ProteomicsLysine trimethylation in planktonic and pellicle modes of growth in Acinetobacter baumannii
An increasing number of studies have shown the importance of post-translational modifications (PTM) in bacterial physiology, especially during biofilm formation. Trimethylation of lysine residues is little studied due to lack of specific enrichment methods for this PTM. However, it may have a signif...

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...

ProteomicsHistone H4K20 Trimethylation is Decreased in Murine Models of Heart Disease
Heart disease is the leading cause of death in the developed world, and its comorbidities such as hypertension, diabetes, and heart failure are accompanied by major transcriptomic changes in the heart. During cardiac dysfunction, which leads to heart failure, there are global epigenetic alterations ...

GenomicsContext Dependency of Set1/COMPASS Mediated H3 Lysine 4 Trimethylation
The stimulation of trimethylation of histone H3 lysine 4 (H3K4) by H2B monoubiquitination (H2Bub) has been widely studied with multiple mechanisms proposed for this form of histone crosstalk. Cps35/Swd2 within COMPASS is considered to bridge these processes. However, a truncated form of Set1 (762-Se...

TranscriptomicsEZH1 and EZH2 Co-Govern Histone H3-K27 Trimethylation and Are Essential for Hair Follicle Homeostasis and Wound Repair
Polycomb protein group (PcG)-dependent trimethylation on H3-K27(H3K27me3) regulates identity of embryonic stem cells (SCs). How H3K27me3 governs adult SCs and tissue development is unclear. Here, we conditionally target H3-K27-methyltransferases Ezh2 and Ezh1 to address their roles in mouse skin hom...

TranscriptomicsMSL complex is attracted to genes marked by H3K36 trimethylation using a sequence-independent mechanism
In Drosophila, X chromosome dosage compensation requires the male-specific lethal (MSL) complex, which associates with actively transcribed genes on the single male X chromosome to upregulate transcription approximately 2-fold. We found that on the male X chromosome, or when MSL complex is ectopical...

TranscriptomicsEZH2-mediated H3K27 trimethylation mediates neurodegeneration in ataxia-telangiectasia
The symptoms of ataxia-telangiectasia (A-T) include a progressive neurodegeneration caused by ATM protein deficiency. We previously found that nuclear accumulation of histone deacetylase-4, HDAC4, contributes to this degeneration; we now report that increased histone H3K27 trimethylation (H3K27me3) ...

TranscriptomicsMll2 is required for H3K4 trimethylation on bivalent promoters in ES cells whereas Mll1 is redundant
Trimethylation of histone 3 lysine 4 (H3K4me3) at promoters of actively transcribed genes is a universal epigenetic mark and a key product of Trithorax-Group action. Here we show that Mll2, one of the six Set1/Trithorax-type H3K4 methyltransferases in mammals, is required for trimethylation of bival...
