In addition, we used quantitative reverse transcription polymerase chain reaction (qRT-PCR) to verify the expression level of core genes in a mouse atherosclerosis model.<h4>Results</h4>There were 29 common differentially expressed genes (DEGs) between the GSE28829 and GSE41571 datasets, and the DEGs were mainly enriched in the chemokine signaling pathway and the <i>Staphylococcus aureus</i> infection pathway (P<0.05). We identified 6 core genes (<i>FPR3, CCL18, MS4A4A, CXCR4, CXCL2</i>, and <i>C1QB</i>) in the protein-protein interaction (PPI) network, 3 of which (<i>CXCR4</i>, <i>CXCL2</i>, and <i>CCL18</i>) were markedly enriched in the chemokine signaling pathway. qRT-PCR analysis showed that the messenger RNA levels of two core genes (<i>CXCR4</i> and <i>CXCL2</i>) increased significantly during plaque progression in the mouse atherosclerosis model.<h4>Conclusions</h4>In summary, bioinformatics techniques proved useful for the screening and identification of novel biomarkers of disease.
