Breast cancer (BCA) is one of the most common cancers worldwide, with a high rate of mortality and morbidity in women. This review focuses on the applications of nanotechnology, nanomaterials, and nanoparticles (NPs) in BCA, encompassing diagnosis and therapy. Nanotechnologies, nanocarriers, and nano-encapsulations versus their corresponding counterparts for BCA diagnosis and therapy have been discussed. Various drug formulations into different nanocarriers (lipid NPs, nanoemulsions, polymeric NPs, and metal-based NPs) enhanced their bioavailability and therapeutic efficacy, overcoming the limitations of conventional formulations. Additionally, clinical specialists have achieved improved outcomes in the detection and monitoring of BCA at various stages using nanotechnology, ultimately leading to an improved quality of life for patients.

Given the lack of efficient biomarkers for hepatocellular carcinoma (HCC) diagnosis, this study aimed to develop an HCC diagnostic strategy based on serum protein glycosylation signatures. We characterized differential N-glycosylation patterns of serum IgG to differentiate HCC from healthy controls and liver cirrhosis, and elucidated the molecular mechanisms driving aberrant Neu5Gc elevation in HCC to provide a theoretical basis for clinical application and differential diagnosis of HCC.

LIP-ELISA was applied to quantify serum Neu5Gc in 6,768 healthy individuals for baseline establishment. IgG was purified and subsequently analyzed by RPLC-MS/MS for glycosylation profiling in HCC and healthy samples. Bioinformatic analysis of CMAH and related gene clusters modulating Neu5Gc synthesis was conducted.

In a cohort of 1,114 participants, the LIP-ELISA platform achieved 80.21% sensitivity, 96.01% specificity, and 92.46% accuracy for primary HCC diagnosis. Serum IgG from HCC patients displayed multi-branched N-glycans modified with core fucose and Neu5Gc. Key molecules involved in glycan modification were identified, enabling the development of multiplexed gene detection for HCC, LC, and chronic hepatitis B. In vitro assays confirmed hypoxia-induced sialic acid accumulation in HCC cells. Meanwhile, CMAH-knockout mouse experiments verified that an exogenous high-sialic-acid diet compensates for endogenous Neu5Gc synthesis deficiency, revealing a dietary-mediated compensatory mechanism for Neu5Gc elevation.

This study established an LIP-ELISA-based clinical diagnostic platform combining AFP and Neu5Gc, defined sialic acid–modified glycan structures, and preliminarily identified regulators of Neu5Gc biosynthesis, providing novel insights for HCC diagnosis and mechanism research.

The nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) family regulates fundamental processes in both innate and adaptive immunity. Aberrant NF-κB activation, whether through canonical or non-canonical signaling pathways, contributes to chronic inflammation, autoimmunity, allergy, and primary immunodeficiency/autoinflammatory syndromes, while also influencing host defense and tissue repair mechanisms. The present review aims to synthesize molecular architecture, upstream triggers, ubiquitin-centered relay systems, and the dynamic regulation of NF-κB activity. The major findings on the NF-κB signaling pathway encompass its dual molecular mechanisms (canonical and non-canonical), its central roles in immune and inflammatory responses, cell survival, and development, as well as its complex regulatory networks. We interpret NF-κB as a master integrator of diverse signals, essential for both acute and long-term physiological processes. Dysregulation of NF-κB underlies many diseases, and while it is a promising therapeutic target, its ubiquitous functions demand precise modulation to avoid adverse effects. In conclusion, the proper function of the NF-κB signaling pathway is essential for maintaining cellular homeostasis and immune defense; its dysregulation is linked to chronic inflammatory diseases, autoimmune disorders, and cancer, which underscores the pathway’s significance as a therapeutic target. Although it elucidates molecular processes and treatment options, experimental validation of emerging therapeutic concepts such as ubiquitin code editing and spatial immunology remains limited.

