STMN1 and hepatocellular carcinoma: The immunohistochemical staining images of the remaining eight prognostic FRGs or HRGs from HPA showed that the protein expression of TXNRD1 and STMN1 were higher in HCC tissues, that of UGP2 was higher in normal liver tissues, while the protein expression of SLC2A1, LDHA, EIF2AK4, ILVBL, and STC2 showed no significant difference between normal liver tissues and HCC tissues (Figure 10B).
