Two-sided Pearson’s correlation study and Student’s t-test showed that lncNB1 RNA expression positively correlated with MYCN amplification (Fig. 8a), N-Myc mRNA expression (Supplementary Fig. 9a) as well as DEPDC1B mRNA expression (Fig. 8b), and that RPL35 and E2F1 mRNA expression also positively correlated with DEPDC1B mRNA expression in the 493 human neuroblastoma tissues (Fig. 8c, d). This evidence concerns the gene LINC02525 and neuroblastoma.
