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.

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).

Arabidopsis SWR1-associated protein methyl-CpG-binding domain 9 is required for histone H2A.Z deposition. [PDF]

, 2019
Deposition of the histone variant H2A.Z by the SWI2/SNF2-Related 1 chromatin remodeling complex (SWR1-C) is important for gene regulation in eukaryotes, but the composition of the Arabidopsis SWR1-C has not been thoroughly characterized.

Different Behavioral Experiences Produce Distinctive Parallel Changes in, and Correlate With, Frontal Cortex and Hippocampal Global Post-translational Histone Levels. [PDF]

, 2018
While it is clear that behavioral experience modulates epigenetic profiles, it is less evident how the nature of that experience influences outcomes and whether epigenetic/genetic biomarkers could be extracted to classify different types of behavioral ...

Autoacetylation of the Histone Acetyltransferase Rtt109 [PDF]

Journal of Biological Chemistry, 2011
Rtt109 is a yeast histone acetyltransferase (HAT) that associates with histone chaperones Asf1 and Vps75 to acetylate H3K56, H3K9, and H3K27 and is important in DNA replication and maintaining genomic integrity. Recently, mass spectrometry and structural studies of Rtt109 have shown that active site residue Lys-290 is acetylated.

DNMT2‐m5C‐ACLY Axis Promotes Lenvatinib Resistance in Hepatocellular Carcinoma Through Histone Acetylation‐Mediated Notch Pathway

Advanced Science, EarlyView.
Lenvatinib resistance poses a major challenge in advanced hepatocellular carcinoma (HCC). This study reveals that DNMT2 upregulation is a key driver, which stabilizes ACLY mRNA via m5C modification and activates the Notch signaling pathway. Crucially, combining ACLY inhibitors with lenvatinib overcomes resistance and suppresses tumors, offering a ...

Acetylation Regulates ACSL4 Degradation Through Chaperone‐Mediated Autophagy to Alleviate Intervertebral Disc Degeneration

Advanced Science, EarlyView.
Intervertebral disc degeneration is triggered by ACSL4 accumulation‐mediated ferroptosis of nucleus pulposus cells due to CMA dysfunction. KAT2B promotes ACSL4 degradation via CMA through acetylation. AAV‐mediated LAMP2A delivery or engineered exosomes rescue nucleus pulposus cell senescence and disc degeneration.

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 ...

A latent ability to persist: differentiation in Toxoplasma gondii [PDF]

, 2018
A critical factor in the transmission and pathogenesis of Toxoplasma gondii is the ability to convert from an acute disease-causing, proliferative stage (tachyzoite), to a chronic, dormant stage (bradyzoite).
