Genetic alterations in human gastrointestinal cancers. The application to molecular diagnosis.

Abstract excerpt

Gastrointestinal cancers involve genetic alterations in multiple oncogenes, multiple tumor suppressor genes, and multiple DNA repair genes. However, common and different genetic changes are observed in esophageal, gastric, and colorectal carcinomas, respectively. Inactivation of the p53 gene and expression of CD44 abnormal transcripts are common events that serve as a powerful tool for cancer diagnosis. Gene...
