ABSTRACT
<p><b>OBJECTIVE</b>To search differentially expressed proteins in serum of patients with Crohn disease.</p><p><b>METHODS</b>Serum protein samples from 4 patients with Crohn disease and 8 healthy adults were recruited cross-labeled with variant CyDye, and then followed by two-dimensional differential in-gel electrophoresis (2-D DIGE), image analysis, and identified by matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS).</p><p><b>RESULTS</b>The 2-D electrophoresis results were compared between the Crohn disease patients and the healthy adults. The spot 1058 expression in serum of Crohn disease patients increased by 1.68 folds as compared with healthy adults (P<0.05). The protein was identified as haptoglobin by mass spectrometry.</p><p><b>CONCLUSION</b>Up-regulating expression of haptoglobin in serum of Crohn disease patients may play a role in disequilibrium of immunity system.</p>
