Persistent Zn2+ Influx‐Mediated Deacetylation of ANXA2 Regulates the “Zn2+‐Autophagic Flux” and Alleviates Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
Zinc transporter SLC39A14 sustains intracellular Zn2+ levels to activate SIRT3‑dependent ANXA2 deacetylation at K302. This modification weakens ANXA2‑mTOR binding and releases autophagic‑flux suppression in nucleus pulposus cells. Dysregulated Zn2+ homeostasis disrupts this axis to drive intervertebral disc degeneration.

Zinc Fingers as Programmable Metalloprotein Scaffolds for Altering Pathogenic Biomolecular Phase Transitions

open access: yesAdvanced Science, EarlyView.
Modular zinc finger (ZF) metalloproteins function as programmable biomolecular scaffolds that modulate pathogenic amyloid assembly. Through direct protein–protein interactions, ZF arrays alter amyloid phase behavior and redirect β‐sheet fibrillization toward nontoxic aggregates.

Remote Ischemic Post‐Conditioning Preserves the Neurovascular Unit by Brain‐Derived Gas6 That Drives Monocyte‐Derived Macrophage Reprogramming via Axl and Vimentin after SAH

open access: yesAdvanced Science, EarlyView.
Subarachnoid hemorrhage (SAH) triggers monocyte‐derived macrophage (MDM) infiltration and M1‐like polarization via Vimentin upregulation, leading to neurovascular unit disruption and cognitive dysfunction. Remote ischemic postconditioning (RIPostC) upregulates neuronal Gas6, which activates Axl on MDMs to downregulate Vimentin and drive reparative M2 ...

Transfer RNA‐Derived Small RNA‐5’tiRNAGln Drives HNRNPC Phase Separation to Promote Breast Cancer Bone Metastasis by Regulating IGF1R

open access: yesAdvanced Science, EarlyView.
This study reveals that 5'tiRNA‐Gln interacts with hnRNPC to promote IGF1R liquid‐liquid phase separation, which drives ERK1/2 signaling activation, EMT, and breast cancer bone metastasis. These findings highlight a novel mechanism of breast cancer bone metastasis and potential therapeutic target in metastatic breast cancer.

TNF receptor–related factor 3 inactivation promotes the development of intrahepatic cholangiocarcinoma through NF‐κB‐inducing kinase–mediated hepatocyte transdifferentiation

open access: yesHepatology, EarlyView., 2022
Abstract Background and Aims Intrahepatic cholangiocarcinoma (ICC) is a deadly but poorly understood disease, and its treatment options are very limited. The aim of this study was to identify the molecular drivers of ICC and search for therapeutic targets.

A structural phylogenetic tree of Rad52 and its annealase superfamily

open access: yesComputational and Structural Biotechnology Journal
Rad52, a highly conserved eukaryotic protein, plays a crucial role in DNA repair, particularly in double-strand break repair. Recent findings reveal that its distinct structural features, including a characteristic β-sheet and β-hairpin motif, are shared
