CKB and neuroblastoma: Notably, creatine kinase B (CKB), proprotein convertase subtilisin/kexin type 1 inhibitor (PCSK1N), OTU domain‐containing ubiquitin aldehyde‐binding protein 1 (OTUB1), neurotrophin receptor tyrosine kinase 3 (NTRK3), and nerve growth factor inducible (VGF) were identified as key genes to show a better or worse connections with the outcomes of NB patients (Figure 2D–H).
