(Submitter supplied) We analyzed the genomic distribution of H3K27me3 in a clone of c-Myc iMEFs (clone C2) either i) wild-type for Ezh2, ii) in the presence of overexpressed exogenous Ezh2, iii) Ezh2-mutant, and iv) Ezh1/Ezh2 pre-deletion (Ezh1/Ezh2 introduced before deletion of endogenous Ezh2) and Ezh2 post-deletion rescue (Ezh2 re-introduced in Ezh2-mutant cells).

(Submitter supplied) Alterations of chromatin modifiers are frequent in cancer but their functional consequences remain often unclear. Focusing on the Polycomb protein EZH2 that deposits H3K27me3 mark, we showed that its high expression in solid tumors is a consequence, and not a cause, of tumorigenesis. In mouse and human models, EZH2 is dispensable for prostate cancer development and restrains breast tumorigenesis. High EZH2 expression in tumors results from a tight coupling to proliferation to ensure H3K27me3 homeostasis. more...

(Submitter supplied) Polycomb Repressive Complex 2 (PRC2) plays a key role in controlling transcriptional repression. It is thought to act at the level of the chromatin, where its enzymatic subunits Ezh1 and Ezh2 catalyse the di/tri-methylation of histone H3 on its lysine 27 (H3K27me3). We sought to assess several parameters of PRC2-mediated transcriptional repression. To this end we performed a comparative analysis of mES and iMEF cells following deletion of Ezh2, a time-course analysis following deletion of Ezh2 in iMEFs as well as rescue experiments with Ezh1 and Ezh2 before or after deletion of Ezh2.

(Submitter supplied) Multiple myeloma (MM) is the second most common hematological malignancy with poor prognosis. Enhancer of zeste homolog 2 (EZH2) is the enzymatic subunit of polycomb repressive complex 2 (PRC2), which catalyzes trimethylation of histone H3 lysine 27 (H3K27me3) for transcriptional repression. EZH2 have been implicated in numerous hematological malignancies, including MM. However, noncanonical functions of EZH2 in MM tumorigenesis are not well understood. more...

(Submitter supplied) Background: Polycomb repressive complex 2 (PRC2) is responsible for establishing and maintaining histone H3K27 methylation during cell differentiation and proliferation. H3K27 can be mono-, di-, or tri-methylated, resulting in differential gene regulation. However, it remains unknown how PRC2 specifies the degree and biological effects of H3K27 methylation within a given cellular context. One way to determine PRC2 specificity may be through alternative splicing of Ezh2, PRC2’s catalytic subunit, during cell differentiation and tissue maturation. more...

Previously, it was reported that, in order to sustain tumorigenicity of prostate cancer, EZH2 has noncanonical functions in interaction with AR for mediating gene activation, in addition to its canonical role as a transcriptional repressor and enzymatic subunit of Polycomb Repressive Complex 2 (PRC2). more...

(Submitter supplied) Prostate cancer is the most common cancer in men and AR downstream signalings promote prostate cancer cell proliferation. We identified RUNX1 is an androgen-regulated gene. In order to investigate the RUNX1 function in prostate cancer cells, we performed gene expression in AR-positive prostate cancer cell lines after siRUNX1 treatment. We also treated cells with vehicle or androgen to analyzed the effects of RUNX1 on AR function.

(Submitter supplied) The goal of this study was to delineate the important EZH2 direct target genes that mediate the oncogenic properties of EZH2 in HCC. The EZH2 direct target genes in two HCC cell lines were identified by chromatin immunoprecipitation microarray (ChIP-chip) analysis and later confirmed by independent ChIP-PCR. The functions of the target genes were further examined.

This study explores the role of poly(ADP-ribose) polymerase (PARP) on global gene expression in a lymphoblastoid B cell line. We found that inhibition of PARP catalytic activity with olaparib resulted in global gene deregulation, affecting approximately 11% of genes expressed. more...
