SIX1 and Nephroblastoma: To identify putative target genes of SIX1-Q177R in Wilms tumor and characterize these as either tumor-specific or conserved normal kidney regulatory targets, we integrated three SIX1 ChIP-seq peak sets from SIX1 tumor, SIX1-Q177R tumor and from hFK (Wegert et al., 2015; O'Brien et al., 2016).
