| Summary: | The functions of genes involved in idiopathic portal hypertension (IPH) remain unidentified.
The present study was undertaken to identify the functions of genes expressed in blood
samples from patients with IPH through comprehensive analysis of gene expression using
DNA microarrays. The data were compared with data from healthy individuals to explore the
functions of genes showing increased or decreased expression in patients with IPH. In cluster
analysis, no dominant probe group was shown to differ between patients with IPH and healthy
controls. In functional annotation analysis using the Database for Annotation Visualization
and Integrated Discovery tool, clusters showing dysfunction in patients with IPH involved
gene terms related to the immune system. Analysis using network-based pathways revealed
decreased expression of adenosine deaminase, ectonucleoside triphosphate
diphosphohydrolase 4, ATP-binding cassette, subfamily C, member 1, transforming growth
factor-β, and prostaglandin E receptor 2; increased expression of cytochrome P450, family 4,
subfamily F, polypeptide 3, and glutathione peroxidase 3; and abnormalities in the immune
system, nucleic acid metabolism, arachidonic acid/leukotriene pathways, and biological
processes. These results suggested that IPH involved compromised function of
immunocompetent cells and that such dysfunction may be associated with abnormalities in
nucleic acid metabolism and arachidonic acid/leukotriene-related synthesis/metabolism. |
