SIRT5‐Mediated Desuccinylation of ACAA2 Protects Against Calcium Oxalate‐Induced Kidney Injury by Regulating Fatty Acid Oxidation to Suppress Mitochondrial Oxidative Injury and Ferroptosis

open access: yesAdvanced Science, EarlyView.
The SIRT5/ACAA2 axis maintains lipid metabolic homeostasis in RTECs by promoting ACAA2 desuccinylation and preserving its stability and enzymatic activity, thereby sustaining FAO and limiting PUFA and PUFA‐containing phospholipid accumulation. Under CaOx stress, SIRT5 downregulation impairs FAO, promotes oxidative stress and ferroptosis, and enhances ...

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 ...

Targeted‐Penetrating Biomimetic Hybrid Transfersomes for Enhanced Transdermal Gene Transfection in Hypertrophic Scar Therapy

open access: yesAdvanced Science, EarlyView.
Hypertrophic scar fibroblasts membrane‐hybridized cationic transfersomes enable efficient loading and transdermal delivery of TGF‐β1 siRNA through multiple skin penetration pathways. The biomimetic platform enhances homotypic targeting, transfection, and immune evasion, suppresses TGF‐β1‐driven fibrotic signaling, and reduces extracellular matrix ...

Ilexoside K Ameliorates Atherosclerosis by Suppressing CD72hi Macrophages and Blocking CXCL12–CXCR4 Axis to Inhibit Endothelial Pyroptosis

open access: yesAdvanced Science, EarlyView.
CD72hi macrophages drive endothelial pyroptosis and accelerate atherosclerosis through CXCL12–CXCR4‐mediated immune–vascular crosstalk. Ilexoside K suppresses this pathogenic communication by modulating CXCR4‐dependent endothelial responses, reducing inflammation and plaque progression. These findings reveal a macrophage–endothelial regulatory axis and

Nuciferine Suppresses Inflammatory Hepatocarcinogenesis by Targeting cPLA2‐Dependent Arachidonic Acid Metabolism

open access: yesAdvanced Science, EarlyView.
Nuciferine directly binds the C2 domain of cPLA2, impairing its Ca2+‐dependent membrane translocation and activation. By suppressing arachidonic acid release and downstream pro‐inflammatory eicosanoid production, nuciferine attenuates NF‐κB signaling and inflammatory hepatocarcinogenesis, revealing cPLA2 as a direct molecular target underlying its ...
