Sarbecoviruses Suppress Innate Immunity by Recruiting PPM1A to Modulate STAT2 and ORF9b Phosphorylation

Advanced Science, EarlyView.
Sarbecovirus ORF9b recruits host phosphatase PPM1A to suppress innate immunity through dual mechanisms. PPM1A directly dephosphorylates ORF9b to sustain its activity and indirectly downregulates STAT2 phosphorylation to impair interferon signaling. Pharmacological inhibition of PPM1A restores antiviral responses and limits sarbecovirus replication ...

PLOD1 Catalytic Activity Stabilizes ENO1 by Limiting FBXW7‐dependent Degradation to Promote Glycolysis and TMZ Resistance in Glioblastoma

Advanced Science, EarlyView.
PLOD1 interacts with ENO1 and limits its FBXW7‐dependent ubiquitination and proteasomal degradation through a mechanism requiring PLOD1 catalytic activity. ENO1 stabilization sustains glycolysis, promoting glioblastoma cell proliferation, migration, and temozolomide resistance.

CD112 Lactylation Drives Dual Immune Evasion From CD8+ T Cells and NK Cells

Advanced Science, EarlyView.
AARS2 functions as an intracellular lactate sensor and lactyltransferase, catalyzing CD112 K412 lactylation to block ubiquitination‐dependent degradation and stabilize CD112. This pathway suppresses CD8+ T‐cell and NK‐cell cytotoxicity, enabling dual immune evasion.

Intermittent Fasting Reduces Taurine Availability and Promotes Antitumor Immunity Through PERK Attenuation‐Associated Paraptosis‐Like Cell Death in Colorectal Cancer

Advanced Science, EarlyView.
This study identifies reduced taurine availability as a mediator of intermittent fasting in colorectal cancer and shows that taurine interacts with GRP78 to maintain PERK abundance post‐transcriptionally. It further shows that taurine depletion destabilizes PERK, induces immunogenic paraptosis, remodels the tumor microenvironment toward a CD8+ T cell ...

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

Advanced 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.
