For example, orally administered anthocyanin-rich blueberry extract attenuates the development of DSS-induced experimental colitis in mice by reducing the accumulation of myeloperoxidase and malondialdehyde in the colon and prostaglandin E2 levels in serum while increasing the levels of SOD and catalase compared to untreated mice with colitis [237]. This evidence concerns the gene MPO and colitis.
