PHF20 Readers Link Methylation of Histone H3K4 and p53 with H4K16 Acetylation

Cell Reports, 2016
PHF20 is a core component of the lysine acetyltransferase complex MOF (male absent on the first)-NSL (non-specific lethal) that generates the major epigenetic mark H4K16ac and is necessary for transcriptional regulation and DNA repair.

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.

β‐Elemene Rescues Radiation‐Induced Enteritis by Orchestrating a Host‐Microbiome Circuit That Fuels Epigenetic DNA Repair

Advanced Science, EarlyView.
This study elucidates that β‐elemene promotes cellular uptake of L. gasseri‐derived lactate by enhancing the membrane translocation of MCT1 in a CD147‐dependent manner. Intracellular lactate, through the lactylation of RBBP4 at the K26 site, recruits EP300 to the promoter regions of downstream genes (POLD1/POLD3), catalyzing H3K27ac modification.

The transcriptional cofactor MIER1-beta negatively regulates histone acetyltransferase activity of the CREB-binding protein

BMC Research Notes, 2008
Background Mier1 encodes a novel transcriptional regulator and was originally isolated as a fibroblast growth factor early response gene. Two major protein isoforms have been identified, MIER1α and β, which differ in their C-terminal sequence. Previously,

A Circuit of Mechanically Regulated Transcription Factors Balances Regenerative and Fibrotic Memory of Mesenchymal Stromal Cells

Advanced Science, EarlyView.
Producing MSCs on rigid culture substrates induces a scar‐making phenotype, jeapordizing therapeutic success. ‘Tissue‐soft’ surfaces prevent MSC fibrogenesis and preserve regenerative traits. An epigenetic network, driven by HOXA11 and SALL1, maintains ‘soft memory’ by keeping chromatin open in relaxed MSCs, promoting anti‐fibrotic programs.

Histone H3K23-specific acetylation by MORF is coupled to H3K14 acylation

Nature Communications, 2019
Acetylation of histone H3K23 has emerged as an essential posttranslational modification, yet this epigenetic mark remains poorly understood. Here, the authors identify the native MORF complex as a histone H3K23-specific acetyltransferase and show that ...

Targeting METTL3 Attenuates Thyroid Inflammatory Injury by Restoring Th17/Treg Balance through a YTHDC2‐m6A‐Dependent KDR/VEGFA Loop

Advanced Science, EarlyView.
METTL3‐mediated m6A modification stabilizes KDR/Kdr mRNA through YTHDC2, amplifying the VEGFA‐KDR feedback loop and disturbing Th17/Treg balance. This pathway promotes persistent inflammation and tissue damage in patients with AIT, and inhibiting the METTL3‐KDR axis effectively disrupts this circuit, alleviating thyroid tissue injury and disease ...

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 ...

NatD promotes lung cancer progression by preventing histone H4 serine phosphorylation to activate Slug expression

Nature Communications, 2017
NatD is an acetyltransferase responsible for N-α-terminal acetylation of the histone H4 and H2A and has been linked to cell growth. Here the authors show that NatD-mediated acetylation of histone H4 serine 1 competes with the phosphorylation by CK2α at ...

ANKS1B in the Nucleus Accumbens Controls Escalated Cocaine Self‐Administration via Regulating CBP‐FoxO3 Complex

Advanced Science, EarlyView.
ANKS1B in the nucleus accumbens plays a critical role in the transition from controlled to escalated cocaine intake. Mechanistically, ANKS1B interacts with CBP to epigenetically suppress FoxO3 through H3K27 acetylation. The ANKS1B‐CBP‐FoxO3 signaling cascade presents a novel theraputic target for the treatment of cocaine addiction.
