TNFAIP3 and neoplasm: The proteomic expression of TNFAIP3 in tumor stages, as analyzed by CPTAC proteomic data (Figure 3e), shows a gradual decrease in TNFAIP3 protein expression as tumor staging progresses, and a significant negative correlation between TNFAIP3 protein levels and tumor stage (Spearman's ρ = −0.63, p < 0.001).
