PEX1 and hepatocellular carcinoma: In addition, important genes related to the response to OS were found among the altered genes in siNF-κB MCF-7, such as OXR1 and TMX1. Although none of the altered genes were common to all lists of redox metabolism-related genes, HPGD was found in the siNF-κB HCC-1954 and siNF-κB MDA-MB-231 lists, while PEX1 was found in the siNF-κB HCC-1954 and siNF-κB MCF-7 lists (as presented in the Venn diagram, Figure 2).
