Using microarrays we compared the whole genome gene expression profile of HP+ and HP- gastric erosions and normal adjacent mucosa to explain the possible role and response to HP infection and to get morphology related mRNA expression patterns. Experiment Overall Design: Total RNA was extracted from frozen gastric biopsy specimens of patients with Helicobacter pylori positive (HP+) and Helicobacter pylori negative (HP-) antrum erosions (ER+), and the corresponding, adjacent normal mucosae (ER-) and hybridized on Affymetrix HGU133 Plus 2.0 microarraysE-GEOD-5081http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-5081/samples/
