Research Abstract

Plasma membrane-associated sialidase is up-regulated in various human cancers including colon cancer. The transgenic mice develop hyperinsulinemia and subsequently insulin resistance, and also are susceptible to induction of colonic aberrant crypt foci by a carcinogen, azoxymethane. Analysis of the pathogenesis revealed that NEU3 activates Wnt signaling, which is thought to be important for cancer progression and also for beta cell growth in pancreatic islets, suggesting an influence of NEU3 on the two diseases probably via Wnt activation.
