IFNG and neoplasm: In a PC series [30], high tumor fusion burden (TFB)—measuring the number of gene fusions in a tumor—inversely correlated with TMB and immune suppressive signatures; conversely, it was positively associated with immune infiltration, PD-L1 expression on immune cells, and immune signatures (representing activation of T cells and M1 macrophages, checkpoint inhibitors, IFN-γ-induced T-cell activity, T-effector activation, and class I antigen processing), cell cycle progression, AR signaling, and ERG/ETS transcriptional activity.
