Interestingly, oral administration of L. plantarum AS1 in rats with DMH-induced CRC suppressed lipid peroxidation and upregulated the expression of the antioxidant enzymes superoxide dismutase (SOD), glutathione S-transferase (GST), and catalase (CAT), leading to tumorigenesis eradication [261]. Here, CAT is linked to colorectal carcinoma.
