Identification of proteins found to be differentially expressed in H. pylori strains from PUD patients (n = 5) compared to NUD patients (n = 5).

“Comparison to 2DE databases” indicates spots for which identification was done by finding the corresponding spot on the standard H. pylori 2DE gel from the database [14]. All of the others were identified by PMF analysis. For each spot the average of the % Vol ± S.D. is indicated. In the Variation (DU/NUD) column: ↑, proteins for which the average of the % Vol of spots on DU 2DE maps was higher than that on NUD 2DE maps; ↓, proteins for which the average of the % Vol of spots on DU 2DE maps was lower than that on NUD 2DE maps; ↔, proteins that were shifted right in the DU 2DE-maps regarding their position on the NUD 2DE-maps. In the Variation (GU/NUD) column: ↑, proteins for which the average of the % Vol of spots on GU 2-DE maps was higher than that on the DU 2DE maps; ↓, proteins for which the average of the % Vol of spots on GU 2DE maps was lower than that on DU 2DE maps; = , proteins showing the same pattern of expression observed for the H. pylori strains associated with DU.
