Results: Armadillo repeat containing 12 (ARMC12) was identified as a MYC-interacting modulator within liquid condensates to up-regulate critical nucleoporin-encoding targets (NUP62/NUP93/NUP98), which promoted nuclear pore complex (NPC) biogenesis to facilitate nuclear trafficking of oncogenic effectors, thereby enhancing invasion and metastasis of NB. This evidence concerns the gene NUP93 and neuroblastoma.
