The replacement histone H2A.Z in a hyperacetylated form is a feature of active genes in the chicken [PDF]
, 2005 The replacement histone H2A.Z is variously reported as being linked to gene expression and preventing the spread of heterochromatin in yeast, or concentrated at heterochromatin in mammals.

Histone deacetylase 2-mediated deacetylation of the Ribonuclease 1 promoter in inflamed human endothelial cells [PDF]
, 2020 Endothelial cells (ECs) function as protective barrier to separate the blood from the surrounding tissue by conducting crucial roles in regulation and maintenance of vascular homeostasis, such as control of vessel permeability or coagulation.

FEBS Letters, EarlyView.The protonated form of butyrate, as well as other short‐chain fatty acids (SCFAs), is membrane permeable. In acidic extracellular environments, this can lead to intracellular accumulation of SCFAs and cytosolic acidification. This phenomenon will be particularly relevant in acidic environments such as the large intestine or tumor microenvironments ...

Dissecting the Hydrolytic Activities of Sarcoplasmic Reticulum ATPase in the Presence of Acetyl Phosphate [PDF]
J Biol Chem . 2002 Oct 11;277(41):38127-32Sarcoplasmic reticulum vesicles and purified Ca$^{2+}$-ATPase hydrolyze acetyl phosphate both in the presence and absence of Ca$^{2+}$. The Ca$^{2+}$-independent activity was fully sensitive to vanadate, insensitive to thapsigargin, and proceeded without accumulation of phosphorylated enzyme.

Controlled DNA compaction within chromatin: the tail-bridging effect [PDF]
, 2005 We study the mechanism underlying the attraction between nucleosomes, the fundamental packaging units of DNA inside the chromatin complex. We introduce a simple model of the nucleosome, the eight-tail colloid, consisting of a charged sphere with eight oppositely charged, flexible, grafted chains that represent the terminal histone tails. We demonstrate

ALCOHOL METABOLISM CONTRIBUTES TO BRAIN HISTONE ACETYLATION
Nature, 2019 Emerging evidence suggests that epigenetic regulation is dependent on metabolic state, and implicates specific metabolic factors in neural functions that drive behaviour1.

Evolutionary interplay between viruses and R‐loops
FEBS Letters, EarlyView.Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Correlation between ferroelectricity and torsional motion of acetyl groups in tris(4-acetylphenyl)amine observed by muon spin relaxation [PDF]
J. Appl. Phys. 137, 044102 (2025)It is demonstrated by muon spin relaxation and resonance experiments that the switchable spontaneous polarization of the organic ferroelectric compound tris(4-acetylphenyl)amine (TAPA) is governed by the local molecular dynamics of the acetyl group.

Dynamic chromatin: concerted nucleosome remodelling and acetylation [PDF]
, 2005 The flexibility of chromatin that enables translation of environmental cues into changes in genome utilisation, relies on a battery of enzymes able to modulate chromatin structure in a highly targeted and regulated manner.
