IFNG and melanoma: Ribas et al. showed that immune-related biomarkers, like the IFNγ signalling-related gene signature (analysed using the Nanostring nCounter as the average of the normalised expression levels of CXCL9, CXCL10, HLA-DRA, IDO-1, IFN-γ, and STAT1), have statistically significant associations with treatment response and PFS in patients with melanoma [91].
