Mechanistic analysis of pancreatic ductal carcinogenesis in hamsters.

abstract：OBJECTIVES:The present study screened the SMAD4 gene in an Indian population of patients with pancreatic ductal adenocarcinoma (PDAC) for the presence of homozygous deletions and mutations. The effect of these genetic alterations on Smad4 protein expression and patient survival was also evaluated. METHODS:This study w...
