MetabolomicsSOX2 Drives Esophageal Squamous Carcinoma by Reprogramming Lipid Metabolism and Histone Acetylation Landscape

SOX2 is not only a pioneer transcription factor with critical roles in stem cell function and cell reprogramming but also a potent oncogene for a multitude of squamous cancers. How SOX2 exerts a potent oncogenic activity in squamous lineage is largely unknown. Here we uncovered SOX2 a p...

GenomicsAF9 Links Histone Acetylation to DOT1L-Mediated H3K79 Methylation
The recognition of modified histones by “reader” proteins constitutes a key mechanism regulating gene expression in the chromatin context. Compared with the great variety of readers for histone methylation, few protein modules that recognize histone acetylation are known. Here we show that the evolu...

GenomicsHistone acetylation regulates intracellular pH
Differences in global levels of histone acetylation occur in normal and cancer cells, although the reason cells regulate these levels has remained unclear. Here we demonstrate a role for histone acetylation in regulating intracellular pH (pHi). As pHi decreases, histones are globally deacetylated by...

ProteomicsA Chemical Acetylation based Mass Spectrometry Platform for Histone Profiling
Here we present a strategy for the identification and quantitation of histone methylation that utilizes nondeuterated acetic anhydride to fully acetylate all free lysine residues prior to digestion with trypsin and analysis by LC-MS/MS.

ProteomicsLinking acetyl-CoA labelling and histone acetylation dynamics for accurate determination of acetylation rates via ordinary differential equations
To study complex biological systems, multi-omics methods have become an important tool. They integrate data from multiple biological layers, such as the metabolome and the proteome, to gain better insights of the processes happening. However, challenges remain both in sample preparation for measurem...

GenomicsHistone H3K4 Demethylation is Negatively Regulated by Histone H3 Acetylation in S. cerevisiae
Histone H3 lysine 4 tri-methylation (H3K4me3) is a hallmark of transcription initiation, but how H3K4me3 is demethylated during gene repression is poorly understood. Jhd2, a JmjC domain protein, was recently identified as the major H3K4me3 histone demethylase (HDM) in S. cerevisiae. While JHD2 is ...

ProteomicsLipids reprogram cellular metabolism to become a major carbon source for histone acetylation.
From McDonnell et. al. Cell Reports 2016: Cells integrate nutrient sensing and metabolism to coordinate proper cellular responses to a particular nutrient source. For example, glucose drives a gene expression program characterized by activating genes involved in its metabolism, in part, by increasi...

TranscriptomicsComparative histone modification profiling revealed developmentally regulated acetylation on upstream promoters of C4 genes and potential C4 regulators
We analysed genome-wide histone H3 lysine 4 trimethylation and histone H3 lysine 9 acetylation, two modifications typically associated with active genes, in meristematic cells at the base and expanding cells in the maturing zone of the maize (Zea mays) leaf. These data were compared to transcript le...
