Figure 6. Genetic alteration and protein expression analysis of five-gene signature in HCC. (A) The summary of genetic alterations of the five-gene signature in the cBioPortal database. (B, C) The genetic alteration of five-gene signature correlated with poor overall survival probability (B) and recurrence-free probability (C). (D) The representative protein expression of the CLN3, HGF, TRIM22, and SNRPD1 in HCC and non-HCC tissues. (E–H) Association of the risk score with gender (E), TNM stage (F), BCLC stage (G), and CLIP score (H).
