Abstract
Background Foam cells play crucial roles in all phases of atherosclerosis. However, until now, the specific mechanisms by which these foam cells contribute to atherosclerosis remain unclear. We aimed to identify novel foam cell biomarkers and interventional targets for atherosclerosis, characterizing their potential mechanisms in the progression of atherosclerosis. Methods Microarray data of atherosclerosis and foam cells were downloaded from the Gene Expression Omnibus (GEO) database. Differentially expression genes (DEGs) were screened using the "LIMMA" package in R software. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis and Gene Ontology (GO) annotation were both carried out. Hub genes were found in Cytoscape after a protein-protein interaction (PPI) enrichment analysis was carried out. Validation of important genes in the GSE41571 dataset, cellular assays, and tissue samples. Results A total of 407 DEGs in atherosclerosis and 219 DEGs in foam cells were identified, and the DEGs in atherosclerosis were mainly involved in cell proliferation and differentiation. CSF1R and PLAUR were identified as common hub genes and validated in GSE41571. In addition, we also found that the expression of CSF1R and PLAUR gradually increased with the accumulation of lipids and disease progression in cell and tissue experiments. Conclusion CSF1R and PLAUR are key hub genes of foam cells and may play an important role in the biological process of atherosclerosis. These results advance our understanding of the mechanism behind atherosclerosis and potential therapeutic targets for future development.

Role of the APOE polymorphism in carotid and lower limb revascularization: A prospective study from Southern Italy. PLoS One 2017; 12:e0171055. [PMID: 28249002 PMCID: PMC5332070 DOI: 10.1371/journal.pone.0171055] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2016] [Accepted: 01/14/2017] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Atherosclerosis is a complex multifactorial disease and the apolipoprotein E (APOE) polymorphism has been associated to vascular complications of atherosclerosis. OBJECTIVES To investigate the relationship between the APOE genotypes and advanced peripheral vascular disease. MATERIALS AND METHODS 258 consecutive patients (201 males and 57 females, mean age 70.83 ± 7.89 years) with severe PVD were enrolled in a 42-months longitudinal study (mean 31.65 ± 21.11 months) for major adverse cardiovascular events. At follow-up genotypes of the APOE polymorphism were investigated in blinded fashion. RESULTS As compared with ε3/ε3, in ε4-carriers a significant higher incidence of major adverse cardiovascular events (35.58% vs. 20.79%; p = 0.025) and total peripheral revascularization (22.64% vs. 5.06%; p < 0.001) was observed. Prospective analysis, showed that ε4-carriers have an increased hazard ratio for major adverse cardiovascular events (adjusted HR 1.829, 95% CI 1.017-3.287; p = 0.044) and total peripheral revascularization (adjusted HR = 5.916, 95% CI 2.405-14.554, p <0.001). CONCLUSIONS The ε4 allele seems to be risk factor for major adverse cardiovascular events, and in particular for total peripheral revascularization in patients with advanced atherosclerotic vascular disease.

Abstract
C-reactive protein (CRP), a phylogenetically highly conserved plasma protein, is the classical acute phase reactant in humans. Upon infection, inflammation, or tissue damage, its plasma level can rise within hours >1000-fold, providing an early, nonspecific disease indicator of prime clinical importance. In recent years, another aspect of CRP expression has attracted much scientific and public attention. Apart from transient, acute phase-associated spikes in plasma concentration, highly sensitive measurements have revealed stable interindividual differences of baseline CRP values in healthy persons. Strikingly, even modest elevations in stable baseline CRP plasma levels have been found to correlate with a significantly increased risk of future cardiovascular disease. These observations have triggered intense controversies about potential atherosclerosis-promoting properties of CRP. To directly assess potential effects of CRP on atherogenesis, we have generated CRP-deficient mice via gene targeting and introduced the inactivated allele into atherosclerosis-susceptible ApoE−/− and LDLR−/− mice, two well established mouse models of atherogenesis. Morphometric analyses of atherosclerotic plaques in CRP-deficient animals revealed equivalent or increased atherosclerotic lesions compared with controls, an experimental result, which does not support a proatherogenic role of CRP. In fact, our data suggest that mouse CRP may even mediate atheroprotective effects, adding a cautionary note to the idea of targeting CRP as therapeutic intervention against progressive cardiovascular disease.
