Expression of both TARID (NR_109982) and the TARID isoforms KF484511 and KF484512 (isoforms reported to have the strongest demethylation activity) was much lower in CCSKs than in Wilms tumors; in most CCSKs TARID was undetectable (Figure 5C, 5D). This evidence concerns the gene TARID and Nephroblastoma.
