Core Tip

Core tip: This study demonstrates that a treatment with 40% (w/w) brewers’ rice modulated the Wnt signaling pathway. Feeding 20% (w/w) brewers’ rice markedly improved the antioxidant level. These results strongly imply the potential use of brewers’ rice in future applications to combat oxidative stress and colon cancer.
