Neonatal Sevoflurane Exposure Induces Long‐Term Cognitive Impairment via Epigenetically Mediated MMP9 Activation and Perineuronal Net Disruption in the Hippocampal CA2

open access: yesAdvanced Science, EarlyView.
Hippocampal CA2 perineuronal nets ensheathing excitatory pyramidal neurons are selectively vulnerable to repeated neonatal sevoflurane exposure. Epigenetic upregulation of MMP9 via reduced H3K27me3 disrupts PNN integrity, impairs BDNF–TrkB signaling, and causes synaptic protein loss and dendritic spine deficits, leading to persistent social and spatial

Early‐Life Manganese Overexposure Activates Microglial Phagocytosis through the YY1/TREM2 Axis Leading to Hippocampal Synaptic Remodeling in Mice

open access: yesAdvanced Science, EarlyView.
Early‐life manganese exposure induces behavioral deficits and aberrant hippocampal synaptic remodeling by enhancing microglial phagocytosis in young adult male mice. Mechanistically, manganese promotes Yin Yang 1 (YY1)/triggering receptor expressed on myeloid cells 2 (TREM2) signaling through enhanced HIF1α‐mediated transcription and suppressed SMURF2 ...

Context‐Dependent Inverse Association of Glucose–Lipid Metabolic Status With Anemia: Evidence From Multinational Multicohort Analyses

open access: yesAdvanced Science, EarlyView.
Across six multinational cohorts, higher triglyceride–glucose index values are consistently associated with lower prevalent and incident anemia, despite their established adverse cardiometabolic significance. This inverse relationship varies across inflammatory, cardiovascular, and renal contexts, suggesting that glucose–lipid metabolic status carries ...

Metabolic Signatures for Liver Cancer Diagnosis and Mechanistic Insights: A Large‐Scale, Multicenter Study

open access: yesAdvanced Science, EarlyView.
A large‐scale multicenter serum metabolomics study (13 centers, n = 2,149) identified a 9‐metabolite + AFP diagnostic signature for liver cancer (AUC = 0.93). Among the signature, nicotinamide (NAM) was validated as an oncometabolite: NAM enhances NAD+ synthesis, activating SIRT1 to deacetylate and stabilize HIF1α, thereby driving glycolysis, MAPK ...

Epithelial SLC25A20 Deficiency Drives Immunosuppressive Neutrophil Remodeling via ARG1 Palmitoylation to Promote Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
SLC25A20 deficiency in tumor cells compromises mitochondrial LCFA transport, which suppresses FAO and drives compensatory release of palmitic acid‐enriched lipids into the TME. These tumor‐derived palmitic acids are taken up by TANs, promoting ZDHHC18‐catalyzed ARG1 palmitoylation.

Oral Astilbin Nanogels Modulate Senescence‐Associated CD4+ T Cells and Promote Treg Induction in Aged Mice with Colitis

open access: yesAdvanced Science, EarlyView.
Fluorinated β‐glucan/pectin nanogels enable colon‐targeted oral delivery of astilbin through gastrointestinal protection, β‐glucanase‐responsive release, mucus penetration, and prolonged retention. The released astilbin attenuates senescence‐associated features of CD4+ T cells and promotes Treg responses, while the nanogel matrix modulates the gut ...
