MYCN and neuroblastoma: In addition, the survival percent of the patients with NB in the MYCN low-expression group (n = 30) and the MYCN high-expression group (n = 30) was also studied and the data showed that the survival rate of the NB patients in the miR-98 low-expression group was significantly higher than that of the miR-98 high-expression group (P < 0.006) (Fig. 1D).
