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.

BRD8 Guards the Pluripotent State by Sensing and Maintaining Histone Acetylation

Advanced Science
Epigenetic control of cell fates is a critical determinant to maintain cell type stability and permit differentiation during embryonic development. However, the epigenetic control mechanisms are not well understood.

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 ...

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.

A 6-alkylsalicylate histone acetyltransferase inhibitor inhibits histone acetylation and pro-inflammatory gene expression in murine precision-cut lung slices

Pulmonary Pharmacology & Therapeutics, 2017
Lysine acetylations are post-translational modifications of cellular proteins, that are crucial in the regulation of many cellular processes. Lysine acetylations on histone proteins are part of the epigenetic code regulating gene transcription and are ...

DDX3x Regulates NINJ1 Transcription via Histone Lactylation in Sepsis Associated‐Acute Kidney Injury

Advanced Science, EarlyView.
This study identifies a potential therapeutic approach for sepsis‐associated acute kidney injury (SA‐AKI). We found that during SA‐AKI, reduced expression of DDX3x in renal tubular epithelial cells mediates histone delactylation, which in turn upregulates NINJ1 transcription and triggers tubular cell death. Conversely, Odetiglucan confers protection by

Glucose and Glutamine Deprivation Promotes Breast Cancer Lung Metastasis via BRD4‐Dependent Enhancer Activation

Advanced Science, EarlyView.
To model a nutrient‐restricted tumor microenvironment, breast cancer cells were adapted to low glucose and glutamine levels. In the adapted cells, BRD4‐driven enhancer activation increases pro‐invasive EDN1 expression, facilitated by ATF3/c‐JUN and reinforced by enhancer RNA.

Methamphetamine causes differential alterations in gene expression and patterns of histone acetylation/hypoacetylation in the rat nucleus accumbens. [PDF]

PLoS ONE, 2012
Methamphetamine (METH) addiction is associated with several neuropsychiatric symptoms. Little is known about the effects of METH on gene expression and epigenetic modifications in the rat nucleus accumbens (NAC).

Tetrahymena histone acetyltransferase A: a homolog to yeast Gcn5p linking histone acetylation to gene activation.

Cell, 1996
We report the cloning of a transcription-associated histone acetyltransferase type A(HAT A). This Tetrahymena enzyme is strikingly homologous to the yeast protein Gcn5, a putative transcriptional adaptor, and we demonstrate that recombinant Gcn5p ...
