The screening and the functional pathway analysis of differential genes correlated with coronary heart disease of blood stasis syndrome / 中国中西医结合杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the function and target pathway of the correlated differential gene of coronary heart disease (CHD) of blood stasis syndrome (BSS).</p><p><b>METHODS</b>Patients of the genealogical CHD of BSS (group A) and the genealogical CHD of non-BSS (group B), the genealogical non-CHD of BSS (group C), the genealogical healthy subjects (group D), the non-genealogical CHD of BSS (group E), the non-genealogical healthy subjects (group F) were recruited in this study. The differential gene expression spectrums were studied using gene chip technique. The molecular functions of differential genes were analyzed and illustrated by gene ontology (GO) analysis. The differential gene pathways were found out at BioCarta and KEGG. The meaningful target pathways were screened by hypergeometric distribution statistical method. The differential genes were verified using Real-time fluorescent quantitative PCR.</p><p><b>RESULTS</b>(1) By screening the gene chip data (with FC > or =3), we found the expressions of differential genes of CHD of BSS were mainly involved in chemokine, interleukin cytokine, alexin system, matrix metal proteinase system, fibroblastic growth factor, endothelial cell adhesion molecule, and so on. (2) By GO analysis of related differential genes (P < 0.05), we found the molecular functions of differential genes associated with CHD BSS. (3) By BioCarta and KEGG pathway analysis, we found the target pathways of the hereditary correlated differential genes of CHD BSS with significance were mainly involved in inflammation, plaque formation, endothelial injury, and so on. The results of Real-time fluorescent quantitative RT-PCR proved the accuracy of the gene chip.</p><p><b>CONCLUSION</b>The hereditary correlated differential genes of CHD BSS were closely associated with inflammation, plaque formation, and endothelial injury.</p>
