(Submitter supplied) The antagonistic actions of Polycomb and Trithorax are responsible for proper cell fate determination in mammalian tissues. In the epidermis, a self-renewing epithelium, previous work has shown that release from Polycomb repression only partially explains differentiation gene activation. We now show that Trithorax is also a key regulator of epidermal differentiation, not only through activation of genes repressed by Polycomb in progenitor cells, but also through activation of genes independent of regulation by Polycomb. more...

(Submitter supplied) The COMPASS family catalyzes histone H3 lysine 4 (H3K4) methylation and its members are essential for regulating developmental gene expression. MLL2/COMPASS methylates H3K4 on many genes but only a subset lose expression upon MLL2 loss. To understand MLL2 -dependent transcriptional regulation, we performed a CRISPR screen in mouse embryonic stem cells (mESCs) and found that MLL2 protects developmental genes from repression by repelling PRC2 and DNA methylation machineries from these loci. more...

(Submitter supplied) The Ash2l protein is a member of KMT2 enzyme complexes, which catalyse the (tri-)methylation of lysine 4 of Histone H3. H3K4me3 is considered a marker of actively transcribed genes. We determined changes in gene expression as a consequence of a conditional loss of Ash2l in the bone marrow. The expression data from the bone marrows of mice with floxed Ash2l exon 4 alleles without (control) or with an Mx1-Cre transgene (KO) and treated with synthetic dsRNA to induce recombination and the loss of Ash2l protein expression were compared.

(Submitter supplied) The genomic mechanisms underlying progressive, irreversible cell lineage commitments and differentiation, which include large scale chromatin re-organization, transcription factor binding, and chromatin modifications, have been well defined. However, we know little about the chromatin changes during transitions between transient cell states such as cell migration. Here we demonstrate the formation of unique complements of typical enhancers and super-enhancers as human progenitor keratinocytes either differentiate or migrate. more...

(Submitter supplied) The process of differentiation is tightly controlled, and such complex coordination of gene expression requires many layers of regulation. One such mechanism of regulation occurs through distal genomic regions called enhancers, which are believed to act as concentrating sites for transcription factors, like GRHL3, and other regulators, forming loops to contact promoters and enhance transcription. Active enhancers have been shown to have high levels of H3K4me1 and H3K27ac modified nucleosomes, with low levels of H3K4me3, while poised developmental enhancers have been shown to have H3K27me3 in place of H3K27ac. more...
