ERBB2 and melanoma: For example, compared to the control, neural crest-related genes, including v-erb-b2 erythroblastic leukemia viral oncogene homolog 2 (erbb2), erbb3a, erbb3b, sox9b, twist-related protein 1a (twist1a), twist1b, and twist3 were strongly downregulated in melanoma while their expression levels remained higher in nevi.
