From Cistrome DB tool, we confirmed that there was one E-box binding motif (CACGTG) under the MYCN enriched peaks in IGF2BP1 promoter (Fig. 7A), which indicated MYCN is a potential transcription factor of IGF2BP1. Clinical relevance analysis revealed that MYCN was up-regulated in tumor tissues (Fig. 7B and C). This evidence concerns the gene MYCN and neoplasm.
