Abstract： Objective By proteomic analysis of differentially expressed protein profiling in pancreatic cancer using antibody microarray, new tumor marker of pancreatic cancer was supposed to be discovered. Methods The antibody microarray containing 378 monoclonal antibodies was applied to detect the differentially expressed proteins of 7 sets of pancreatic ductal adenocareinoma pooled samples and their paired normal pancreas tissues pooled samples. Results 11 up-regulated proteins (UbcH6, GABA b R2, Plakophilin 2a, Inhibitor 2, Nestin, ShcC, PRK2, Neurogenin 3, STAT 3, NHE-3 and SRP54) and 9 down- regulated proteins (DCC, HPV-16 L1, RACKI, Gelsolin, Rabaptin-5, DBP2, IKKa/I, c-Cbl, FXR2) were found in pancreatic cancer. Conclusions Antibody microarray was an effective comparative proteomic technology. These dys-regulated proteins facilitated to elucidate the mechanisms of pancreatic cancer and to identify new diagnostic markers and therapeutic targets.
