MetabolomicsSodium Butyrate mediates Histone Crotonylation and Alleviated Neonatal Rats Hypoxic-Ischemic Brain Injury Through Gut-Brain Axis (untargeted fecal metabolomics)

Neonatal hypoxic-ischemic encephalopathy (HIE) refers to nervous system damage caused by perinatal hypoxia, which is the major cause of long-term neuro-developmental disorders in surviving infants. However, the mechanisms still require further investigation. In this study, we found that the butan...

GenomicsIdentification of 67 histone marks and histone lysine crotonylation as a new type of histone modification
We report the identification of 67 previously undescribed histone modifications, increasing the current number of known histone marks by about 70%. We further investigated one of the marks, lysine crotonylation (Kcr), confirming that it represents an evolutionarily-conserved histone posttranslationa...

ProteomicsQuantitative histone mass spectrometry identifies elevated histone H3 lysine 27 trimethylation in melanoma
Normal cell growth is characterized by a regulated epigenetic program that drives cellular activities such as gene transcription, DNA replication and DNA damage repair. Perturbation of this epigenetic program can lead to events such as mis-regulation of gene transcription and diseases such as cancer...

ProteomicsTwo DOT1 enzymes cooperatively mediate efficient ubiquitin-independent histone H3 lysine 76 tri-methylation in kinetoplastids
In higher eukaryotes, a single DOT1 histone H3 lysine 79 (H3K79) methyltransferase processively produces H3K79me2/me3 from me0 through histone H2B mono-ubiquitin interaction. The early-branched kinetoplastid Trypanosoma brucei harbors the essential H3K76 di-methyltransferase DOT1A and the non-essent...

GenomicsCpG islands recruit a histone H3 lysine 36 demethylase [Illumina sequencing data]
Eukaryotic gene expression profiles are largely defined by transcription factors that recognize specific DNA sequences in gene regulatory regions and impact RNA polymerase recruitment and transcription. In addition to specific core promoter regulatory elements, up to 70% of genes in higher eukaryote...

TranscriptomicsThe Histone H3 Lysine 9 Methyltransferases G9a and GLP Regulate Polycomb Repressive Complex 2-Mediated Gene Silencing [RNA-Seq]
G9a/GLP and Polycomb Repressive Complex 2 (PRC2) are two major epigenetic silencing machineries, which in particular methylate histone H3 on lysines 9 and 27 (H3K9 and H3K27), respectively. Although evidence of a crosstalk between H3K9 and H3K27 methylations has started to emerge, their actual inter...

GenomicsGenome-wide map of lysine specific demethylase 1 (LSD1) in mouse embryonic stem cells.
We report the identification of LSD1 binding genomic regions in mouse embryonic stem cells (ESC) by high throughput sequencing. By obtaining over 10 million 36 bp reads of sequence from each chromatin immunoprecipitated DNA, we generated genome-wide maps for LSD1 and histone H3 dimethylated on lysin...
