Histone lactylation as a driver of metabolic reprogramming and immune evasion

Medical Review
Abstract Lactate is the end product of glycolysis, and extensive research has shown that lactate participates in various pathophysiological processes. Along with associated hydrogen ions, lactate typically functions as an immunosuppressive negative factor and plays a crucial role in tumor metabolic reprogramming.

Lactylation‐Mediated HER2 Stabilization Promotes Trastuzumab Resistance in Gastric Cancer

Advanced Science, EarlyView.
Warburg effect‐derived lactate drives HER2 lactylation and trastuzumab resistance. Mechanistically, AARS1‐mediated lactylation stabilizes HER2 by inhibiting USP11‐dependent degradation and concurrently promotes HER2‐EGFR interaction. Importantly, inhibiting HER2 lactylation resensitizes gastric cancer cells to trastuzumab.

ACAT1‐Mediated SP1‐K694 Lactylation Promotes M1 Macrophage Polarization via TREM1 Transcription in COPD

Advanced Science, EarlyView.
Upon cigarette smoke exposure(CSE), LDHA expression is increased in lung macrophages, promoting the conversion of pyruvate to lactate and elevating the lactylation level of SP1 at the K694 site. This, in turn, enhances SP1 enrichment at the TREM1 promoter, increases TREM1 expression, promoted M1 macrophage polarization, and triggers the secretion of ...

AARS2‐SIRT5‐Driven DLD K445 Lactylation Promotes Cuproptosis Resistance in Glioblastoma Stem Cells

Advanced Science, EarlyView.
Lactylation of DLD at K445 by AARS2 suppresses PDH complex activity and reduces DLAT lipoylation, thereby conferring cuproptosis resistance in glioblastoma stem cells. SIRT5‐mediated delactylation restores PDH function and enhances cuproptosis sensitivity.

H4K12 Lactylation Regulates NDUFS7 to Drive Microglia Reverse Electron Transport in Spinal Cord Injury

Advanced Science, EarlyView.
Lactate accumulation after SCI promotes H4K12la lactylation, which upregulates NDUFS7, triggering mitochondrial RET and ROS, enforcing pro‐inflammatory microglial polarization. MM@mPTC, a biomimetic nanotherapeutic, degrades LDHA in activated microglia, reducing H4K12la lactylation and blocking RET, thus curbing ROS, fostering a reparative phenotype ...

Endothelial Cell‐Derived Lactate Triggers Bone Mesenchymal Stem Cell Histone Lactylation to Attenuate Osteoporosis

, 2023
Blood vessels play a role in osteogenesis and osteoporosis; however, the role of vascular metabolism in these processes remains unclear. The present study finds that ovariectomized mice exhibit reduced blood vessel density in the bone and reduced ...
