Advanced Science, EarlyView.The DLST K409 succinylation mediated by CPT1A promotes OXPHOS and redox homeostasis through regulating enzyme activity, thereby promoting the malignant progression of LUAD. Notably, the succinylation of DLST can enhance the cuproptosis resistance by inhibiting its lipoylation.

Advanced Science, EarlyView.SOX2 upregulates KAT7 in glioma stem cells, where KAT7 deposits H3K14 acetylation at the RAC2 promoter to activate RAC2 transcription. RAC2‐GTP subsequently promotes PAK1/2/3 phosphorylation, increasing tricarboxylic acid cycle flux and mitochondrial respiration to support glioblastoma malignancy.

Advanced Science, EarlyView.Sepsis triggers hippocampal SIRT7 loss, promoting histone H2B succinylation and activation of the PD‐1/PD‐L1–PINK1 axis. This metabolic‐epigenetic cascade drives aberrant mitophagy and neuronal injury, ultimately causing cognitive deficits. Targeting SIRT7‐dependent succinylation offers a potential strategy to protect brain function during sepsis ...

Identification of Novel Protein Lysine Acetyltransferases in
mBio, 2018 Posttranslational modifications, such as Nε-lysine acetylation, regulate protein function. Nε-lysine acetylation can occur either nonenzymatically or enzymatically.

Advanced Science, EarlyView.A low dose of dexmedetomidine, delivered by ROS‐responsive nanoparticles, preferentially accumulates in the ischemic intestine and restores gut vascular barrier integrity after ischemia/reperfusion injury. This nanoparticle‐based strategy prevents bacterial translocation and liver damage without cardiorespiratory side effects, working through HDAC ...

Acetylation at α-tubulin K40 is the sole post-translational modification preferred to occur inside the lumen of hollow cylindrical microtubules. However, how tubulin acetyltransferases access the luminal K40 in micrometer-long microtubules remains ...

Co-translational, post-translational, and non-catalytic roles of N-terminal acetyltransferases [PDF]
, 2019 Recent studies of N-terminal acetylation have identified new N-terminal acetyltransferases (NATs) and expanded the known functions of these enzymes beyond their roles as ribosome-associated co-translational modifiers.

Advanced Science, EarlyView.A synthetic glycoconjugate vaccine based on a diacetylated Salmonella trisaccharide elicits broadly protective antibodies against four major human pathogenic serovars. Mechanistic studies identify 2,3‐di‐O‐acetylation of rhamnose as a critical determinant of antigen recognition and breadth of protection, establishing a new strategy for broad‐spectrum ...

Structure and Biosynthesis of Mangotoxin Produced by the Plant Pathogen Pseudomonas syringae
Angewandte Chemie, EarlyView.The structure of mangotoxin remained elusive for over two decades. Here, mangotoxin was isolated from the native producer, Pseudomonas syringae pv. syringae, and was determined to be an alkyne‐containing dipeptide. Mangotoxin inhibited the growth of multidrug‐resistant human pathogen Klebsiella pneumoniae.

Advanced Science, EarlyView.In this study, an efficient screening system is developed for plant metabolites to find a compound, 7‐epi‐10‐deacetyltaxol, inhibits tissue elongation. It suppresses plant growth through brassinosteroid and microtubule pathways. It is later applied to animal cells and human tumor organoids, resulting in similar cell division suppression. These findings
