Development and validation of a glycolysis-associated gene signature for predicting the prognosis, immune landscape, and drug sensitivity in bladder cancer.

Background: Bladder cancer (BCa) is one of the most common malignancies worldwide, and its prognostication and treatment remains challenging. The fast growth of various cancer cells requires reprogramming of its energy metabolism using aerobic glycolysis as a major energy source. However, the prognostic and therapeutic value of glycolysis-related genes in BCa remains to be determined.

Assembly of ceria-Nrf2 nanoparticles as macrophage-targeting ROS scavengers protects against myocardial infarction.

Myocardial infarction (MI) is a leading cause of morbidity and mortality worldwide, and mitigating oxidative stress is crucial in managing MI. Nuclear factor erythroid 2-related factor 2 (Nrf2) plays a critical role in combating oxidative stress and facilitating cardiac remodeling post-MI. Here, we engineered Cerium oxide (CeO) nanoparticle-guided assemblies of ceria/Nrf2 nanocomposites to deliver Nrf2 plasmids.

Pulmonary fibrosis significantly contributes to the pathogenesis of acute respiratory distress syndrome (ARDS), markedly increasing patient mortality. Despite the established anti-fibrotic effects of mesenchymal stem cells (MSCs), numerous challenges hinder their clinical application. A recent study demonstrated that microvesicles (MVs) from MSCs (MSC-MVs) could attenuate ARDS-related pulmonary fibrosis and enhance lung function hepatocyte growth factor mRNA transcription.

Exosomal miR-224-3p promotes lymphangiogenesis and lymph node metastasis by targeting GSK3B in gastric cancer.

Rescue RM/CS-AKI by blocking strategy with one-dose anti-myoglobin RabMAb.

Rhabdomyolysis or Crush syndrome-related AKI (RM/CS-AKI) has high mortality, and there is no effective early on-site treatment method. The critical pathogenic factor of RM/CS-AKI is the excessive free myoglobin (Mb) in blood circulation. Here, based on the concept of creating a "mobile barrier", we develop an anti-Mb rabbit monoclonal antibody (RabMAb) with high specificity, affinity, stability, and broad species reactivity.

Autophagy-targeted therapy for pulmonary inflammation by 2D MX (M = W, Nb; X = S, Se) nanosheets.

For biomedical applications, two-dimensional transition metal dichalcogenides (2D TMDCs) are often combined with other elements or functionalized with specific surface ligands, while their intrinsic biological activities are not yet fully understood. This study investigates the anti-inflammatory potential of four unmodified 2D TMDCs, including WS, WSe, NbS, and NbSe nanosheets, in LPS-activated MH-S cells in vitro and in a mouse model of pulmonary inflammation in vivo. Despite their varying compositions, these 2D TMDCs exhibited comparable anti-inflammatory effects in LPS-activated MH-S cells.

A multicenter study of neurofibromatosis type 1 utilizing deep learning for whole body tumor identification.

Deep-learning models have shown promise in differentiating between benign and malignant lesions. Previous studies have primarily focused on specific anatomical regions, overlooking tumors occurring throughout the body with highly heterogeneous whole-body backgrounds. Using neurofibromatosis type 1 (NF1) as an example, this study developed highly accurate MRI-based deep-learning models for the early automated screening of malignant peripheral nerve sheath tumors (MPNSTs) against complex whole-body background.

Supramolecular discrimination and diagnosis-guided treatment of intracellular bacteria.

Pathogenic intracellular bacteria pose a significant threat to global public health due to the barriers presented by host cells hindering the timely detection of hidden bacteria and the effective delivery of therapeutic agents. To address these challenges, we propose a tandem diagnosis-guided treatment paradigm. A supramolecular sensor array is developed for simple, rapid, accurate, and high-throughput identification of intracellular bacteria.

Background: Changes in cerebral blood flow (CBF) may contribute to the initial stages of the pathophysiological process in patients with Alzheimer's disease (AD). Hypoperfusion has been observed in several brain regions in patients with mild cognitive impairment (MCI). However, the clinical significance of CBF changes in the early stages of AD is currently unclear.

This study evaluated the efficacy of butylphthalide in preventing cognitive decline over a 12-month period in patients with ischaemic stroke.

Thrombolytic efficacy and safety of recombinant scu-PA in a rabbit retinal vein occlusion model.

Retinal vein occlusion (RVO) has become the second most common retinal vascular disease after diabetic retinopathy. Existing therapeutic approaches, including intravitreal injection of antivascular endothelial growth factors (anti-VEGFs) and/or glucocorticoids and laser therapy, primarily address secondary macular edema and neovascularisation. However, these strategies do not address the underlying cause of the disease and may have harmful side effects.

The natural product micheliolide promotes the nuclear translocation of GAPDH via binding to Cys247 and induces glioblastoma cell death in combination with temozolomide.

Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is significantly upregulated in glioblastoma (GBM) and plays a crucial role in cell apoptosis and drug resistance. Micheliolide (MCL) is a natural product with a variety of antitumour activities, and the fumarate salt form of dimethylamino MCL (DMAMCL; commercial name ACT001) has been tested in clinical trials for recurrent GBM; this compound suppresses the proliferation of GBM cells by rewiring aerobic glycolysis. Herein, we demonstrated that MCL directly targets GAPDH through covalent binding to the cysteine 247 (Cys247) residue.

Arctiin suppress Th17 cells response and ameliorates experimental autoimmune uveitis through JAK/STAT signaling.

Conventional treatments for autoimmune uveitis, such as corticosteroids and systemic immunosuppressants, often result in adverse side effects, prompting the need for therapies targeting specific molecular pathways. This study investigates the effects of Arctiin, known for its diverse biological properties, on experimental autoimmune uveitis (EAU) through its action on Th17 cells and the JAK/STAT signaling pathway. Our findings reveal that Arctiin significantly alleviates EAU by reducing clinical scores, inflammatory cell infiltration, and levels of inflammatory cytokines like IL-17 and TNF-α in the eye.
