In cell lines, in accordance to the human protein atlas (HPA) accessible consensus normalized expression (“NX”) values, the highest level of CD146’s RNA was observed in endothelial (i.e., HUVEC/TERT2, NX-value: 125.3), skin (i.e., TIME, NX-value:122.3), and melanoma (i.e., WM-115, NX: 97.3) cells. This evidence concerns the gene MCAM and melanoma.
