Journal ArticleDOI
Role of Histone H3 Lysine 27 Methylation in Polycomb-Group Silencing
Ru Cao,Liangjun Wang,Hengbin Wang,Li Xia,Hediye Erdjument-Bromage,Paul Tempst,Richard S. Jones,Yi Zhang +7 more
TL;DR: The purification and characterization of an EED-EZH2 complex, the human counterpart of the Drosophila ESC-E(Z) complex, is reported, and it is demonstrated that the complex specifically methylates nucleosomal histone H3 at lysine 27 (H3-K27).
Journal ArticleDOI
Double nicking by RNA-guided CRISPR Cas9 for enhanced genome editing specificity
F. Ann Ran,Patrick D. Hsu,Chie Yu Lin,Jonathan S. Gootenberg,Silvana Konermann,Alexandro E. Trevino,David A. Scott,Azusa Inoue,Shogo Matoba,Yi Zhang,Feng Zhang +10 more
TL;DR: In this paper, an approach that combines a Cas9 nickase mutant with paired guide RNAs to introduce targeted double-strand breaks is described. But the approach is limited to mouse zygotes.
Journal ArticleDOI
Tet proteins can convert 5-methylcytosine to 5-formylcytosine and 5-carboxylcytosine
Shinsuke Ito,Li Shen,Qing Dai,Susan C. Wu,Leonard B. Collins,James A. Swenberg,Chuan He,Yi Zhang +7 more
TL;DR: This study raises the possibility that DNA demethylation may occur through Tet-catalyzed oxidation followed by decarboxylation, and identifies two previously unknown cytosine derivatives in genomic DNA as the products of Tet proteins.
Journal ArticleDOI
Role of Tet proteins in 5mC to 5hmC conversion, ES-cell self-renewal and inner cell mass specification
Shinsuke Ito,Ana C. D’Alessio,Ana C. D’Alessio,Olena Taranova,Olena Taranova,Kwonho Hong,Kwonho Hong,Lawrence C. Sowers,Yi Zhang,Yi Zhang +9 more
TL;DR: It is demonstrated that all three mouse Tet proteins (Tet1, Tet2 and Tet3) can also catalyse a similar reaction, uncover the enzymatic activity of the Tet proteins, and demonstrate a role for Tet1 in ES cell maintenance and inner cell mass cell specification.
Journal ArticleDOI
Oncometabolite 2-Hydroxyglutarate Is a Competitive Inhibitor of α-Ketoglutarate-Dependent Dioxygenases
Wei Xu,Hui Yang,Ying Liu,Ying Yang,Ping Wang,Se Hee Kim,Shinsuke Ito,Chen Yang,Pu Wang,Meng Tao Xiao,Li Xia Liu,Wen Qing Jiang,Jing Liu,Jin Ye Zhang,Bin Wang,Stephen V. Frye,Yi Zhang,Yanhui Xu,Qun-Ying Lei,Kun-Liang Guan,Shimin Zhao,Yue Xiong +21 more
TL;DR: 2-HG is a competitive inhibitor of multiple α-KG-dependent dioxygenases, including histone demethylases and the TET family of 5-methlycytosine (5mC) hydroxylases, leading to genome-wide histone and DNA methylation alterations.
