We further stratified the MOXD1 expression in the tumors from these individuals according to the International Neuroblastoma Staging System (INSS) stages and low- and high-risk groups and observed a negative correlation between MOXD1 and more advanced tumor stage and high-risk neuroblastomas (Fig. 1, B and C, and fig. Here, MOXD1 is linked to neuroblastoma.
