|All life stages||Moderate|
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 Supporting this KER
ROS which promotes the cancer progression induces several pathways including Wnt/beta-catenin pathway [Korswagen, 2006, Funato, 2006].
