Description
The heart adapts to increased workload through hypertrophic growth of cardiomyocytes. Although beneficial when induced physiologically by exercise, pathological cues including hypertension cause reexpression of fetal genes and dysfunctional hypertrophy, with lasting consequences for cardiac health. We hypothesised that these differences are driven by changes in chromatin-encoded cellular memory. We generated genome-wide maps of transcription and of two stable epigenetic marks, H3K9me2 and H3K27me3, specifically in hypertrophied cardiomyocytes, by selectively flow-sorting their nuclei. This demonstrated a pervasive loss of euchromatic H3K9me2 specifically upon pathological but not physiological hypertrophy, derepressing genes associated with pathological hypertrophy. Levels of the H3K9 methyltransferases, G9a and GLP, were correspondingly reduced. Importantly, pharmacological or genetic inactivation of these enzymes was sufficient to induce pathological hypertrophy and the dedifferentiation associated with it. These findings suggest novel therapeutic opportunities by defining an epigenetic state of cardiomyocytes, acquired during maturation, which is required for maintaining cardiac health. Overall design: Examination of 2 different histone modifications and RNA expression in cardiomyocyte nuclei flow-sorted from hypertrophic rat hearts

The H3K9 dimethyltransferases EHMT1/2 protect against pathological cardiac hypertrophy.

Description
Processing of Immunoglobulin heavy chain (IgH) mRNA is a paradigm for competition between splicing and polyadenylation. In plasma cells pre-mRNA is polyadenylated mainly at the promoter-proximal secretory site while B-cells utilize a cryptic 5 splice site in the last secretory-specific exon; these are mutually exclusive events for all IgH pre-mRNAs. Transcription elongation factor ELL2, more abundant in plasma cells relative to B-cells, was down-modulated by overexpression of heterogenous ribonucleoprotein F, a condition which reduced production of secretory IgH mRNA. Transfection of B-cells with ELL2 and the IgH reporter showed an accelerated use of the secretory poly(A) site, positioned in competition with the splice to M1; a small interfering RNA to ELL2 reduced expression of IgH secretory mRNA. Co-transcription factors ELL1 and PC4 were ineffective at driving secretory-poly(A) site use. ELL2 had little effect on poly(A) site choice with reporters containing tandem-linked poly(A) sites. Shorter forms of ELL2 protein result from both internal initiation at M186 and protein processing. An alternative splicing reporter driven by IgH or non-Ig promoters revealed that ELL2 and its M186 initiated form were able to accelerate exon skipping. Therefore, ELL2 influences IgH pre-mRNA processing through facilitating skipping of the alternative splice to the membrane form.
Publication Title
Transcription elongation factor ELL2 directs immunoglobulin secretion in plasma cells by stimulating altered RNA processing.

Description
T lymphocytes are orchestrators of adaptive immunity. Nave T cells may differentiate into the Th1, Th2, Th17 or iTreg phenotype, depending on environmental co-stimulatory signals. In order to identify the genes and pathways involved in differentiation of Jurkat T cells towards Th1 and Th2 subtypes we performed comprehensive transcriptome analyses of Jurkat T cells stimulated with various stimuli an pathway inhibitors
