Histone-like TAFs within the PCAF Histone Acetylase Complex [PDF]

, 1998
PCAF histone acetylase plays a role in regulation of transcription, cell cycle progression, and differentiation. Here, we show that PCAF is found in a complex consisting of more than 20 distinct polypeptides.

DNA‐PKcs‐Driven YAP1 Phosphorylation and Nuclear Translocation: a Key Regulator of Ferroptosis in Hyperglycemia‐Induced Cardiac Dysfunction in Type 1 Diabetes

Advanced Science, EarlyView.
In the context of chronic hyperglycemia, a DDR is initiated, leading to the pathological activation of DNA‐PKcs in the diabetic heart. This activated DNA‐PKcs directly interacts with and phosphorylates YAP1 at Thr226, thereby increasing the nuclear expression of YAP1.

Suv39h-Mediated Histone H3 Lysine 9 Methylation Directs DNA Methylation to Major Satellite Repeats at Pericentric Heterochromatin [PDF]

, 2003
Background: Histone H3 lysine 9 (H3-K9) methylation and DNA methylation are characteristic hallmarks of mammalian heterochromatin. H3-K9 methylation was recently shown to be a prerequisite for DNA methylation in Neurospora crassa and Arabidopsis thaliana.

Histone Lactylation Antagonizes Senescence and Skeletal Muscle Aging by Modulating Aging‐Related Pathways

Advanced Science, EarlyView.
This study reveals histone lactylation as a metabolic‐epigenetic regulator countering cellular senescence and skeletal muscle aging. Reduced lactylation impairs cell cycle, DNA repair and proteostasis pathways, while exercise restores glycolytic activity and lactylation levels, preserving muscle function.

Causal role of histone acetylations in enhancer function [PDF]

, 2016
Enhancers control development and cellular function by spatiotemporal regulation of gene expression. Co-occurrence of acetylation of histone H3 at lysine 27 (H3K27ac) and mono methylation of histone H3 at lysine 4 (H3K4me1) has been widely used for ...

The Nuclear Localization of ACLY Guards Early Embryo Development Through Recruiting P300 and HAT1 to Promote Histone Acetylation and Transcription

Advanced Science, EarlyView.
ACLY is vital for early embryo development. IGF‐1 activates AKT to phosphorylate ACLY, driving its nuclear localization and recruitment of HATs (P300/HAT1), boosting acetyl‐CoA production and histone acetylation for transcriptional activation. Conversely, ACLY deficiency (via knockdown, knockout, or AKT inhibition) reduces nuclear acetyl‐CoA, disrupts ...

Mitotic phosphorylation of histone H3 threonine 80 [PDF]

Cell Cycle, 2013
The onset and regulation of mitosis is dependent on phosphorylation of a wide array of proteins. Among the proteins that are phosphorylated during mitosis is histone H3, which is heavily phosphorylated on its N-terminal tail. In addition, large-scale mass spectrometry screens have revealed that histone H3 phosphorylation can occur at multiple sites ...

Histone modifications influence the action of Snf2 family remodelling enzymes by different mechanisms [PDF]

, 2007
Alteration of chromatin structure by chromatin modifying and remodelling activities is a key stage in the regulation of many nuclear processes. These activities are frequently interlinked, and many chromatin remodelling enzymes contain motifs that ...

piR‐RCC Suppresses Renal Cell Carcinoma Progression by Facilitating YBX‐1 Cytoplasm Localization

Advanced Science, EarlyView.
PIWI‐interacting RNAs (piRNAs), a novel category of small non‐coding RNAs, have been implicated in the development of various diseases. This study explores the tumor‐suppressive mechanism of a downregulated piRNA (designated piR‐RCC) in renal cell carcinoma (RCC), and provides a delivery strategy targeting RCC tumor by constructing a cell membrane ...

Acute (binge) administration of ethanol causes histone H3 phosphorylation at SER-10, SER-28 & gene expression in rat liver in vivo [abstract] [PDF]

, 2010
Epigenetic histone modification is emerging as a critical player in the cellular actions of ethanol. In this study we have examined the effect of ethanol on histone H3 phosphorylation in vivo using an acute model. Twelve week old male Sprague Dawley rats
