The role of protein lactylation in brain health and disease: current advances and future directions

Cell Death Discovery
Lactate, the end product of glycolysis, plays a crucial role in cellular signaling and metabolism. The discovery of lactylation, a novel post-translational modification, has uncovered the role of lactate in regulating diseases, especially in the brain ...

Histone Lactylation Drives WNK1 Expression to Promote Esophageal Squamous Cell Carcinoma Progression Through Histone H3 Ser10 Phosphorylation

Advanced Science, EarlyView.
In brief. Yan et al. demonstrated that the excess lactate produced by the enhanced glycolysis pathway in esophageal cancer can lactylate H3K23, H3K23la can be enriched in the WNK1 promoter region to promote WNK1 expression, thereby increasing the phosphorylation of the p‐H3 Ser10 site, and p‐H3S10 can be enriched in the AKT1 promoter region to promote ...

MeCP2 Lactylation Protects against Ischemic Brain Injury by Transcriptionally Regulating Neuronal Apoptosis

Advanced Science
Lactate plays diverse roles in brain pathophysiology, including ischemic stroke. Here, the role of lysine lactylation, an epigenetic modification of lactate, in cerebral ischemia is investigated.

Lactate Drives Pathological Browning of White Adipose Tissue to Aggravate Sepsis‐Associated Metabolic Disorders in a GPR81‐Dependent Manner

Advanced Science, EarlyView.
Sepsis‐triggered lactate accumulation induces pathological white adipose tissue browning. Lactate activates adipocyte GPR81 to sequentially upregulate CTRP6‐p38 signalling and UCP1 expression. This cascade exacerbates sepsis‐associated metabolic disorders.

From Metabolic Reprogramming to Lactylation: Targeting Dilemmas and Breakthrough Directions in Colorectal Cancer

Shengwu huaxue yu shengwu wuli jinzhan
Colorectal cancer (CRC) is characterized by persistently high incidence and mortality. Current therapies are limited by drug resistance and modest patient benefit, underscoring the urgent need for new perspectives rooted in tumor biology.

DUSP26 Regulated by YY1 Lactylation Couples Osteogenesis and Angiogenesis by Dephosphorylating PMPCB at Y141 and Activating Mitophagy in BMSCs

Advanced Science, EarlyView.
p300‐associated YY1 lactylation promotes DUSP26 expression in BMSCs. By regulating PMPCB phosphorylation and PINK1 processing, DUSP26 supports mitophagy, osteogenic differentiation, and pro‐angiogenic factor secretion. BMSC‐derived exosomes carrying a RUNX2 promoter‐driven DUSP26 plasmid favor osteogenic‐lineage transgene expression, partially ...

Lactate-binding protein DNMT3A in HRMECs promotes angiogenesis by upregulating VEGFA through HIF-1α lactylation

Genome Biology
Background Ocular neovascularization is a leading cause of blindness. Hypoxia is associated with retinal angiogenesis. Hypoxia results in lactate accumulation, which typically precedes protein lactylation, and this plays a crucial role in ocular ...

Metabolic Reprogramming-Driven Lactylation: Emerging Mechanisms Linking DNA Damage Repair and Chemoresistance in Cancer

Cells
Lactylation is an emerging lactate-derived post-translational modification that may link tumour metabolic reprogramming, epigenetic regulation and DNA damage repair. Enhanced glycolysis and lactate accumulation are common in many tumours, and lactate has

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

J Diabetes Investig
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.

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 ...
