Post-translational toxin modification by lactate controls Staphylococcus aureus virulence

Nature Communications
Diverse post-translational modifications have been shown to play important roles in regulating protein function in eukaryotes. By contrast, the roles of post-translational modifications in bacteria are not so well understood, particularly as they relate ...

Glycolytic reprogramming and cell-specific lactylation in asthma: an evidence-graded framework for testable metabolic-epigenetic profiles

Frontiers in Immunology
Asthma is metabolically heterogeneous, but existing syntheses often place patient observations, animal perturbations, cross-disease mechanisms, and therapeutic concepts on the same evidentiary plane.

AARS1 and AARS2: From Protein Synthesis to Lactylation-Driven Oncogenesis

Aminoacyl-tRNA synthetases (AARSs), traditionally recognized for their essential role in protein synthesis, are now emerging as critical players in cancer pathogenesis through translation-independent functions.

Organ‐Resolved Host Proteomic and Post‐Translational Modification Landscapes in a Mouse Model of Talaromyces marneffei Infection

iMetaMed, EarlyView.
We presented an organ‐resolved, multiple PTM remodeling atlas of systemic T. marneffei infection, integrating quantitative proteome, phosphoproteome, ubiquitinome, acetylome, and lactylome data across the liver, lung, and spleen. The atlas delineated organ‐specific PTM signatures and a functional convergence of divergent modification types on immune ...

OXCT1‐driven succinylation of PSMG3 stabilizes the proteasome to facilitate picornavirus replication

iMetaOmics, EarlyView.
Upon entering the pig, foot‐and‐mouth disease virus (FMDV) regulates host glycolysis and the citrate cycle by modulating the expression of metabolic enzymes, resulting in changes in post‐translational modifications (PTMs) including succinylation, lactylation, crotonylation, acetylation, and phosphorylation.

Polydatin Alleviates APAP‐Induced Hepatotoxicity by Targeting C/EBPβ to Suppress the NLRP3 Inflammasome Signaling Pathway

iNew Medicine, EarlyView.
PD alleviates APAP‐induced ALI by inhibiting the NLRP3 inflammasome signaling pathway. C/EBPβ is identified as a direct target via multimethod validation. PD promotes the deacetylation of C/EBPβ via Sirt1. The Sirt1/C/EBPβ/NLRP3 signaling axis is defined for PD's hepatoprotective effect.

Rhaponticin Blocks Glycolysis‐Mediated Histone Lactylation to Suppress Tongue Squamous Cell Carcinoma via HIF‐1α Activity Inhibition

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Tongue squamous cell carcinoma (TSCC) often develops therapeutic resistance. Metabolic reprogramming, particularly the glycolysis/lactate/histone lactylation axis, is a critical driver of tumor progression and therapy resistance. This study investigated the anti‐tumor mechanism of Rhaponticin (Rha), focusing on the metabolic/epigenetic axis ...

Lactate and Lactylation: What We Know and What We Expect in Tumour Progression

Cell Proliferation, EarlyView.
Lactate and lactylation in cancer cells have been shown to accelerate tumour development in various ways, including stemness generation, metabolic dysregulation, cell death, chemotherapy resistance, and cell cycle disorder. In addition, lactate and lactylation promote angiogenesis and create an immunosuppressive microenvironment, which promotes tumour ...

Epigenetic and Metabolic Changes That Drive Trained Immunity in Response to Microbes and Vaccines

Immunology, EarlyView.
This graphical abstract illustrates how microbial products, vaccines and microbial metabolites activate pattern‐recognition receptor signalling, inducing metabolic rewiring and epigenetic remodelling. These changes establish long‐lasting trained immunity through the functional reprogramming of haematopoietic progenitors and innate immune cells, thereby

LGR6 couples maresin 1 signaling to glycolytic flux and protein lactylation for the rescue of diabetic cardiomyopathy

Journal of Diabetes Investigation, EarlyView.
MaR1 activates LGR6‐AMPK signaling to restore metabolic flexibility in diabetic hearts. Glycolytic recovery replenishes intracellular lactate to rescue protective protein lysine lactylation, which reactivates PINK1/Parkin‐mediated mitophagy to eliminate damaged mitochondria.
