It is notable that no differences between ABCB5-WT and ABCB5-KD melanoma cells were detected for any of the phosphorylated high or low-energy metabolites quantified; this concerns PCr, nucleoside triphosphates (NTP; predominantly ATP), nucleoside diphosphates (NDP; predominantly ADP), and inorganic phosphate (Pi). This evidence concerns the gene ABCB5 and melanoma.
