Bone Marrow Macrophage STING Signaling is a Direct Nexus Linking Marrow Adipose Expansion to NAD+ Depletion and Osteogenic Decline in Skeletal Aging

Advanced Science, EarlyView.
This study reveals that during skeletal aging, bone marrow adipocyte‐derived sDPP4 primes STING signaling in macrophages. In combination with mitochondrial DNA, this signaling activates CD38 and depletes local NAD+/NMN, thereby impairing osteogenesis.

Phase Separation of SF3B1 Serves as a Critical Post‐Transcriptional Regulator During Early Mouse Embryogenesis

Advanced Science, EarlyView.
Phase separation of SF3B1 acts as a key regulatory mechanism for dynamic alternative splicing throughout early mouse embryogenesis. Its absence triggers extensive splicing errors, which induce persistent DNA damage, defective cell cycle progression, and failed cell lineage commitment, and ultimately hinder the normal growth and development of ...

Prion‐Like Protein LENG8‐Mediated Nucleation Drives Stress Granule Assembly

Advanced Science, EarlyView.
LENG8 is a newly identified stress granule (SG) nucleator required for SG assembly. Following stress, nuclear LENG8 granules disassemble, allowing LENG8 to translocate into the cytoplasm and form independent nucleation foci. These foci fuse with canonical early G3BP1/TIA1 seeds via LENG8‐TIA1 binding to drive SG maturation.

Lyssavirus Nucleoprotein Induces GPAT4‐Mediated CYB5R1 Depalmitoylation to Suppress Ferroptosis and Promote Viral Replication

Advanced Science, EarlyView.
Lipid metabolism plays a vital role in viral infections. Here, we reveal that the lyssavirus N protein regulates GPAT4 to induce lipid droplet biogenesis, restricting CYB5R1 palmitoylation and reducing ferroptosis susceptibility to ultimately promote viral replication.

SAV1 in Cooperation With FKBP52 Participates in Implantation

Advanced Science, EarlyView.
The MST‐SAV1 complex modulates FKBP52 phosphorylation to fine‐tune PR activity, ensuring timely uterine transition to receptivity under estrogen signaling for implantation. Stromal SAV1 scaffolds MST1/2‐mediated FKBP52 phosphorylation via noncanonical Hippo to promote PR activity.

RBM25 Drives Hepatocellular Carcinoma Progression by Stabilizing YAP Through Regulating Oncogenic Splicing‐switch of MYPT1

Advanced Science, EarlyView.
This study establishes that the RBM25‐PRPF40A interaction modulates MYPT1 splicing, promoting the production of the oncogenic long isoform. This isoform stabilizes YAP by suppressing its phosphorylation and subsequent proteasomal degradation, ultimately accelerating tumor growth.

Aspirin‐Derived Salicyl‐CoA Drives Histone Lysine Salicylation Regulated by CBP and SIRT2

Advanced Science, EarlyView.
Aspirin‐derived salicyl‐CoA serves as a previously unrecognized acyl donor for protein lysine salicylation. This study identifies histone lysine salicylation as a reversible epigenetic modification regulated by CBP and SIRT2, expanding the biochemical actions of aspirin beyond its canonical acetylation‐dependent mechanisms and providing a new framework
