SAT1‐Induced Spermidine Depletion Potentiates Food Allergy

open access: yesAdvanced Science, EarlyView.
Spermidine depletion, driven by upregulated spermidine/spermine N1‐acetyltransferase (SAT1), potentiates food allergy by promoting mast cell degranulation through autophagy suppression. SAT1 physically interacts with the long noncoding RNA Cdk19os to inhibit Atg5 and Atg7, disrupting autophagic flux.

Multimodal Imaging of Hypoxia, Metabolism and pH in Feline Sarcoma Using Hyperpolarized 13C MRI and PET

open access: yesAdvanced Science, EarlyView.
This work presents a clinically deployable simultaneous PET/MRI workflow which integrates hyperpolarized 13C imaging of metabolism and extracellular pH with [18F]FMISO PET to characterize hypoxia, acidosis, and metabolic reprogramming in feline sarcoma.

FBP1‐Mediated Compartmentalization of Glycolytic Enzyme Complexes Suppresses PKM2 Function to Ameliorate MASLD Progression

open access: yesAdvanced Science, EarlyView.
In normal hepatocytes, FBP1 forms compartmentalized complexes with PKM2, ENO1, and LDHA independent of its catalytic activity, inhibiting PKM2 activity and restricting excessive glycolysis. During MASLD progression, FBP1 downregulation markedly reduces the abundance of these complexes and releases the “hijacked” glycolytic enzymes, leading to PKM2 ...

Ciliary Membrane Lipid Homeostasis in Health and Disease

open access: yesAdvanced Science, EarlyView.
This review systematically delineates the distinct lipid landscapes of ciliary membranes, including the spatial organization of phosphoinositides, cholesterol, and sphingolipids. It elucidates how these lipids orchestrate ciliogenesis, signal transduction, and membrane dynamics in cilia beating, and highlights how their dysregulation drives ...

CXCL3 Antagonism Reverses Systemic Antitumor Immune Memory Impairment Associated With High Tumor Burden and Sensitizes Anti‐PD‐1 Therapy

open access: yesAdvanced Science, EarlyView.
This study reveals that large tumors secrete more chemokine CXCL3, which recruits immunosuppressive neutrophils to the periphery, thereby impairing the activation and memory of systemic tumor‑reactive CD8+ T cells. CXCL3 antagonism restores systemic immune memory and enhances the antitumor efficacy of anti‑PD‑1 therapy, offering a potential strategy to
