Inhibition of Histone Lysine Acetyltransferases by Coenzyme A Analogs

Molecules
Histone lysine acetylation is a widespread posttranslational modification, essential for vital functions in eukaryotic organisms. Histone lysine acetyltransferases (KATs) employ acetyl-coenzyme A as a universal acetyl donor for acetylation of lysine ...

An Epigenetic Fate Converter Based on Nuclei‐Targeting Lipid Nanoparticles Drives Neuronal Programming of Stem Cells for Spinal Cord Repair

Advanced Functional Materials, EarlyView.
Schematic illustration of LNP‐MPG nuclei‐targeting delivery of HMW‐FGF2 promoting histone acetylation to regulate the fate of DPSCs and treat spinal cord injury. LNPs components include pHMW‐FGF2 plasmid, DSPC, Dlin‐MC3‐DMA, cholesterol, and PEG2000, and are modified with MPG to form HMW‐FGF2@LNP‐MPG (HLM). HLM nuclei‐targets DPSCs to deliver HMW‐FGF2,

Histone Modifications and Other Facets of Epigenetic Regulation in Trypanosomatids: Leaving Their Mark

mBio, 2020
Histone posttranslational modifications (PTMs) modulate several eukaryotic cellular processes, including transcription, replication, and repair. Vast arrays of modifications have been identified in conventional eukaryotes over the last 20 to 25 years ...

Phosphorylation‐Facilitated CKB Lactylation At K11 By GCN5 Enhances Creatine Kinase Activity and Mitigates Neuronal Damage After Cerebral Ischemia‐Reperfusion

Advanced Science, EarlyView.
This study uncovers hierarchical coordination between K11 lactylation and S199 phosphorylation of CKB in cerebral ischemia‐reperfusion injury. Such dual modifications potentiate CKB enzymatic function, remodel energy metabolism, alleviate oxidative stress and neuronal damage, and represent a viable therapeutic target for stroke treatment.

Hyperacetylated histone H4 is a source of carbon contributing to lipid synthesis

The EMBO Journal
Histone modifications commonly integrate environmental cues with cellular metabolic outputs by affecting gene expression. However, chromatin modifications such as acetylation do not always correlate with transcription, pointing towards an alternative ...

Catalytic activation of histone acetyltransferase Rtt109 by a histone chaperone [PDF]

Proceedings of the National Academy of Sciences, 2010
Most histone acetyltransferases (HATs) function as multisubunit complexes in which accessory proteins regulate substrate specificity and catalytic efficiency. Rtt109 is a particularly interesting example of a HAT whose specificity and catalytic activity require association with either of two histone chaperones, Vps75 or Asf1.

ANXA2+ Small Extracellular Vesicles Drive Chemoresistance in Anaplastic Thyroid Cancer by Promoting XRCC5 Lactylation and Enhancing Non‐Homologous End‐Joining Repair

Advanced Science, EarlyView.
ANXA2+ sEVs promote cisplatin resistance in ATC by stabilizing the SRC/LDHA interaction, increasing LDHA phosphorylation and activity, and lactate production. Elevated lactate levels promote KAT5‐mediated lactylation of XRCC5 at lysine 265, enhancing its binding to XRCC6.
