NF1 and metastatic melanoma: A similar decrease in cell viability was observed in an NF1-null metastatic melanoma cell line, MeWo [25] when glutamine was removed from the media, whereas, another melanoma cell line, 92.1 [26], that does not carry any NF1 mutation/deletion did not show any decrease in cell viability after glutamine removal from the media (Supplementary Figure 1, left panel).
