In humans, evidence about the association between levels of monocyte chemoattractant protein-1 (MCP-1), its coding gene chemokine (C-C motif) ligand 2 (CCL2), and risk of coronary artery disease (CAD) is contradictory.
We performed a nested case-control study in the prospective EPIC-Norfolk cohort investigating the relationship between CCL2 single-nucleotide polymorphisms (SNPs), MCP-1 concentrations, and the risk of future CAD. Cases (n=1138) were apparently healthy men and women aged 45 to 79 years who developed fatal or nonfatal CAD during a mean follow-up of 6 years. Controls (n=2237) were matched by age, sex, and enrollment time. Using linear regression analysis no association between CCL2 SNPs and MCP-1 serum concentrations became apparent, nor did we find a significant association between MCP-1 serum levels and risk of future CAD. Finally, Cox regression analysis showed no significant association between CCL2 SNPs and the future CAD risk. In addition, we did not find any robust associations between the CCL2 haplotypes and MCP-1 serum concentration or future CAD risk.
Our data do not support previous publications indicating that MCP-1 is involved in the pathogenesis of CAD.
在人类中,关于单核细胞趋化蛋白-1(MCP-1)水平与其编码基因趋化因子(C-C 基序)配体 2(CCL2)与冠心病(CAD)风险之间的关联的证据存在矛盾。
我们在前瞻性 EPIC-Norfolk 队列中进行了一项巢式病例对照研究,调查了 CCL2 单核苷酸多态性(SNP)、MCP-1 浓度与未来 CAD 风险之间的关系。病例(n=1138)为年龄在 45 至 79 岁之间、在平均 6 年的随访期间发生致命或非致命 CAD 的健康男性和女性。对照组(n=2237)按年龄、性别和入组时间匹配。使用线性回归分析,我们没有发现 CCL2 SNP 与 MCP-1 血清浓度之间存在关联,也没有发现 MCP-1 血清水平与未来 CAD 风险之间存在显著关联。最后,Cox 回归分析显示 CCL2 SNP 与未来 CAD 风险之间没有显著关联。此外,我们没有发现 CCL2 单倍型与 MCP-1 血清浓度或未来 CAD 风险之间存在任何可靠的关联。
我们的数据不支持先前的出版物,即 MCP-1 参与 CAD 的发病机制。
