NGFR and melanoma: Analyses of the expression of the neural crest cell marker p75/CD271, another melanoma‐initiating cell marker (Boiko et al, 2010; Civenni et al, 2011), by Western blot and Q‐PCR, consistently revealed its upregulation in A375 and SKMEL5 cells that overexpressed ZEB1 (Fig 4A and B, Appendix Fig S3B).