The optimal management strategy for adults with immune-tolerant (IT) chronic hepatitis B infection remains undefined. This study aimed to investigate the efficacy and predictive factors of a pegylated interferon (Peg-IFN)-based treatment strategy in IT patients with chronic HBV infection.

In this pilot, open-label, prospective study, 286 patients aged 18 to 60 years with IT characteristics were enrolled and allocated to one of three groups. The combination group received Peg-IFN for 48–96 weeks, with tenofovir disoproxil fumarate (TDF) initiated at week 12 and continued through week 96 (n = 103). The monotherapy group received TDF monotherapy alone (n = 125), and the control group was monitored without therapeutic intervention (n = 58).

No patients in the control group met any predefined efficacy endpoints. Intention-to-treat analysis showed that patients in the combination group achieved significantly higher virological response rates (71.8% vs. 53.6%, p = 0.005), hepatitis B e antigen seroconversion rates (15.5% vs. 1.6%, p < 0.001), and hepatitis B surface antigen (HBsAg) loss rates (10.7% vs. 0%, p < 0.001) compared with those in the monotherapy group at week 96. In the combination group, the cumulative rate of HBsAg loss was 5.4% at week 48 and increased to 11.8% by week 96. Independent predictors of achieving either hepatitis B e antigen seroconversion or HBsAg loss were baseline age under 30 years (odds ratio = 0.217, 95% confidence interval: 0.048–0.976, p = 0.046) and a decline in HBsAg level greater than 1 log10 IU/mL by week 24 (odds ratio = 13.976, 95% confidence interval: 2.506–77.932, p = 0.003).

A Peg-IFN-based treatment strategy significantly increases response rates compared with TDF monotherapy or observation in patients with IT characteristics.

N6-methyladenosine (m6A), the most prevalent internal RNA modification in eukaryotic cells, is a dynamic regulator of RNA metabolism and cancer biology. In colorectal cancer (CRC), dysregulated m6A reshapes transcriptomic programs that control tumor growth, metastasis, immune evasion, and therapeutic resistance. However, the context-dependent functions of individual m6A regulators remain incompletely defined, the integration of m6A with canonical oncogenic signaling remains incomplete, and its role in metabolic reprogramming lacks a systematic overview. This review aims to integrate current evidence on m6A regulatory machinery in CRC, clarify its coordination with oncogenic signaling and metabolic pathways, and highlight emerging translational implications. The key players regulating m6A in CRC progression are m6A “writers”, including methyltransferase-like 3 and methyltransferase-like 14; m6A “erasers”, including fat mass and obesity-associated protein and AlkB homolog 5; and m6A “readers”, including the YTH m6A RNA-binding protein family and the insulin-like growth factor 2 mRNA-binding protein family. m6A modification coordinates key oncogenic pathways, including Wnt/β-catenin, PI3K/Akt, MAPK, and p53 signaling. Moreover, m6A-dependent regulation of metabolic enzymes such as hexokinase 2, pyruvate kinase M2, and fatty acid synthase promotes the reprogramming of glucose, amino acid, and lipid metabolism, linking epitranscriptomic control to bioenergetic adaptation. We also discuss context-dependent and paradoxical functions of m6A regulators and advances in m6A-targeted therapies. In conclusion, m6A modification functions as a central regulatory hub in CRC by integrating signaling networks and metabolic pathways. Deeper mechanistic insights into spatiotemporal m6A regulation may accelerate the development of biomarkers and targeted therapies for precision CRC management.

