To verify the expression differences of FTCD, G6PD, PON1 and TMEM45A, protein expressions in 82 cases of HCC and para-cancerous tissues was detected using immunohistochemical assays and reflected higher expressions of FTCD, PON1, and TMEM45A genes in para cancerous tissues (Fig. 14A, C, D) and higher expressions of G6PD genes in cancerous tissues (Fig. 14B). This evidence concerns the gene G6PD and hepatocellular carcinoma.
