Nuclear Translocation of PFKFB3 Promotes Disuse‐Induced Muscle Atrophy via Scaffolding Nedd4‐Mediated JunB Ubiquitination

open access: yesAdvanced Science, EarlyView.
Disuse‐induced muscle atrophy is driven by a non‐metabolic, nuclear function of the enzyme PFKFB3. Acting as a scaffold, PFKFB3 facilitates Nedd4‐mediated ubiquitination and degradation of the anti‐atrophy transcription factor JunB. Inhibiting this novel PFKFB3–Nedd4–JunB signaling axis stabilizes JunB and alleviates muscle wasting, revealing a highly ...

Restores Aβ Clearance by Overcoming PCSK9–LRP1 Dysregulation and TRIB3‐Mediated Autophagy Blockade in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
PCSK9 upregulation in cerebrovascular endothelial cells and microglia destabilizes the Aβ transporter LRP1, while TRIB3‐associated autophagy blockade further limits intracellular Aβ degradation. A RAP‐modified tea‐polyphenol nanoparticle co‐delivers siPCSK9 and siTRIB3 to restore LRP1‐mediated Aβ efflux and autophagy‐dependent degradation, reducing Aβ ...

Extracellular Vesicle Packaged TDP43 Derived From ECs Exacerbates Cigarette Tar‐Related Atherosclerosis Progression via Enhancing Macrophage Extracellular Traps

open access: yesAdvanced Science, EarlyView.
Cigarette tar triggers EC‐derived EVs carrying TDP43, which binds VDAC1 to boost MAMs, mitochondrial Ca2+ overload, and METs formation in macrophages, accelerating smoking‐related AS progression, while retinoic acid binds TDP43 to block this pathogenic cascade.
