial Remodeling, Cytoskeletal Dynamics, and Translational Control During Drosophila Spermatid Elongation: An Integrative Review

Spermatogenesis in Drosophila melanogaster is a classical model for studying cell polarity establishment, organelle remodeling, and extreme cellular morphogenesis. Spermatid elongation involves a series of highly coordinated dynamic events, including nuclear polarization, axonema...

Development and validation of a two-gene urine DNA methylation assay for noninvasive prostate cancer detection: a prospective multicenter study

Prostate-specific antigen (PSA) screening lacks specificity, particularly within the 4-10 ng/mL diagnostic gray zone, leading to unnecessary prostate biopsies and overtreatment. Here, we developed and validated a streamlined urine DNA methylation assay for non-invasive prostate c...
