Key Event Relationship Description
Reactive oxygen species (ROS) increase causes beta-catenin stabilization leading to the activation. RSO may activate beta-catenin by releasing the nucleoredoxin (NRX), a thioredoxin family protein, mediated block on Dishevelled (Dvl) activity which is importantt for beta-catenin stabilization [Korswagen, 2006, Funato, 2006].
Evidence Collection Strategy
Evidence Supporting this KER
Biological Plausibility
ROS which promotes the cancer progression induces several pathways including Wnt/beta-catenin pathway [Korswagen, 2006, Funato, 2006].
Empirical Evidence
Lycopene, one of the major carotenoid natural products with antioxidant activity, induces apoptosis of gastric cancer cells by inhibiting nuclear translocation of beta-catenin [Kim, 20019]. ROS generated by arsenic mediates tumorigenesis through Wnt/beta-catenin pathway in which beta-catenin expression increases and activated [Zhang, 2011].
