Among the 76 proteins up-regulated, enrichments in genes involved in the “Immune system process”, “Antigen processing and presentation”, “Immune response” or “Response to interferon-gamma” were found (Figure 1C and Supplementary Figure S1) and were expected as they were known to be induced by IFN-γ from previous transcriptomics data from other melanoma cell lines [8]. Here, IFNG is linked to melanoma.
