Loss of heterozygosity (LOH) of chromosome arm 18q is frequent in gastrointestinal cancers. Over 90% of pancreatic carcinomas have 18q LOH. Bi-allelic inactivation of the MADH4/DPC4/SMAD4 gene at 18q21.1 is seen in about half of pancreatic carcinomas with 18q LOH. In the remaining tumors with 18q LO
DPC4/SMAD4 is a candidate tumor suppressor gene with a strikingly high frequency of gene alterations in pancreatic cancer that suggests a discrete role for DPC4 in these tumors. DPC4 tumor-suppressive function has been implicated to mediate the transforming growth factor-b (TGFb)Β±suppressive pathway
