Histone lactylation enhances GCLC expression and thus promotes chemoresistance of colorectal cancer stem cells through inhibiting ferroptosis

Cell Death and Disease
Colorectal cancer stem cells (CCSCs) play a critical role in mediating chemoresistance. Lactylation is a post-translational modification induced by lactate that regulates gene expression.

TRAF6 Lactylation in Glycolytic Macrophages Drives NF‐κB Signaling and M1 Polarization During Orthodontic Tooth Movement

Advanced Science, EarlyView.
Schematic diagram showing compressive stress triggers glycolytic reprogramming and lactate accumulation in macrophages. Lactate mediates TRAF6 lactylation at K171/K180 dual sites, which enhances its K63‐linked ubiquitination to activate the NF‑κB pathway and promote M1 polarization. This cascade drives orthodontic tooth movement (OTM) and alveolar bone

Both L-lactyl and D-lactyl enantiomers modify histones in mouse testis

Molecular & Cellular Proteomics
Abstract Dynamic histone post-translational modifications are crucial to precisely orchestrate gene expression programs. The recently discovered histone lysine lactylation has already been explored in various pathological contexts, but less in normal tissues.

Histone H3K18 Lactylation Promotes the Malignant Progression of Wilms Tumor via a PSRC1/AKT/HIF‐1α Positive Feedback Loop

Advanced Science, EarlyView.
In nephroblastoma, aberrant glycolysis drives lactate accumulation, which elevates histone H3K18 lactylation via p300. Lactylation of the PSRC1 promoter activates its transcription. PSRC1 competitively binds AKT, relieving PTEN‐mediated inhibition and triggering AKT/mTOR/HIF‐1α signaling.

Class I histone deacetylases catalyze lysine lactylation

Journal of Biological Chemistry
Abstract Metabolism and post-translational modifications (PTMs) are intrinsically linked and the number of identified metabolites that can covalently modify proteins continues to increase. This metabolism/PTM crosstalk is especially true for lactate, the product of anaerobic metabolism following glycolysis.

Histone H3 lysine 18 lactylation attenuates neuroinflammation and neurological damage by regulating microglial plxnb2 after ischemic stroke

Neurobiology of Disease
Microglia are major resident immune cells in the central nervous system and are actively involved in the pathogenesis of ischemic stroke. Histone lactylation confers macrophage homeostatic gene expressions and regulates physiological and immune-related ...

PEAR1 Promotes Glucose Metabolism Reprogramming in Sepsis‐Associated Acute Lung Injury via AARS1‐Mediated HIF‐1α Lactylation

Advanced Science, EarlyView.
This study revealed that a PEAR1/HIF‐1α/ glycolysis/lactate/H3K18la positive feedback loop in PMVECs that drives the development of S‐ALI. Mechanistically, PEAR1 mediates the binding of HIF‐1α to AARS1, leading to the lactylation of HIF‐1α, the primary lactylation site of which is K172.

Histone lactylation in macrophages is predictive for gene expression changes during ischemia induced-muscle regeneration

Molecular Metabolism
Objectives: We have previously shown that lactate is an essential metabolite for macrophage polarisation during ischemia-induced muscle regeneration. Recent in vitro work has implicated histone lactylation, a direct derivative of lactate, in macrophage ...

Strategies and mechanisms of precision genome engineering: From gene editing to genome writing

iMetaOmics, EarlyView.
In this review, we examined the progression of genome manipulation from stochastic nuclease‐mediated cutting toward precise editing and programmable genome writing. We discussed tools like multi‐kilobase RNA‐guided integrators and Artificial Intelligence (AI)‐designed effectors and showed how these advances enable researchers to treat genomes as ...

Positive feedback regulation between glycolysis and histone lactylation drives oncogenesis in pancreatic ductal adenocarcinoma

Molecular Cancer
Background Metabolic reprogramming and epigenetic alterations contribute to the aggressiveness of pancreatic ductal adenocarcinoma (PDAC). Lactate-dependent histone modification is a new type of histone mark, which links glycolysis metabolite to the ...
