It comprises multiple histological subtypes, among which pancreatic ductal adenocarcinoma (PDAC) represents the most prevalent exocrine neoplasm and accounts for the vast majority of all pancreatic cancer cases. Perineural invasion (PNI) stands as one of the defining biological hallmarks of PDAC. Detected in 80%-100% of PDAC patients, PNI serves as an independent adverse prognostic factor that drives local recurrence, distant metastasis, and resistance to both chemotherapy and immunotherapy. Historically regarded as a passive route for tumor dissemination, PNI is now recognized as a complex, multicellular process involving bidirectional crosstalk between cancer cells, nerve fibers, stromal cells, and immune components within the tumor microenvironment. This review dissects the molecular mechanisms underlying neuro-tumor interactions and proposes a unified four-stage mechanistic model of PNI, encompassing mutual chemotaxis between tumors and nerves, adhesion and invasion at the tumor-nerve interface, extracellular matrix remodeling, and neural plasticity alterations. Notably, we define the perineural invasion microenvironment as a neuro-immune privileged sanctuary, and delineate its multicellular composition and pathological consequences based on current research advances. Furthermore, we summarize potential therapeutic strategies targeting the neuro-immune-tumor axis and ongoing clinical trials, discuss key translational challenges, and highlight the transformative applications of multi-omics technologies and artificial intelligence in PNI diagnosis, mechanistic discovery, and therapeutic optimization.

NPC arises from a complex interaction among persistent Epstein-Barr virus (EBV) infection, inherited susceptibility, and environmental exposures. Among these factors, EBV plays a central role in endemic NPC through latent gene products, particularly latent membrane protein 1 (LMP1), latent membrane protein 2A (LMP2A), and Epstein-Barr nuclear antigen 1 (EBNA1), which sustain oncogenic signaling, remodel the tumor microenvironment, and reinforce malignant progression. Clinically, NPC is often diagnosed at a locoregionally advanced stage because of its deep anatomical location and nonspecific early symptoms, making accurate detection, risk stratification, and treatment selection particularly important. Although previous reviews have addressed individual aspects of NPC biology or management, an integrated framework linking epidemiological determinants, viral oncogenesis, host molecular dysregulation, and therapeutic evolution remains needed. This review therefore synthesizes current evidence on NPC epidemiology, risk factors, EBV-associated molecular mechanisms, major signaling pathways and their crosstalk, genetic and epigenetic alterations, clinical features, diagnosis, staging, and management. Particular emphasis is placed on the clinical roles and limitations of plasma EBV DNA, the distinction between established standards and investigational strategies, and emerging molecular and immune-based therapies.

Candidate genes were first identified by pharmacologic demethylation combined with RNA sequencing across OSCC cell lines, then validated by quantitative RT-PCR, methylation-specific PCR, and bisulfite sequencing in OSCC cell lines, normal oral mucosa, and primary OSCC tumors, with independent confirmation in the TCGA-HNSC dataset.

Validation in oral cavity tumor samples extracted from the TCGA-HNSC dataset confirmed tumor-specific hypermethylation and revealed significant inverse correlations between methylation and expression for GPX3, GPRC5B, and CTGF.

Cardiac fibroblasts and myofibroblasts serve as the principal effector cells responsible for matrix accumulation, whereas cardiomyocytes and immune cells contribute to fibrotic expansion through inflammatory signaling, paracrine communication, and microenvironmental regulation. Transforming growth factor-β, the renin-angiotensin-aldosterone system, inflammatory cytokines, mechanical stress, and metabolic disturbances collectively orchestrate a profibrotic signaling network.

This study provides evidence that betaine (trimethylglycine; BET) can regulate the Keap1-Nrf2 axis through modulation of Keap1. In biochemical and cellular assays, betaine was associated with methylation of Keap1 at Cys513 and Cys518 within the Kelch domain, which was linked to enhanced p62-dependent autophagic degradation of Keap1 and Nrf2 stabilization. In AML12 hepatocytes and in mice, betaine enhanced Nrf2 activity, induced canonical Nrf2 target genes, and increased cellular glutathione (GSH), consistent with improved GSH-dependent redox capacity. In an acetaminophen (AAP) overdose model, betaine attenuated hepatic injury, consistent with improved redox capacity under acute toxic stress. In an MCD diet-induced steatotic liver disease model, betaine was associated with reduced steatohepatitis-like histopathology, inflammatory signaling, and lipogenic markers. Finally, RNA-seq analysis of a large human metabolic dysfunction-associated steatotic liver disease (MASLD) cohort revealed Nrf2-related transcriptomic signatures associated with disease severity, providing correlative support for the disease relevance of this pathway.
