MetabolomicsCDK4-driven ketogenesis rewires histone modification to promote leukemia

How ketogenic metabolites affect tumorigenesis, and whether ketone metabolism becomes deregulated in cancer cells, remain incompletely understood. Using T-cell acute lymphoblastic leukemia (T-ALL) as a model, we demonstrate that the ketone body β-hydroxybutyrate (BHB) is elevated in cancer cells ...

MetabolomicsHistone serotonylation promotes pancreatic cancer development via lipid metabolism remodeling

Neurotransmitter serotonin (5-hydroxytryptamine [5-HT]) has emerged to play parallel roles in both neurobiology and oncology. Apart from receptor-mediated signaling transduction pattern, serotonin can be covalently integrated into histone (the post-translational modification known as histone sero...

ProteomicsPathology tissue-quantitative mass spectrometry analysis to profile histone post-translational modification patterns in patient samples
Histone post-translational modifications (hPTMs) generate a complex combinatorial code that has been implicated with various pathologies, including cancer. Dissecting such a code in physiological and diseased states may be exploited for epigenetic biomarker discovery, but hPTM analysis in clinical s...

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...

GenomicsH3K36ac is an evolutionary conserved histone modification that marks active genes in plants
In eukaryotic cells, DNA is tightly packed in the nucleus in chromatin which has histones as its main protein component. Histones are subject to a large number of distinct post-translational modifications, whose sequential or combinatorial action affects genome function. Here, we report the identifi...

GenomicsGenome-wide analysis of histone modifications in human endometrial stromal cells [ChIP-Seq]
Dramatic changes of gene expressions are known to occur in human endometrial stromal cells (ESC) during decidualization. The changes in gene expression are associated with changes of chromatin structure, which are regulated by epigenetic mechanisms such as histone modifications. Here, we investiga...

ProteomicsEnvironmental Conditions Elicit a Slow but Enduring Response of Histone Post-Translational Modifications in Mozambique Tilapia
Histone post-translational modifications (PTMs) are epigenetic marks that operate within the central dogma of molecular biology: upon an environmental stimulus, the histone PTMs surrounding DNA can be changed in a way that modifies gene expression, and, therefore, the abundance and composition of RN...
