A genome-wide association study identified LMO1, which encodes a LIM-domain-only transcriptional cofactor, as a neuroblastoma susceptibility gene that functions as an oncogene in high-risk neuroblastoma. Here we show that dβh promoter-mediated expression of LMO1 in zebrafish synergizes with MYCN to increase the proliferation of hyperplastic sympathoadrenal precursor cells, leading to a reduced latency and increased penetrance of neuroblastomagenesis. The transgenic expression of LMO1 also promoted hematogenous dissemination and distant metastasis, which was linked to neuroblastoma cell invasion and migration, and elevated expression levels of genes affecting tumor cell-extracellular matrix interaction, including loxl3, itga2b, itga3 and itga5. Our results provide in vivo validation of LMO1 as an important oncogene that promotes neuroblastoma initiation, progression, and widespread metastatic dissemination. High expression of LMO1 is associated with neuroblastoma (NB) metastases. Zhu et al. show that LMO1 synergizes with MYCN to promote NB development and metastasis in zebrafish and that LMO1 elevates expression of genes affecting tumor cell-extracellular matrix interaction and promotes NB cell invasion.
