Description: Proteomic technology was employed to analyze serum samples from healthy subjects (10 cases) and gastritis patients with negative and positive Helicobacter pylori (Hp) infection (15 cases each). The serum proteins were separated by two-dimensional (2-D) gel electrophoresis and analyzed by a computer-aided program. The altered proteins in expression were then identified by mass spectrometry and validated by Western blotting. Compared to those in normal control, proteins in at least six areas of 2-D gels were found to significantly increase their expression levels in both Hp-negative and Hp-positive serum samples. These proteins were identified by mass peptide fingerprinting and confirmed by Western blotting to be the truncated or cleaved protein fragments of apolipoprotein A-I and alpha-1 antitrypsin, two well-known acute-phase proteins. We conclude that the degradation or metabolization of acute-phase proteins, apolipoprotein A-I, and alpha1-antitrypsin, is a common response to gastric inflammation irrespective of Hp infection. © 2008 Springer Science+Business Media, LLC.
