The microRNAs regulate the expression of multiple genes involved in diseases such as cancer, diabetes and cardiovascular disease. In this study, we have investigated the association between the miR-224 gene polymorphism (rs188519172A>G) and susceptibility of coronary artery disease CAD.
Hundred CAD patients and 100-matched healthy control were included. Genotyping of the miR-224 (rs188519172A>G) polymorphism was performed using Amplification refractory mutation system PCR method (ARMS-PCR).
A significant difference was observed in the genotype distribution among CAD patients and healthy controls (P=0.018). The frequencies of all three genotypes GG, GA, AA reported in the patient's samples were 33%, 66% and 01%, and in the healthy controls samples, were 16%, 82% and 2% respectively. A multivariate analysis based on logistic regression was conducted for each group to estimate the association between miR-224 rs188519172 genotypes and risk to coronary artery disease. Results show that the miR-224 (rs188519172 A>G) polymorphism was associated with a decreased risk to CAD in a codominant model, GA genotype vs. GG (OR = 0.39 (95 % CI, 0.19-0.76), RR 0.58 (0.38-0.90, P=0.006). In the dominant model, (GA+AA vs. GG), there was also a significant association with the OR=0.38 (95 % CI (0.19-0.76), RR 0.58 (0.38-0.89), and P=0.006. Whereas, in the recessive model, (GG+GA vs. AA), there was no significant association of CAD with OR=0.49 (95% CI (0.044-5.54), RR 0.74 (0.33-1.68), and P=0.48.
Our findings indicated that miR-224 (rs188519172) GA genotype is associated with a decreased susceptibility to CAD.
微小RNA调控多种与癌症、糖尿病和心血管疾病等疾病相关的基因表达。在本研究中，我们调查了miR - 224基因多态性（rs188519172A>G）与冠状动脉疾病（CAD）易感性之间的关联。
纳入100例CAD患者和100例匹配的健康对照。采用扩增阻滞突变系统PCR方法（ARMS - PCR）对miR - 224（rs188519172A>G）多态性进行基因分型。
CAD患者和健康对照的基因型分布存在显著差异（P = 0.018）。患者样本中报告的所有三种基因型GG、GA、AA的频率分别为33%、66%和1%，而在健康对照样本中分别为16%、82%和2%。对每组进行基于逻辑回归的多变量分析，以估计miR - 224 rs188519172基因型与冠状动脉疾病风险之间的关联。结果显示，在共显性模型中，miR - 224（rs188519172 A>G）多态性与CAD风险降低相关，GA基因型与GG基因型相比（比值比=0.39（95%置信区间，0.19 - 0.76），相对风险0.58（0.38 - 0.90），P = 0.006）。在显性模型中，（GA + AA与GG相比），也存在显著关联，比值比=0.38（95%置信区间（0.19 - 0.76），相对风险0.58（0.38 - 0.89），P = 0.006）。然而，在隐性模型中，（GG + GA与AA相比），CAD与比值比=0.49（95%置信区间（0.044 - 5.54），相对风险0.74（0.33 - 1.68），P = 0.48）无显著关联。
我们的研究结果表明，miR - 224（rs188519172）GA基因型与CAD易感性降低相关。
