MetabolomicsDietary Glutamine Supplementation Mitigates Age-Associated Cardiac Decline by Restricting H3K27me3

Epigenetic alterations are central drivers of cardiovascular aging, with histone modifications regulating gene expression through chromatin remodeling and changes in DNA accessibility. However, the mechanisms underlying these epigenetic shifts in the aging heart remain poorly defined. Here, we id...

TranscriptomicsIdentification and characterization of two novel primate-specific histone H3 variants H3.X and H3.Y
Nucleosomal incorporation of specialized histone variants is an important mechanism to generate different functional chromatin states. Here we report the identification and characterization of two novel primate-specific histone H3 variants, H3.X and H3.Y. Their mRNAs are found in certain human cell ...

TranscriptomicsGenome-wide analysis of histone H3.1 and H3.3 variants in Arabidopsis thaliana
Nucleosomes package eukaryotic DNA and are composed of four different histone proteins, H3, H4, H2A and H2B. Histone H3 has two main variants, H3.1 and H3.3, which show different genomic localization patterns in animals. We profiled H3.1 and H3.3 variants in the genome of the plant Arabidopsis thali...

ProteomicsMind Your Spectra: Points to be Aware of when Validating the Identification of Isobaric Histone Peptidoforms
Mass spectrometry (MS) is now well recognized as a powerful technique to identify and quantify post-translational modifications (PTMs), overcoming many of the limitations of antibody-based methods. Histones, which play a central role in all DNA-templated processes, are regulated by a wealth of dynam...

GenomicsMapping of somatic linker histone H1 variants in T47D-MTVL cells
At least six histone H1 variants exist in mammalian somatic cells that bind to the linker DNA and stabilize the nucleosome particle contributing to higher order chromatin compaction. In addition, H1 seems to be involved in the active regulation of gene expression. It is not well known whether the di...

GenomicsDistribution of active (H3K4me1, H3K4me3, H3K27ac) and inactive (H3K9me3, H3K27me3) histone PTMs in WT and HIRA KO HeLa cells
We profiled the enrichment of active (H3K4me1, H3K4me3, H3K27ac) and inactive (H3K9me3, H3K27me3) histone PTMs in cells that are wild-type (WT) or knock-out (KO) for the H3.3-specific chaperone HIRA. We performed native ChIP-seq following MNase digestion to isolate nucleosomes in H3.1-SNAP and H3.3-...

GenomicsDynamic Deposition of the Histone H3.3 Variant Accompanies Developmental Remodeling of Arabidopsis Transcriptome (ChIP-Seq)
In animals, replication coupled histone H3.1 can be distinguished from replication independent histone H3.3. H3.3 variants are enriched at active genes and their promoters. Furthermore, H3.3 is specifically incorporated upon gene activation. Histone H3 variants evolved independently in plants and an...

ProteomicsH2A.Z histone variants facilitate HDACi-dependent removal of H3.3K27M mutant protein in paediatric high-grade glioma cells
Diffuse intrinsic pontine gliomas (DIPG) are a deadly paediatric brain tumours, non-resectable due to brainstem localisation and diffusive growth. Patients with DIPG have a dismal prognosis of 9-12 months of survival with no effective therapy. Over 80% of DIPGs harbour a mutation in histone 3 (H3.3 ...
