A vector system encoding histone H3 mutants facilitates manipulations of the neuronal epigenome [PDF]
The differentiation of developmental cell lineages is associated with genome-wide modifications in histone H3 methylation. However, the causal role of histone H3 methylation in transcriptional regulation and cell differentiation has been difficult to ...

Stage-specific histone modification profiles reveal global transitions in the Xenopus embryonic epigenome. [PDF]
Vertebrate embryos are derived from a transitory pool of pluripotent cells. By the process of embryonic induction, these precursor cells are assigned to specific fates and differentiation programs.

Extracellular histone H3 facilitates ferroptosis in sepsis through ROS/JNK pathway
Introduction Previous evidence realized the critical role of histone in disease control. The anti‐inflammatory function of estradiol (E2) in sepsis has been documented.

Nanoarchaeal Origin of Histone H3? [PDF]
ABSTRACTNEQ288, one of two archaeal histones inNanoarchaeum equitans, has a unique four-residue insertion that closely resembles an insertion in the eukaryotic histone H3 lineage. NEQ288 bound DNA but did not compact DNA in vitro in the absence of NEQ348, the secondN. equitansarchaeal histone.

JAK2 Gets Histone H3 Rolling [PDF]
Activation of JAK2 is implicated in normal hematopoiesis as well as oncogenic transformation. A paper in the recent issue of Nature demonstrates that phosphorylation of histone H3 by JAK2 releases the transcriptional repressor HP1alpha from chromatin, resulting in gene transcription.

The inheritance of histone modifications depends upon the location in the chromosome in Saccharomyces cerevisiae. [PDF]
Histone modifications are important epigenetic features of chromatin that must be replicated faithfully. However, the molecular mechanisms required to duplicate and maintain histone modification patterns in chromatin remain to be determined.

Histone H3 serine 57 and lysine 56 interplay in transcription elongation and recovery from S-phase stress. [PDF]
BACKGROUND: Acetylation of lysine 56 of histone H3 plays an important role in the DNA damage response and it has been postulated to play an as yet undefined role in transcription, both in yeast and in higher eukaryotes.

Extracellular histones play a dual role—antimicrobial and cytotoxic—in host defense. In this study, we evaluated the antimicrobial and cytotoxic activities of histone H3 and identified the responsible molecular regions for these properties.

Dynamic Histone H3 Modifications Regulate Meiosis Initiation via Respiration
Meiosis is essential for genetic stability and diversity during sexual reproduction in most eukaryotes. Chromatin structure and gene expression are drastically changed during meiosis, and various histone modifications have been reported to participate in

Background Nuclear histone proteins are released into the extracellular space during sepsis and act as major mediators of death. However, circulating histone levels have not been precisely quantified.
