Abstract:
Objective To review the relationship between absence of expression of DPC4/SMAD4 gene and pathogenesis of pancreatic carcinoma(PC). Methods A summerized paper was made on the review of relative literatures. Results and Conclusions A new gene DPC4 (located on chromosome 18q21.1 region) has been identified as a candidate tumor suppression gene. SMAD4 belongs to the evolutionarily conserved family of SMADs proteins that are crucial intracellular mediators of signals from the transforming growth factor ?(TGF-?). In TGF-? super family signal pathways, SMAD4 plays a pivotal role .There is a close relationship between absence of expression of DPC4 gene and pathogenesis of pancreatic carcinoma.
