PPID and neoplasm: Furthermore, the single NRGs (CHMP1A, CHMP3, FTH1, TRAF5, TYK2, VDAC1, and PPID) were associated with some clinicopathological parameters as well; specifically, TRAF5, TYK2, VDAC1, FTH1, and CHMP1A were correlated with the survival status, while TRAF5, CHMP3, FTH1, PPID, TRAF, and TYK2 showed great correlation with the tumor grade (Figures 4(c), 4(d), and S2).
