Genetic alterations of the ornithine decarboxylase gene in human colorectal cancers.

Abstract excerpt

Ornithine decarboxylase (ODC), a critical regulatory enzyme for polyamine biosynthesis, is strictly regulated in human cells. Several studies suggested the importance of elevated enzymatic activity and altered biochemical characteristics of ODC in malignant cells. Because mutation of ODC in primary human hepatocellular carcinoma has been reported, we examined whether the genetic alterations, such as mutations or...
