  1. ...), and there is ample functional evidence for its decisive role in malignant transformation and tumorigenesis (Kovar 2010). However, ;10% of ES are characterized by alternative EWSR1 fusion partners from the ETS family (ERG, ETV1, ETV4, FEV ), and the oncogenic role of EWSR1/ERG, the second most frequent ES gene fusion...
  2. ...interactions (Fig. 3D, right panel). We found EZH2, a subunit of the Polycomb repressive complex 2 (PRC2), specifically targeting enhancer hubs driven by AR and ERG binding (Supplemental Fig. S14), suggesting that PRC2 regulates those interaction hub regions, which is consistent with the previous model...
  3. ...-specific enhancer within the rs1859962 risk LD block that establishes a 1-Mb chromatin loop with the SOX9 gene. The rs8072254 and rs1859961 SNPs mapping to this enhancer impose allele-specific gene expression. The variant allele of rs8072254 facilitates androgen receptor (AR) binding driving increased enhancer...
  4. ...Chips. SA-DNAm changes are highly reproducible and they are enriched in intergenic and nonpromoter regions of developmental genes. Furthermore, SA-hypomethylation in particular appears to be associated with H3K9me3, H3K27me3, and Polycomb-group 2 target genes. We demonstrate that ionizing irradiation...
  5. ..., and are commonly paired with promoters that are repressed by the Polycomb repressive complex in order to facilitate cellular reprogramming by master regulatory factors (Taberlay et al. 2011). In contrast, we found that cancer cells are rendered resistant to cellular reprogramming if the cognate enhancer...
  6. ...occurrence of TFBSs. Indeed, in recent work (Arnold et al. 2012b) we applied the MARA approach to ChIP-seq data mapping the dynamics of trimethylation at lysine 27 of histone 3 (H3K27me3) and identified TFs involved in recruiting this epigenetic mark that is set by the Polycomb system. In ISMARA...
  7. ...bp of one another. Indeed, Roder et al. showed that NF-Yand SP1 proteins bind to each other and that they cobind to the same promoter (Roder et al. 1999). In another example, YY1was shown to interactwithMYC, and cooperatively, the two TFs regulate the expression of the ITGA3 gene of the a3b1integrin...
