FADS2‐STING Signaling in Sertoli Cells Orchestrates Collagen Deposition and Germ Cell Necroptosis in Idiopathic Non‐Obstructive Azoospermia

Advanced Science, EarlyView.
In Sertoli cells of iNOA testes, downregulation of FADS2 activates STING, promoting collagen deposition and peritubular fibrosis while increasing germ‐cell susceptibility to necroptosis. Supplementation with FADS2‐derived PUFAs (GLA and DHA) inhibits STING, alleviates collagen accumulation, and facilitates the recovery of spermatogenesis.

SUMOylated DDX3 Promotes HBV Replication and Tumor Growth of Hepatocellular Carcinoma via TRIM28‐DDX3‐KLF4α Signaling Axis

Advanced Science, EarlyView.
TRIM28 binds to DDX3 protein to catalyze the SUMOylation of DDX3 (S‐DDX3), thus the S‐DDX3 involves in aberrant alternative splicing of KLF4 mRNA, and the splicing variant KLF4α‐mediated cell cycle and signal transduction, weakens tumor suppressor function of DDX3 protein, which promotes progression of HBV‐HCC.

A Citrulline‐Functionalized Patch Coordinates Macrophage NRF2 Signaling and Arginine Metabolism for Tendon‐to‐Bone Repair

Advanced Science, EarlyView.
A locally implanted patch combines citrulline‐functionalized carbon dots, a thioketal‐containing membrane coating from tendon‐derived stem cells, and aligned core–shell fibers. In macrophages, the patch reduces inflammatory markers and enhances antioxidant signaling through nuclear factor erythroid 2‐related factor 2 (NRF2); in rats and rabbits, it ...

ALDH2 Deficiency Promotes Mitochondrial Oxidative Stress and Adverse Limb Outcomes via VDAC–HSP60 Signaling

Advanced Science, EarlyView.
ALDH2 deficiency promotes 4‐HNE accumulation, resulting in covalent modification of HSP60, disruption of its oligomeric assembly, and VDAC1‐dependent release of HSP60 from mitochondria to the cytosol. Pharmacological activation of ALDH2 preserves HSP60 proteostasis and mitochondrial integrity, whereas the clinical association between the ALDH2 rs671 ...

Bacillus Licheniformis‐Induced Cognitive Decline in Mice Linking Gut Microbiota Dysbiosis, Metabolic Perturbations, and Hippocampal Neuroinflammation

Advanced Science, EarlyView.
Chronic oral administration of specific probiotic strains triggers gut microbiota dysbiosis and systemic metabolic perturbations in mice. Multi‐omics profiling reveals subsequent hippocampal glial remodeling and neuroinflammation, which are linked to cognitive impairment.
