Proline Oxidase Functions as a Mitochondrial Tumor Suppressor in Human Cancers

Abstract excerpt

Tumor metabolism and bioenergetics have become important topics for cancer research and are promising targets for anticancer therapy. Although glucose serves as the main source of energy, proline, an alternative substrate, is important, especially during nutrient stress. Proline oxidase (POX), catalyzing the first step in proline catabolism, is induced by p53 and can regulate cell survival as well as mediate...
