Cancer Center Grand Rounds Yi Zhang, PhD Investigator, Howard Hughes Medical Institute Fred Rosen Professor of Pediatrics, Boston Children’s Hospital Professor of Genetics, Harvard Medical School “Role of H3K27me3-Mediated Genomic Imprinting in Development & SCNT Reprogramming” Mammalian sperm and oocytes have different epigenetic landscapes and are organized in different fashion. Following fertilization, the initially distinct parental epigenomes become largely equalized with the exception of certain loci including imprinting control regions (ICRs). How parental chromatin becomes equalized and how ICRs escape from this reprogramming is largely unknown. Based on allelic chromatin accessibility and gene expression analyses, we identified a DNA methylation-independent, H3K27me3-dependent imprinting mechanism. We demonstrate H3K27me3-mediated genomic imprinting plays an important role in imprinted X-chromosome inactivation, placenta development, and somatic cell nuclear transfer reprogramming.

Study Identifies a Protein Complex Possibly Crucial for Triggering Embryo Development 6 January 2010
Study identifies a protein complex possibly crucial for triggering embryo development 6 January 2010 modifications that often prevent them from curbing the proliferation of cancer cells. The discovery may also have implications for stem cell research by providing a tool to quickly reprogram adult cells to possess the same attributes as embryonic stem cells, but without the ethical or safety issues of cells currently used for such studies. The results of the study appear on- line in the Jan. 6, 2010 issue of the journal Nature. "The implications of such research have always been clear, and that is why for years researchers have tried to identify a factor responsible for erasing these epigenetic markers," said senior This is a fertilized human egg, prior to division.

IFN-g–producing Th1 CD4+ T cells mediate the immune destruction of hematopoietic cells, and they are central to the pathogenesis. However, the molecular events that control the development of BM-destructive Th1 cells remain largely unknown. Ezh2 is a chromatin-modifying enzyme that regulates multiple cellular processes primarily by silencing gene expression. We recently reported that Ezh2 is crucial for inflammatory T cell responses after allogeneic BM transplantation. To elucidate whether Ezh2 mediates pathogenic Th1 responses in AA and the mechanism of Ezh2 action in regulating Th1 cells, we studied the effects of Ezh2 inhibition in CD4+ T cells using a mouse model of human AA. Conditionally deleting Ezh2 in mature T cells dramatically reduced the production of BM- destructive Th1 cells in vivo, decreased BM-infiltrating Th1 cells, and rescued mice from BM failure. Ezh2 inhibition resulted in significant decrease in the expression of Tbx21 and Stat4, which encode transcription factors T-bet and STAT4, respectively. Introduction of T-bet but not STAT4 into Ezh2-deficient T cells fully rescued their differentiation into Th1 cells mediating AA. Ezh2 bound to the Tbx21 promoter in Th1 cells and directly activated Tbx21 transcription.

Dependent Autosomal and X Chromosome Imprinting
REVIEWS Maternal H3K27me3- dependent autosomal and X chromosome imprinting Zhiyuan Chen 1,2,3 and Yi Zhang 1,2,3,4,5 ✉ Abstract | Genomic imprinting and X- chromosome inactivation (XCI) are classic epigenetic phenomena that involve transcriptional silencing of one parental allele. Germline- derived differential DNA methylation is the best-studied epigenetic mark that initiates imprinting, but evidence indicates that other mechanisms exist. Recent studies have revealed that maternal trimethylation of H3 on lysine 27 (H3K27me3) mediates autosomal maternal allele-specific gene silencing and has an important role in imprinted XCI through repression of maternalXist . Furthermore, loss of H3K27me3-mediated imprinting contributes to the developmental defects observed in cloned embryos. This novel maternal H3K27me3- mediated non-canonical imprinting mechanism further emphasizes the important role of parental chromatin in development and could provide the basis for improving the efficiency of embryo cloning. 10 Pronuclear transfer Most autosomal genes in diploid cells are transcribed found to be critical for imprinted gene expression .

Set9, a Novel Histone H3 Methyltransferase That Facilitates Transcription by Precluding Histone Tail Modifications Required for Heterochromatin Formation
Downloaded from genesdev.cshlp.org on October 1, 2021 - Published by Cold Spring Harbor Laboratory Press Set9, a novel histone H3 methyltransferase that facilitates transcription by precluding histone tail modifications required for heterochromatin formation Kenichi Nishioka,1 Sergei Chuikov,1 Kavitha Sarma,1 Hediye Erdjument-Bromage,2 C. David Allis,3 Paul Tempst,2 and Danny Reinberg1,4 1Howard Hughes Medical Institute, Division of Nucleic Acids Enzymology, Department of Biochemistry, University of Medicine and Dentistry of New Jersey, Robert Wood Johnson Medical School, Piscataway, New Jersey 08854, USA; 2Molecular Biology Program, Memorial Sloan Kettering Cancer Center, New York, New York 10021, USA; 3University of Virginia, Department of Biochemistry & Molecular Genetics, University of Virginia Health System, Charlottesville, Virginia 22908-0733, USA A novel histone methyltransferase, termed Set9, was isolated from human cells. Set9 contains a SET domain, but lacks the pre- and post-SET domains. Set9 methylates specifically lysine 4 (K4) of histone H3 (H3-K4) and potentiates transcription activation. The histone H3 tail interacts specifically with the histone deacetylase NuRD complex. Methylation of histone H3-K4 by Set9 precludes the association of NuRD with the H3 tail. Moreover, methylation of H3-K4 impairs Suv39h1-mediated methylation at K9 of H3 (H3-K9). The interplay between the Set9 and Suv39h1 histone methyltransferases is specific, as the methylation of H3-K9 by the histone methyltransferase G9a was not affected by Set9 methylation of H3-K4. Our studies suggest that Set9-mediated methylation of H3-K4 functions in transcription activation by competing with histone deacetylases and by precluding H3-K9 methylation by Suv39h1.
