Specifically, we examined the expression of ZMYM1, SH3BGR, GSKIP, CBL, and WDR81 in: (i) differentiated tissues, including adrenal gland and other normal tissues, (ii) undifferentiated tissues, encompassing neural crest cell lines and neural precursor cells, (iii) tumor tissues, involving NB tumors and NB xenografts (Fig. 2 and Supplementary Table 1). The gene discussed is GSKIP; the disease is neuroblastoma.
