Our previous studies have shown a prominent upregulation of NDRG1 in the Dp44mT- and DpC-treated cancer cell lines derived from pediatric solid tumors, including neuroblastomas (Paukovcekova et al., 2020; Macsek et al., 2022); thus, we evaluated the NDRG1 levels after combined treatments of SH-SY5Y and SK-N-BE(2) cells (Figure 8). This evidence concerns the gene NDRG1 and neuroblastoma.
