IFNG and lung carcinoma: TNF receptor signaling pathway was significantly upregulated in ERVK-7.long in both lung cancer types (multivariate regression model, coefficient [LUAD] = 2.67, coefficient [LUSC] = 1.69, p value [LUAD] = 0.013, p value [LUSC] = 0.0005), whereas IFN-γ signaling was preferentially induced ERVK-7.short expression in LUAD (Fig. 6H; multivariate regression model, coefficient [LUAD] = 2.64, coefficient [LUSC] = 0.25, p value [LUAD] = 0.03, p value [LUSC] = 0.61).
