To investigate correlations between PA2G4 and MYCN or MYC in the context of neuroblastoma and neuroendocrine development, we analyzed publicly available single-cell datasets from the neuroblastoma atlas (NBAtlas, Bonine et al., 2024 [18]) (Supplementary Figure S2) and the normal adrenal gland (Jansky et al., 2021 [19]) (Supplementary Figure S3). Here, MYCN is linked to neuroblastoma.
