Loss of H3K36 Methyltransferase SETD2 Impairs V(D)J Recombination during Lymphoid Development.

Project description:Repair of DNA double-stranded breaks (DSBs) during lymphocyte development is essential for V(D)J recombination and forms the basis of immunoglobulin variable region diversity. Understanding of this process in lymphogenesis has historically been centered on the study of RAG1/2 recombinases and a set of classical non-homologous end-joining factors. Much less has been reported regarding the role of chromatin modifications on this process. Here, we show a role for the non-redundant histone H3 lysine methyltransferase, Setd2, and its modification of lysine-36 trimethylation (H3K36me3), in the processing and joining of DNA ends during V(D)J recombination. Loss leads to mis-repair of Rag-induced DNA DSBs, especially when combined with loss of Atm kinase activity. Furthermore, loss reduces immune repertoire and a severe block in lymphogenesis as well as causes post-mitotic neuronal apoptosis. Together, these studies are suggestive of an important role of Setd2/H3K36me3 in these two mammalian developmental processes that are influenced by double-stranded break repair.

H3K36 methyltransferase NSD1 regulates chondrocyte differentiation for skeletal development and fracture repair.

Project description:Chondrocyte differentiation is a critical process for endochondral ossification, which is responsible for long bone development and fracture repair. Considerable progress has been made in understanding the transcriptional control of chondrocyte differentiation; however, epigenetic regulation of chondrocyte differentiation remains to be further studied. NSD1 is a H3K36 (histone H3 at lysine 36) methyltransferase. Here, we showed that mice with Nsd1 deficiency in Prx1+ mesenchymal progenitors but not in Col2+ chondrocytes showed impaired skeletal growth and fracture healing accompanied by decreased chondrogenic differentiation. Via combined RNA sequencing (RNA-seq) and chromatin immunoprecipitation sequencing (ChIP-seq) analysis, we identified sex determining region Y box 9 (Sox9), the key transcription factor of chondrogenic differentiation, as a functional target gene of NSD1. Mechanistically, NSD1 regulates Sox9 expression by modulating H3K36me1 and H3K36me2 levels in the Sox9 promoter region, constituting a novel epigenetic regulatory mechanism of chondrogenesis. Moreover, we found that NSD1 can directly activate the expression of hypoxia-inducible factor 1α (HIF1α), which plays a vital role in chondrogenic differentiation through its regulation of Sox9 expression. Collectively, the results of our study reveal crucial roles of NSD1 in regulating chondrogenic differentiation, skeletal growth, and fracture repair and expand our understanding of the function of epigenetic regulation in chondrogenesis and skeletal biology.

Structure, activity and function of the lysine methyltransferase SETD5.

Project description:SET domain-containing 5 (SETD5) is an uncharacterized member of the protein lysine methyltransferase family and is best known for its transcription machinery by methylating histone H3 on lysine 36 (H3K36). These well-characterized functions of SETD5 are transcription regulation, euchromatin formation, and RNA elongation and splicing. SETD5 is frequently mutated and hyperactive in both human neurodevelopmental disorders and cancer, and could be down-regulated by degradation through the ubiquitin-proteasome pathway, but the biochemical mechanisms underlying such dysregulation are rarely understood. Herein, we provide an update on the particularities of SETD5 enzymatic activity and substrate specificity concerning its biological importance, as well as its molecular and cellular impact on normal physiology and disease, with potential therapeutic options.

H3K36 methylation promotes longevity by enhancing transcriptional fidelity.

Project description:Epigenetic mechanisms, including histone post-translational modifications, control longevity in diverse organisms. Relatedly, loss of proper transcriptional regulation on a global scale is an emerging phenomenon of shortened life span, but the specific mechanisms linking these observations remain to be uncovered. Here, we describe a life span screen in Saccharomyces cerevisiae that is designed to identify amino acid residues of histones that regulate yeast replicative aging. Our results reveal that lack of sustained histone H3K36 methylation is commensurate with increased cryptic transcription in a subset of genes in old cells and with shorter life span. In contrast, deletion of the K36me2/3 demethylase Rph1 increases H3K36me3 within these genes, suppresses cryptic transcript initiation, and extends life span. We show that this aging phenomenon is conserved, as cryptic transcription also increases in old worms. We propose that epigenetic misregulation in aging cells leads to loss of transcriptional precision that is detrimental to life span, and, importantly, this acceleration in aging can be reversed by restoring transcriptional fidelity.
