Figure 4. Correlations between the LDCD-RGs score and the classical cancer-related metabolic, immune and cell death pathways. (A) Analysis of differences in activity of classical metabolic pathways among 3 subgroups of KIRC. (B) Analysis of differences in activity of classical immune pathways among 3 subgroups of KIRC. (C) Analysis of differences in activity of classical cell death pathways among 3 subgroups of KIRC. (*p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001). Abbreviations: LDCD-RGs: LDCD-related genes; KIRC: kidney renal clear cell carcinoma.