Pancreatic fibrosis, a major pathological feature of chronic pancreatitis, is primarily driven by the abnormal activation of pancreatic stellate cells (PSCs) and excessive deposition of extracellular matrix. Traditional Chinese medicine (TCM) offers a holistic and synergistic approach to preventing and treating pancreatic fibrosis through multi-target regulation of PSC activation. This review systematically elucidates the mechanisms by which TCM—encompassing both bioactive monomers and compound formulations—modulates key signaling pathways involved in PSC activation, including the mitogen-activated protein kinase, transforming growth factor-β/Smad, platelet-derived growth factor, nuclear factor kappa B, and Wingless/β-catenin pathways. By simultaneously targeting these interconnected signaling networks, TCM strategies effectively inhibit PSC activation, attenuate inflammatory responses, and reduce extracellular matrix deposition. In contrast to single-target pharmacological inhibitors, TCM embodies a “multi-component, multi-pathway” therapeutic paradigm that aligns with the complex pathophysiology of pancreatic fibrosis. This review also draws comparative insights from liver fibrosis, highlighting conserved pathways and organ-specific regulatory contexts. Ultimately, TCM represents a promising integrative avenue for the prevention and treatment of pancreatic fibrosis, supported by growing preclinical evidence and aligned with the principles of holistic intervention.

Despite the emergence of new approaches in acute myeloid leukemia (AML) treatment in recent years, the overall prognosis remains poor. Particularly for elderly patients and relapsed/refractory cases, the five-year survival rate consistently remains below 30%. While traditional chemotherapy regimens can rapidly suppress tumor burden and alleviate clinical symptoms, they suffer from limitations such as insufficient targeting, prominent toxic side effects, and a tendency to induce drug resistance. Immunotherapy offers a novel therapeutic pathway for AML due to its advantages of precise targeting, long-lasting antitumor effects, and a controllable safety profile. However, single-agent immunotherapy demonstrates limited clinical response rates in AML and struggles to achieve complete tumor cell clearance. In this context, combination regimens of chemotherapy and immunotherapy are increasingly becoming the focus of research. This review aims to summarize the rationale and advances in the combination of immune checkpoint inhibitors, chimeric antigen receptor T-cell therapy, antibody-drug conjugates, bispecific antibodies, and cancer vaccines with chemotherapy for the treatment of AML. We have detailed the preclinical research and clinical trial progress of each combined regimen, analyzed the core challenges—including off-target toxicity, high tumor heterogeneity, and limited efficacy in specific AML subtypes—and further propose targeted solutions and future development directions, such as exploring novel specific antigens, developing multi-targeted drugs, and formulating precision individualized treatment plans. The clinical application of such combined strategies is attracting increasing attention. In conclusion, chemo-immunotherapy combinations represent a highly promising therapeutic paradigm for AML, harnessing the synergy of chemotherapy-mediated immune microenvironment remodeling and the specific antitumor activity of immunotherapies to overcome single-agent limitations and deliver meaningful survival benefits.

Fast inverse planning in radiosurgery planning is limited by an excessive number of isocenters, which is clinically hypothesized to be driven by the morphological irregularity of the target volume. This retrospective cross-sectional study aimed to empirically evaluate this hypothesis in vestibular schwannoma cases.

Consecutive patients diagnosed with vestibular schwannoma and receiving Gamma Knife radiosurgery in 2023 were included, and their treatment plans designed using the GammaPlan planning system were collected. Morphological irregularity–related parameters, including standard sphericity (SS), volume ratio sphericity (VRS), and the coefficient of variance of diameters (DCV), were calculated based on parameters provided by the system. Basic demographic and clinical data were collected to evaluate their impact on sphericity. The effects of different sphericity assessment methods on common treatment plan parameters were analyzed.

Treatment plans of 280 patients with vestibular schwannoma were collected. The SS, VRS, and DCV of the tumors were 0.85 (0.77–0.91), 0.46 ± 0.16, and 0.22 (0.14–0.34), respectively. Multivariate analysis showed that lesion volume, acoustic neuroma consensus on systems for reporting results grade, and age were significant factors influencing sphericity. All other planning parameters, except prescription dose and homogeneity index, were significantly correlated with sphericity. DCV was more closely correlated with SS than with VRS.

DCV may serve as a simple quantitative metric of target morphological irregularity, showing strong consistency with SS. Incorporating morphological irregularity into Gamma Knife treatment plan evaluation may help improve future planning strategies and support optimization of isocenter utilization.
