While SNAI2 was shown to be positively correlated with MITF, the expression of CDH1 did not correlate with the expression of SNAI2 in the TCGA melanoma tumors which is consistent with the published findings in melanoma and melanocyte samples (Shirley et al., 2012), despite CDH1 being a canonical target of SNAI2 (Cano et al., 2000). This evidence concerns the gene MITF and melanoma.
