BACKGROUND/AIMS: To accurately evaluate the impact of the C/T polymorphism in microRNA (miRNA)-196a2 on the colorectal cancer (CRC) risk, by meta-analysis.
An electronic search for articles was conducted in PubMed, EMBASE, ISI Web of Science, and the Cochrane Library. The pooled odds ratio (OR) and its 95% confidence interval (CI) were used to assess the association through meta-analysis.
5 studies were used for analysis. The results showed a significant association between the miRNA-196a2 C/T polymorphism and CRC risk in the genetic models (C vs. T: OR = 1.168, 95% CI = 1.106-1.282, p = 0.001; CC vs. TT: OR = 1.368, 95% CI = 1.132-1.654, p = 0.001; TC/CC vs. TT: OR = 1.206, 95% = CI 1.035-1.405, p = 0.016; CC vs.
TC/TT: OR = 1.254, 95% CI = 1.077-1.461, p = 0.004), with the exception of the TC-versus-TT model (TC vs. TT: OR = 1.130, 95% CI = 0.961-1.329, p = 0.138). In a subgroup analysis based on ethnicity, we identified a significant overrepresentation of the polymorphism in individuals of Asian ethnicity.
This meta-analysis indicates a significant association between the miRNA-196a2 polymorphism and CRC risk.
背景/目的:通过荟萃分析准确评估微小RNA(miRNA)-196a2中C/T多态性对结直肠癌(CRC)风险的影响。
在PubMed、EMBASE、ISI科学网和Cochrane图书馆中进行电子文献检索。通过荟萃分析,使用合并优势比(OR)及其95%置信区间(CI)来评估关联性。
5项研究用于分析。结果显示,在遗传模型中,miRNA-196a2 C/T多态性与CRC风险之间存在显著关联(C与T:OR = 1.168,95%CI = 1.106 - 1.282,p = 0.001;CC与TT:OR = 1.368,95%CI = 1.132 - 1.654,p = 0.001;TC/CC与TT:OR = 1.206,95%CI = 1.035 - 1.405,p = 0.016;CC与TC/TT:OR = 1.254,95%CI = 1.077 - 1.461,p = 0.004),TC与TT模型除外(TC与TT:OR = 1.130,95%CI = 0.961 - 1.329,p = 0.138)。在基于种族的亚组分析中,我们发现该多态性在亚洲种族个体中显著过度呈现。
这项荟萃分析表明miRNA-196a2多态性与CRC风险之间存在显著关联。
