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 ...

This review systematically elaborates on the mechanisms underlying physiological regulation and pathological dysregulation of biomolecular phase separation. It also summarizes advances in phase‑separation‑targeted therapeutic strategies and the design of functional biomaterials inspired by this process.

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

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 ...

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.
