Western blot was used to detect the levels of CRC‐specific proteins (COX2 and MUC2) and apoptotic proteins (Bax, Cleaved‐caspase3 and Bcl2); it was found that CRC mice showed increased protein levels of COX2, MUC2, Bax and Cleaved caspase3, and decreased Bcl2 level (Figure 2H). This evidence concerns the gene BAX and colorectal carcinoma.
