abstract = {Neuroblastoma is the most common solid tumor in infants
accounting for approximately $15\%$ of all cancer-related
deaths. Over $50\%$ of high-risk neuroblastoma relapse,
emphasizing the need of novel drug targets and therapeutic
strategies. In neuroblastoma, chromosomal gains at
chromosome 17q, including IGF2BP1, and MYCN amplification at
chromosome 2p are associated with adverse outcome. Recent,
pre-clinical evidence indicates the feasibility of direct
and indirect targeting of IGF2BP1 and MYCN in cancer
treatment.Candidate oncogenes on 17q were identified by
profiling the transcriptomic/genomic landscape of 100 human
neuroblastoma samples and public gene essentiality data.
Molecular mechanisms and gene expression profiles underlying
the oncogenic and therapeutic target potential of the 17q
oncogene IGF2BP1 and its cross-talk with MYCN were
characterized and validated in human neuroblastoma cells,
xenografts and PDX as well as novel IGF2BP1/MYCN transgene
mouse models.We reveal a novel, druggable feedforward loop
of IGF2BP1 (17q) and MYCN (2p) in high-risk neuroblastoma.
This promotes 2p/17q chromosomal gains and unleashes an
oncogene storm resulting in fostered expression of 17q
oncogenes like BIRC5 (survivin). Conditional,
sympatho-adrenal transgene expression of IGF2BP1 induces
neuroblastoma at a $100\%$ incidence. IGF2BP1-driven
malignancies are reminiscent to human high-risk
neuroblastoma, including 2p/17q-syntenic chromosomal gains
and upregulation of Mycn, Birc5, as well as key
neuroblastoma circuit factors like Phox2b. Co-expression of
IGF2BP1/MYCN reduces disease latency and survival
probability by fostering oncogene expression. Combined
inhibition of IGF2BP1 by BTYNB, MYCN by BRD inhibitors or
BIRC5 by YM-155 is beneficial in vitro and, for BTYNB,
also.We reveal a novel, druggable neuroblastoma oncogene
circuit settling on strong,
transcriptional/post-transcriptional synergy of MYCN and
IGF2BP1. MYCN/IGF2BP1 feedforward regulation promotes an
oncogene storm harboring high therapeutic potential for
combined, targeted inhibition of IGF2BP1, MYCN expression
and MYCN/IGF2BP1-effectors like BIRC5.},
