[Comparative proteomics of pancreatic cancer].

Objective: To identify differentially expressed proteins between pancreatic tumor tissues and the adjacent noncancerous tissues by comparative proteomics analysis.

Methods: Six pairs pancreatic tumor tissues and the adjacent noncancerous tissues were obtained and selected for two-dimensional polyacrylamide gel electrophoresis (2-DE) analysis. The differentially expressed proteins were identified using the PDQuest 2-D analysis software.
