NPR1 Promotes Lipid Droplet Lipolysis to Enhance Mitochondrial Oxidative Phosphorylation and Fuel Gastric Cancer Metastasis

Advanced Science, EarlyView.
NPR1 induces lipolysis of stored lipid droplet and enhances mitochondrial oxidative phosphorylation to fuel gastric cancer metastasis. Specifically, NPR1‐mediated activation of PKG directly phosphorylates and activates HSL at Ser855 and Ser951, thereby driving lipolytic processes.

SENP6 Maintains Mitochondrial Homeostasis by Regulating Mitochondrial Protein Import Through deSUMOylation of TOM40

Advanced Science, EarlyView.
SUMOylation regulates mitochondrial processes, but its impact on protein import remains unclear. TOM40 is identified, a mitochondrial outer membrane channel protein, as a substrate of deSUMOylase SENP6. TOM40 SUMOylation disrupts outer membrane complex assembly, inhibits protein import, and compromises mitochondrial homeostasis.

Lipid Droplet‐Organized MDM2‐Mediated P53 Degradation: A Metabolic Switch Governing Diet‐Driven Tumor Progression

Advanced Science, EarlyView.
Tumor‐associated TP53 inactivation correlates with lipid droplet (LD) accumulation. High‐fat diets drive Cyb5r3‐Myh9‐mediated p53 enrichment on LD surfaces, accelerating its degradation while upregulating LD‐promoting factor CD36 expression to establish a feed‐forward loop. LD suppression or dietary intervention restores p53 and inhibits tumorigenesis,

Deciphering the Role and Mechanism of Decidual Monocyte‐Derived Macrophage Infiltration in Obstetric Antiphospholipid Syndrome at Single‐Cell Resolution

Advanced Science, EarlyView.
This study uncovers a novel mechanism and therapeutic targets in obstetric antiphospholipid syndrome (OAPS). Antiphospholipid antibody/ß2‐glycoprotein I complex boosts CCL2 and TNF‐α expression in decidual macrophages via TLR4‐NF‐κB. CCL2 accumulates on endothelial surfaces via ACKR1, recruiting monocyte‐derived CCR2+ macrophages, driving inflammation,

STING COPII ER Export Trafficking and Signaling Primed by Phosphorylation Switches

Advanced Science, EarlyView.
This schematic outlines STING trafficking and signaling via coat protein II (COPII)‐mediated endoplasmic reticulum (ER) export. Following cyclic GMP‐AMP (cGAMP) stimulation, TANK‐binding kinase 1 (TBK1) activates on COPII vesicles, partially dissociating into the cytosol to phosphorylate ER‐localized STING, creating pSGME/pFS COPII‐sorting motifs ...
