Single‐Nucleus Multi‐Omics Reveals Hypoxia‐Driven Angiogenic Programs and Their Epigenetic Control in Sinonasal Squamous Cell Carcinoma

Advanced Science, EarlyView.
Single‐nucleus multi‐omics profiling of sinonasal squamous cell carcinoma unveils a hypoxia‐driven angiogenic axis. A specific hypoxic tumor subpopulation orchestrates endothelial tip cell differentiation via epigenetically regulated ADM and VEGFA secretion.

Astrocytic PERK Deficiency Drives Prefrontal Circuit Dysfunction and Depressive‐Like Behaviors

Advanced Science, EarlyView.
Chen et al. show that the endoplasmic reticulum (ER) stress sensor PERK is downregulated in prefrontal cortex (PFC) astrocytes in major depressive disorder and in chronic‐stress mouse models. In young mice, astrocyte‐specific PERK loss reduces the synaptogenic cue thrombospondin‐1 (TSP1), leading to synaptic and circuit deficits and depressive‐like ...

Postoperative Stress Accelerates Atherosclerosis Through Inflammatory Remodeling of the HDL Proteome and Impaired Reverse Cholesterol Transport

Advanced Science, EarlyView.
The study shows that noncardiac surgical inflammation rapidly disrupts HDL function and cholesterol efflux in mice and human patients. Impaired reverse cholesterol transport after surgery drives rapid lipid accumulation, NETosis, and apoptosis within atherosclerotic plaques.

Dipiperazine‐Phenyl Derivatives Based on Convergent Molecular Platforms Can Reverse Multidrug Resistance in Gram‐Negative Bacteria by Inhibiting Efflux and Permeabilizing Cell Membranes

Advanced Science, EarlyView.
By integrating a convergent molecular platform strategy, this study designed a novel dual‐target C5 to combat multidrug‐resistant Gram‐negative bacteria. C5 synergistically enhances antibiotic efficacy by inhibiting efflux pumps and increasing bacterial membrane permeability.

Soft‐Drug‐Inspired MnSTF Nano‐Adjuvant for Safe and Synergistic cGAS–STING Activation in Tumor Immunotherapy

Advanced Science, EarlyView.
This study introduces MnSTF, a soft‐drug‐inspired nanoadjuvant that overcomes the systemic toxicity of STING agonists. Through Mn2+ coordination with an ENPP1 inhibitor, it enables safe cGAS‐STING activation, remodels the tumor immune microenvironment, and synergizes with radiotherapy or vaccines to elicit robust antitumor immunity.

Targeting DNA‐LNPs to Endothelial Cells Improves Expression Magnitude, Duration, and Specificity

Advanced Science, EarlyView.
Attaching antibodies against endothelial cell surface proteins redirects the delivery and expression of DNA‐lipid nanoparticles to organs of interest. Our targeted nanoparticles enable organ‐selective DNA expression in the endothelium of the lungs, brain, or spleen, providing a therapeutic platform for dozens of endothelial‐centric diseases.

Connexin43 Deficiency Leads to Ventricular Arrhythmias by Reprogramming Proline Metabolism

Advanced Science, EarlyView.
The study demonstrated that connexin43 (Cx43) knockout caused arrhythmic phenotype and decreased proline content in vitro and in vivo. Mechanistically, Cx43 interacts with the amino acid transporter SNAT2 (sodium‐dependent neutral amino acid transporter), and its deficiency disrupts proline transport and metabolism.
