(Submitter supplied) The ETS transcription factor ERG is involved in several cancers including leukemia. However, ERG domains and co-factors involved in leukemogenesis remain largely uncharacterized and as a transcription factor it is currently undruggable. Here, we report a critical role for the conserved amino-acid proline at position 199, at the 3’ end of the PNT domain, for ERG’s leukemogenic activity. Specifically, we demonstrate that it is required for ERG-induced self-renewal and restriction of myeloid differentiation in hematopoietic progenitor cells and for initiation of leukemia in mouse transduction/transplantation models. more...

(Submitter supplied) The Ets transcription factor, ERG, plays a central role in definitive hematopoiesis and its overexpression in acute myeloid leukemia is associated with a stem cell signature and bad prognosis. However, little is known about the underlying mechanism by which ERG causes leukemia. Therefore we sought to identify ERG targets that participate in development of leukemia by integration of expression arrays and Chromatin immunoprecipitation.

(Submitter supplied) Here we show that pan-haematopoietic ERG expression driven by the Vav promoter induces an early progenitor myeloid leukemia in transgenic mice. Integrated genome-scale analysis of gene expression and ERG binding profiles revealed that ERG activates a transcriptional program similar to human AML stem/progenitor cells and human AML with high ERG expression. We further show that ERG induces expression of the Pim1 kinase oncogene through a novel enhancer element validated in transgenic mice, and Pim1 inhibition disrupts growth and induces apoptosis of ERG-driven leukemic cells. more...

(Submitter supplied) Chromatin modifiers play critical roles in epidermal development, but the functions of histone deacetylases in this context are poorly understood. We find that the Class I HDAC, HDAC3, is expressed broadly in embryonic epidermis, and is required for its orderly stepwise stratification. Stability of HDAC3 protein in vivo is reliant on NCoR and SMRT, which function redundantly in epidermal development. more...

(Submitter supplied) Fusion proteins involving the ETS factor ERG have been associated with multiple cancers such as Ewing's sarcoma and prostate cancer. In acute myeloid leukemias harboring t(16;21) another ERG fusion protein is expressed, FUS-ERG. Here, we found that this FUS-ERG oncofusion protein acts in the context of a heptad of proteins (ERG, FLI1, GATA2, LYL1, LNMO2, RUNX1 and TAL1) central to proper expression of genes involved in maintaining a stem cell hematopoietic phenotype. more...

(Submitter supplied) Erg is an ETS family transcription factor frequently overexpressed in human leukemias and has been implicated as a key regulator of hematopoietic stem cells (HSCs). However how Erg controls normal hematopoiesis, particularly at the stem cell level, remains poorly understood. Using homologous recombination, we generated an Erg knockdown allele (Ergkd) in which Erg expression can be restored upon Cre-mediated excision of a Stopper cassette. more...

(Submitter supplied) Deregulated expression of ETS transcription factors with oncogenic and tumor suppressor function occurs frequently in prostate cancer leading to profound alterations of the cancer transcriptome. By integrating genomic and functional studies we identified key targets of the aberrantly expressed ETS factors, ERG and ESE3. Altered expression of ETS factors led to the induction of the polycomb group protein EZH2 and silencing of the tumor suppressor Nkx3.1. more...

(Submitter supplied) Half of prostate cancers are caused by a gene-fusion that enables androgens to drive expression of the normally silent ETS transcription factor ERG in luminal prostate cells1-4. Recent prostate cancer genomic landscape studies5-10 have reported rare but recurrent point mutations in the ETS repressor ERF11. Here we show these ERF mutations cause decreased protein stability and ERF mutant tumours are mostly exclusive from those with ERG fusions. more...
