To further investigate the lncRNA regulating MZF1 expression in NB, mining of public datasets (GSE16476 and GSE62564) revealed that MORF4L2 antisense RNA 1 (MORF4L2‐AS1), MZF1‐AS1, and PCOLCE antisense RNA 1 (PCOLCE‐AS1) were associated with MZF1 levels (Figure2A). The gene discussed is MORF4L2-AS1; the disease is neuroblastoma.
