Hostile microenvironment-driven oxygenator hydrogel with spatiotemporally feedback regulated hif-1α for accelerating diabetic wound healing

Diabetic wounds remain notoriously intractable due to a hostile microenvironment characterized by hyperglycemia, hypoxia, and oxidative stress. However, existing therapies often lack the ability to autonomously and sustainably remodel this pathological niche. Herein, a smart nano...

The SIMDA framework maps PIP2-binding sites regulating the KCNQ1 channel

Voltage-gated potassium channel KCNQ1 (Kv7.1) underpins cardiac repolarization, epithelial ion transport, and inner ear function. Its versatility arises from interactions with KCNE proteins, calmodulin (CaM), and the lipid phosphatidylinositol 4,5-bisphosphate (PIP2), yet the mol...

A Novel tRNA Half mt‐5’‐tiRNA‐Tyr Promotes Colorectal Cancer Proliferation via Inducing HARS2 Succinylation

Transfer RNA-derived small RNAs (tsRNAs) are a novel class of small non-coding RNAs abundant in the bloodstream of cancer patients and involved in various physiological and pathological processes. However, the regulatory mechanisms and clinical significance of tsRNAs in colorecta...

ElectrochemiluminescenceMicroscopy

Abstract Electrochemiluminescence (ECL) microscopy is an emerging imaging technology that combines electrochemistry with optical microscopy. It operates without external light excitation, effectively eliminating photobleaching, phototoxicity, and scattered light noise, and thus e...

P53 Competitively Binds P300 to Suppress HIF ‐1α/ TFRC ‐Mediated Ferroptosis and Promote Doxorubicin Resistance in Breast Cancer

ABSTRACT Doxorubicin (DOX) resistance limits the efficacy of chemotherapy in breast cancer, and suppression of ferroptosis may contribute to this process. This study investigated the role of the Tumor Protein P53 (P53)/E1A‐associated protein P300 (P300)/Hypoxia‐inducible factor‐1...

HomocamptothecinPayloads with Enhanced Potency forAntibody-Drug Conjugates

Abstract Camptothecin derivatives, exemplified by DXd, are a dominant class of payloads for antibody-drug conjugates (ADCs). Herein, we describe the design and synthesis of H2, a novel homocamptothecin featuring a simplified hydroxybutyl structure that circumvents the complex ass...

CXCR4-targeted dual softener for inducing senescence therapy in hepatic fibrosis

Hepatic fibrosis is a central pathological driver of chronic liver diseases, including metabolic dysfunction-associated steatotic liver disease and alcohol-related liver disease, which collectively impose a growing global health burden. Fibrosis is primarily mediated by persisten...

Gut microbiota-derived indoleacrylic acid ameliorates rheumatoid arthritis by preventing necroptosis of fibroblast-like synoviocytes and regulating macrophage polarization

Rheumatoid arthritis (RA) is associated with gut metabolite dysfunction, but the contribution of tryptophan-derived metabolites to RA remains fully uncharacterized. Here, we investigated the role of the gut microbiota-derived tryptophan metabolite indoleacrylic acid (IA) in exper...

Fructose directly remodels the translocase of the outer membrane to impair oxidative phosphorylation in podocytes

Excessive dietary fructose consumption contributes to the rapidly increasing prevalence of obesity, metabolic syndrome, and chronic kidney disease worldwide, and accumulating preclinical evidence has confirmed that excess fructose exposure provokes severe mitochondrial dysfunctio...

Lung tumour secretome and extracellular vesicles: mechanisms, biomarkers, and therapeutic opportunities

Lung cancer progression is governed not only by tumour-intrinsic genetic alterations but also by dynamic communication between tumour cells and the surrounding microenvironment. An important component of this communication is the tumour secretome, comprising soluble factors and e...

Radical 1,3-Difunctionalizationof β,γ-UnsaturatedKetones via Synergistic LMCT and RLT Photocatalysis

Abstract We report herein a simple and general photoinduced iron-catalyzed method that combines 1,2-functional group migration (1,2-FGM) with ligand-to-metal charge transfer (LMCT) and radical ligand transfer (RLT) to broaden the reaction profiles of alkene 1,3-difunctionalizatio...

Optimizationof a Second-Generation, Highly SelectivePolθ/PARP1 Dual Inhibitor with Improved Pharmacokinetics andPotent Activity against HR-Deficient Tumors

Abstract Dual inhibition of Polθ and PARP1 represents a promising precision therapy strategy for HR-deficient tumors. While our first-generation Polθ/PARP1 dual inhibitor 4 provided proof-of-concept, its further development was hampered by poor selectivity over PARP2 and metaboli...

Targeting breast cancer stem cells by restoring RBM38 function: mechanism and protein delivery therapy

Breast cancer stemness drives tumor progression and therapy resistance, yet the underlying mechanisms remain poorly understood. In this study, we observed that RBM38 expression gradually decreases during breast cancer progression in MMTV - PyMT transgenic mice. Using a model with...

Oral nano-delivery of a gut microbial metabolite enhances T cell stemness for cancer immunotherapy

Gut microbial metabolites play crucial roles in regulating systemic immunity, but their mechanisms and limited drug-like properties remain unresolved. Here we report an oral nano-formulation that leverages gut microbial metabolites to modulate T cell metabolism and amplify antitu...

Salt‐Controlled Multistep Phase Separation in Hydroxypropyl Cellulose Colloids for Sustainable Adhesives

ABSTRACT Phase separation is an evergreen subject that shapes our understanding of how order and functionality emerge from disordered complex soft matter systems. Here, we report on the salt‐regulated transition from isotropic liquid‐liquid phase separation to anisotropic liquid‐...

NIR-Activated Enteric Prodrug Microparticles for Bioimaging-Guided Chemotherapy of Colorectal Cancer

Colorectal cancer (CRC) remains a leading cause of cancer mortality worldwide. 5-Fluorouracil (5-FU) is a first-line chemotherapeutic widely used in CRC treatment, but its systemic administration often causes severe toxicity due to uncontrolled biodistribution. Herein, we present...
