Research Abstract

The outer skin can be observed simply. Therefore we administered acetaldehyde to the Aldh2-deficient mice subcutaneously. Squamous cell carcinomas occurred on the back skins of the Aldh2--deficient mice and we examined them molecular biologically and pathologically.
It is well known that the Aldh2-deficient individuals should have greater risks of the incidence of the oropharyngeal or the esophageal cancer by drinking.
We apply this result to the medical treatment and the prevention of cancers.
