IGF2BP1 induces neuroblastoma via a druggable feedforward loop with MYCN promoting 17q oncogene expression [mouse RNA-seq]

Chromosome 17q gain is an independent prognostic marker in neuroblastoma, harboring several potential oncogenes including IGF2BP1 and BIRC5. IGF2BP1 was shown to be upregulated in unfavorable neuroblastoma and correlates with poor patient survival. Here, we report that overexpression of IGF2BP1 in a transgenic mouse model induces neuroblastoma with all characteristics known for human neuroblastoma, including MYCN upregulation and genomic aberrations. Furthermore, we demonstrate that genes located at chromosome 17q have an exceptionally high potential as therapeutic targets in addition to a combined inhibition of IGF2BP1 and BIRC5 resulting in additive effects.
