TranscriptomicsdKDM2 couples histone H2A ubiquitylation to histone H3 demethylation during Polycomb group silencing.
Transcription regulation involves enzyme-mediated changes in chromatin structure. Here, we describe a novel mode of histone crosstalk during gene silencing, in which histone H2A monoubiquitylation is coupled to the removal of histone H3 Lys 36 dimethylation (H3K36me2). This pathway was uncovered thr...

TranscriptomicsHistone acetylation and DNA demethylation of T-cells result in an anaplastic large cell lymphoma-like phenotype.
A characteristic feature of anaplastic large cell lymphoma (ALCL) is the significant reduction of the T-cell expression program despite its T-cell origin, a finding very similar to the loss of B-cell identity of classical Hodgkin lymphoma (cHL). Previously we demonstrated that epigenetic mechanisms ...

GenomicsHistone H3K4 Demethylation is Negatively Regulated by Histone H3 Acetylation in S. cerevisiae
Histone H3 lysine 4 tri-methylation (H3K4me3) is a hallmark of transcription initiation, but how H3K4me3 is demethylated during gene repression is poorly understood. Jhd2, a JmjC domain protein, was recently identified as the major H3K4me3 histone demethylase (HDM) in S. cerevisiae. While JHD2 is ...

ProteomicsDissection of TET1 catalytic and non-catalytic functions reveals DNA demethylation independent gene and ERV regulation
Surveillance of DNA methylation in mammals is critical for genome stability and epigenetic regulation. The discovery of the ten-eleven translocation (TET) proteins catalyzing the oxidation from 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC), 5-formylcytosine (5fC), and 5-carboxylcytosine (...

TranscriptomicsChIP-chip of siGFP- or siHOTAIR-treated foreskin fibroblasts with anti-H3K4me2, anti-LSD1 or anti-SUZ12 antibodies on HOX tiling array
Long intergenic noncoding RNAs (lincRNAs) regulate chromatin states and epigenetic inheritance. Here we show that the lincRNA HOTAIR serves as a scaffold for at least two distinct histone modification complexes. A 5’ domain of HOTAIR binds Polycomb Repressive Complex 2 (PRC2) while a 3’ domain of H...

TranscriptomicsReplication and active demethylation represent partially overlapping mechanisms for erasure of H3K4me3 in budding yeast
Histone modifications affect DNA-templated processes ranging from transcription to genomic replication. In this study, we examine the cell cycle dynamics of the trimethylated form of histone H3 lysine 4 (H3K4me3), a mark of active chromatin that is viewed as â??long-livedâ?? [1], and that is involve...

TranscriptomicsH3K4 demethylation by Jarid1a and Jarid1b contributes to retinoblastoma-mediated gene silencing during cellular senescence (expression)
Cellular senescence is a tumor-suppressive program that involves chromatin reorganization and specific changes in gene expression that trigger an irreversible cell-cycle arrest. We have examined the effect of suppressing the histone demethylases Jarid1a and Jarid1b on the senescence-associated gene ...
