We analyzed a publicly available dataset of single-nuclei RNA-seq (snRNA-seq) from 11 neuroblastomas previously presented by Bedoya-Reina et al. (17) and found that expression of MOXD1 was low in noradrenergic cell clusters and high in undifferentiated MES-like tumor cell clusters (Fig. 2A). This evidence concerns the gene MOXD1 and neoplasm.
