Interaction Information:

Comment To further investigate whether uric acid (UA) inhibits high glucose (HG)-induced activation of Wnt signaling, ARPE19 cells and human retinal Muller cells (HMC) were cultured with HG for and subsequently treated with different concentrations of UA. UA inhibited HG-induced LRP6 phosphorylation in a concentration- dependent manner in both ARPE19 cells and HMC. Phosphorylation of beta-catenin is the initial step for its degradation. Phosphorylated beta-catenin (p-beta-catenin) was significantly decreased by HG, which resulted in subsequent increases of both cytosolic and nuclear beta-catenin levels in ARPE19 cells. These changes of beta-catenin induced by HG were reversed by UA.
