Disease relevance of EWSR1

 

Psychiatry related information on EWSR1

  • OBJECTIVES: To explore and test methods for the operation of a national Early Warning System (EWS) in Denmark and to support decision making by the Danish Centre for Evaluation and Health Technology Assessment on this issue [5].
  • BACKGROUND: While cognitive formulations of eating disorders emphasise the role of dysfunctional assumptions regarding eating, weight and shape (EWS), less is known about the role of dysfunctional assumptions that are unrelated to EWS and those linking beliefs about EWS with negative beliefs about the self or the world [6].
 

High impact information on EWSR1

  • This indicates that the EWS-FLI1 fusion protein may act as an aberrant transcription factor, but the exact mechanism of oncogenesis remains unknown [7].
  • Our results implicate TGF-beta RII as a direct target of EWS-FLI1 [7].
  • Ewing sarcoma and related peripheral primitive neuroectodermal tumours share recurrent translocations that fuse the gene EWSR1 (formerly EWS) from 22q-12 to FLI1 and genes encoding other ETS transcription factors (which bind DNA through the conserved ETS domain) [7].
  • We have found that EWS/FLI1 and structurally related fusion proteins upregulate manic fringe (MFNG), a recently described member of the Fringe gene family instrumental in somatic development [8].
  • EWS/FLI1, a fusion gene found in Ewing's sarcoma, encodes a transcriptional regulator and promotes cellular transformation by modulating the transcription of specific target genes [8].
 

Chemical compound and disease context of EWSR1

 

Biological context of EWSR1

  • Phylogenetically conserved restriction fragments in the vicinity of EWSR1 and EWSR2, the genomic regions where the breakpoints of chromosome 22 and chromosome 11 are, respectively, have allowed identification of transcribed sequences from these regions and has indicated that a hybrid transcript might be generated by the translocation [14].
  • This study thus has demonstrated that the EWSR1-ATF1 chimera represents a fusion gene that can be associated with different tumor types [2].
  • In this article, we report that POU5F1 was fused to EWSR1 in a case of undifferentiated sarcoma derived from pelvic bone with chromosomal translocation t(6;22)(p21;q12) [15].
  • Activation of the EWSR1-ATF1 oncogene is probably an early step in the transformation process, but the overall gene expression patterns are likely to vary considerably between AFH and CCS, in keeping with their clinicopathologic differences [2].
  • Furthermore, fluorescence in situ hybridization (FISH) with cosmid probes corresponding to loci flanking the EWSR1 region demonstrated no split of chromosome 22 in all analyzed interphase nuclei [16].
 

Anatomical context of EWSR1

 

Associations of EWSR1 with chemical compounds

 

Physical interactions of EWSR1

  • The region on EWS which interacts with ZFM1 maps to 37 amino acids within its NTD [20].
  • Following a scheme similar to previously described translocations in Ewing tumors, a t(2;22) chromosome translocation fuses the N-terminal domain of EWS to the ETS DNA binding domain of FEV [24].
  • Employing yeast two-hybrid cloning we isolated the seventh largest subunit of human RNA polymerase II (hsRPB7) as a protein that specifically interacts with the amino terminus of EWS [25].
  • Here, we show that EWS interacts with Pyk2, a protein tyrosine kinase implicated in a variety of signal transduction processes [23].
  • Desmoplastic small round cell tumor (DSRCT) is a malignant human cancer that is associated with a specific t(11;22) chromosome translocation, where 265 amino acids from the EWS amino-terminus are fused to the DNA binding domain of the WT1 tumor suppressor gene [26].
 

Enzymatic interactions of EWSR1

  • STAT3 activation was assessed by immunohistochemistry using a monoclonal antibody specific for tyrosine(705)-phosphorylated STAT3 (pSTAT3(tyr705)) and a tissue microarray containing 49 paraffin-embedded ESFT tumours with known EWS translocations [27].
 

Regulatory relationships of EWSR1

  • Based on this hypothesis, we investigated the effect of EWS on the activation of nuclear receptors that are activated by CBP [19].
  • EWS/ETS fusions activate telomerase in Ewing's tumors [28].
  • The splicing factor U1C represses EWS/FLI-mediated transactivation [29].
  • Exogenous IGFBP-3 remarkably inhibits EWS growth, both in monolayer and anchorage-independent conditions, and significantly reduces cell motility [30].
  • We have previously reported that cyclin E expression was upregulated in EFT cells and in EWS-Fli1 transformed fibroblastic cells [31].
