TranscriptomicsEZH2 Inhibition as a Therapeutic Strategy for Lymphoma with EZH2 Activating Mutations
This SuperSeries is composed of the following subset Series: GSE40970: ChIP-seq analysis of H3K27me3 histone modification in EZH2 mutant and wild type DLBCL cell lines GSE40971: Gene expression profiling of EZH2 mutant and wild type DLBCL cell lines treated with EZH2 inhibitor GSE41239: Gene express...

TranscriptomicsGene expression profiling of two DLBCL cell lines upon shRNA mediated knockdown of EZH2
We studied transcriptional changes by Affymetrix human microarrays in 2 DLBCL cell lines as a result of shRNA mediated knockdown of EZH2. In eukaryotes, epigenetic post-translational modification of histones is critical for regulation of chromatin structure and gene expression. EZH2 is the catalytic...

TranscriptomicsEZH2 is required for germinal center formation and somatic EZH2 mutations promote lymphoid transformation
The EZH2 histone methyltransferase is highly expressed in germinal center (GC) B-cells and targeted by somatic mutations in B-cell lymphomas. Here we find that EZH2 deletion or pharmacologic inhibition suppresses GC formation and functions in mice. EZH2 represses proliferation checkpoint genes and h...

TranscriptomicsDual role of EZH2 on megakaryocyte differentiation, analysis at different stages of maturation at day 9 of culture
EZH2, the enzymatic component of PRC2, has been identified as a key factor in hematopoiesis. EZH2 loss of function mutations have been found in myeloproliferative neoplasms, more particularly in myelofibrosis, but the precise function of EZH2 in megakaryopoiesis is not fully delineated. Here, we sho...

TranscriptomicsGene expression profiling of EZH2 mutant and wild type DLBCL cell lines treated with EZH2 inhibitor
We studied transcriptional changes by Affymetrix human microarrays in DLBCL cell lines as a result of treatment with GSK126, a potent, highly-selective, SAM-competitive, small molecule inhibitor of EZH2 In eukaryotes, epigenetic post-translational modification of histones is critical for regulation ...

TranscriptomicsEpigenetic repression of cardiac progenitor gene expression by Ezh2 is required for postnatal cardiac homeostasis
Adult-onset diseases can be associated with in utero events, but mechanisms for such temporally distant dysregulation of organ function remain unknown. The polycomb histone methyltransferase, Ezh2, stabilizes transcription by depositing repressive histone marks during development that persist into ...

TranscriptomicsGene expression profiles of EZH2 knockdown
Enhancer of Zeste Homolog 2 (EZH2) is a histone methyltransferase that catalyzes the trimethylation of histone H3 lysine 27 (H3K27me3). EZH2 expression is significantly upregulated in MPNST. In our study, we investigated the function of EZH2 and the molecular mechanisms that are regulated by EZH2 in...

GenomicsChIP-seq analysis of H3K27me3 histone modification in EZH2 mutant and wild type DLBCL cell lines
In eukaryotes, epigenetic post-translational modification of histones is critical for regulation of chromatin structure and gene expression. EZH2 is the catalytic subunit of the Polycomb Repressive Complex 2 (PRC2) and is responsible for repressing target gene expression through methylation of histo...

TranscriptomicsExpression data from EZH2 inhibitor treated Non-Hodgkins Lymphoma cell lines
Mutations within the catalytic domain of the histone methyltransferase (HMT) EZH2 have been identified in subsets of Non-Hodgkin Lymphoma (NHL) patients. These genetic alterations are hypothesized to confer an oncogenic dependency on EZH2 enzymatic activity in these cancers. We previously reported...
