To recapitulate the heterogeneity of immune cell infiltration seen in human melanoma cohorts, including the human TCGA melanomas, we pooled gene expression data derived from tumors from untreated versus treated mice and again asked whether the genes within the Hallmark β‐catenin signaling gene set correlated either with MITF or the immunome gene expression signature in the different tumors. This evidence concerns the gene MITF and melanoma.
