Decreased expression of this transcript in CRC and high activity in nine correlations (positive with CYP2B7P1, ADH1C, GGT5, AKRB10, AKR7A2, and MAOA and negative with ADH5, ALDH1A1, and PTGS1) in healthy intestines that were only positive with ADH1C in CRC were found (Table 5). This evidence concerns the gene GGT5 and colorectal carcinoma.
