Melanoma cells undergo the epithelial-to mesenchymal-like transformation [36]; thus, for the tested cell lines in this research, it is understandable that the base level of the GFAT-1 expression for melanoma cells was significantly higher for metastatic A375-P cells than for the primary WM35 cells (approximately 138%, data available in the Supplementary Materials Table S1). This evidence concerns the gene GFPT1 and melanoma.
