Screening of gene expression profiles in gastric epithelial cells induced by <i>Helicobacter pylori</i> using microarray analysis

Abstract

In this microarray analysis of gene expression induced by H. pylori in gastric epithelial cells, we identified a large number of unsuspected genes affected by H. pylori. Further, we show that unsupervised hierarchical cluster analysis can provide useful insight into the possible contribution of genes in specific pathways, based on their profile of expression.
