Figure 2C shows the 11 favorable factors (PDE1A, ABCB1, NEDD8, ARF6, KCNJ8, P2RY2, ECM2, P2RX1, RAMP3, CTSW, and TMSB4X) and 14 risk factors (CYP26A1, SRPX, BCHE, GNAZ, CRMP1, ADCY2, MAPK8IP2, ENO2, MIF, REPS2, TRPS1, CEBPG, SLC22A1, and BAI3) in NPC. Significant correlations between them are also displayed (all correlations with p > 0.0001 were filtered out). The Kaplan–Meier (KM) survival analysis revealed that the progression-free survival (PFS) was statistically significant in those patients with differentially expressed favorable or risk factors (Figure 3, p < 0.05). The gene discussed is ARF6; the disease is nasopharyngeal carcinoma.
