Furthermore, a correlation activity was observed in healthy tissue (positive with ADH5 and ALDH1A1 positive and negative with CYP2B7P1, ADH1C, AKRB10, EPHX2, and MAOA) in comparison to CC vs. AC (only negative with MAOA) and CRC (only positive with EPHX1) (Table 5). Here, EPHX2 is linked to colorectal carcinoma.
