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.

Synthesis of Large‐ and Medium‐Sized Heterobiaryl Atropisomeric Rings and Atropopeptides by Catalytic Intramolecular SNAr

Angewandte Chemie, EarlyView.
Catalytic, intramolecular N‐heterocycle arylation by nucleophilic aromatic substitution (SNAr) is now available for synthesis of highly strained macrocycles and medium‐sized heterobiaryl atropisomeric rings, including atropopeptides. Key to the approach is the ability to generate a strong base catalytically, taking advantage of base‐embedding ...

Determination of Gene‐Level Fitness Contributions Across the Mucin‐Utilization Network of Bacteroides thetaiotaomicron

Advanced Science, EarlyView.
Genome‐wide CRISPRi and RNA‐seq resolve how B. thetaiotaomicron converts host mucosal glycans into fitness. The study reveals a layered mucin‐utilization architecture in which capsular polysaccharides constrain surface access, extracellular CAZymes and peptidases show functional redundancy, and intracellular catabolic pathways create discrete metabolic

Gain‐of‐Function Engineering of the NifEN Scaffold Into a Self‐Assembling Nitrogenase

Angewandte Chemie, EarlyView.
From scaffold to enzyme: Systematic engineering of the cofactor maturation scaffold NifEN reconstructs the P→M electron relay along with cofactor coordination and proton gating at the S2B site, converting NifEN into a functional nitrogenase capable of ATP‐dependent N2 reduction both in vitro and in vivo.

Hepatic Lipid Stress Drives Metabolic Dysfunction‐Associated Steatohepatitis Progression through FTO O‐GlcNAcylation‐Induced m6A Demethylation of HRAS

Advanced Science, EarlyView.
Lipid stress drives O‐GlcNAcylation of the m6A demethylase FTO at Ser195, enhancing its stability and demethylase activity. This modification removes m6A from HRAS mRNA, preventing its degradation and activating PI3K/AKT signaling to promote hepatic steatosis and inflammation.
