The data presented here are consistent with and extend our previous work, in which we showed that melanoma cell lines with low levels of MITF expression (NZM9, NZM11, NZM22, NZM40, and NZM52) have higher (∼23-fold) migratory potential than melanoma cell lines with high MITF expression levels (NZM6, NZM12, NZM15, NZM42, NZM45). This evidence concerns the gene MITF and melanoma.
