Abstract
Objective: The renin–angiotensin system gene has been implicated in the progression of colorectal cancer. Nevertheless, the details of that role remain controversial. We performed a meta-analysis to investigate the correlation between renin–angiotensin system gene polymorphisms and colorectal cancer. Methods: We retrieved relevant studies from PubMed and Embase. Subsequently, fixed or random-effects models were used to calculate pooled odds ratios (ORs) with 95% confidence intervals (CIs). Results: We identified six studies of the angiotensin-converting enzyme insertion/deletion (I/D) polymorphism, and two studies of the angiotensinogen M235T polymorphism. The angiotensin-converting enzyme I/D polymorphism did not significantly correlate with colorectal cancer risk in the total population (DD vs. II: OR 0.77, 95% CI 0.39–1.50; DI vs. II: OR 1.05, 95% CI 0.85–1.30; dominant model: OR 0.94, 95% CI 0.68–1.31; recessive model: OR 1.01, 95% CI 0.80–1.27). Similarly, the angiotensinogen M235T polymorphism was not associated with colorectal cancer risk (TT vs. MM: OR 1.38, 95% CI 0.52–3.67; TM vs. MM: OR 1.19, 95% CI 0.96–1.47; dominant model: OR 1.28, 95% CI 0.77–2.14; recessive model: OR 1.17, 95% CI 0.53–2.59). Conclusion: Our findings suggest that the angiotensin-converting enzyme I/D and angiotensinogen M235T polymorphisms are unlikely to correlate with colorectal cancer.
目的:肾素-血管紧张素系统基因与结直肠癌的进展有关。然而,这一角色的细节仍存在争议。我们进行了一项荟萃分析,以调查肾素-血管紧张素系统基因多态性与结直肠癌之间的相关性。方法:我们从PubMed和Embase检索相关研究。随后,使用固定或随机效应模型计算95%置信区间(ci)的合并优势比(ORs)。结果:我们确定了6项血管紧张素转换酶插入/缺失(I/D)多态性研究和2项血管紧张素原M235T多态性研究。在总体人群中,血管紧张素转换酶I/D多态性与结直肠癌风险无显著相关性(DD vs II: OR 0.77, 95% CI 0.39-1.50;DI vs. II: OR 1.05, 95% CI 0.85-1.30;优势模型:OR 0.94, 95% CI 0.68-1.31;隐性模型:OR 1.01, 95% CI 0.80-1.27)。同样,血管紧张素原M235T多态性与结直肠癌风险无关(TT vs. MM: OR 1.38, 95% CI 0.52-3.67;TM vs. MM: OR 1.19, 95% CI 0.96-1.47;优势模型:OR 1.28, 95% CI 0.77-2.14;隐性模型:OR 1.17, 95% CI 0.53-2.59)。结论:血管紧张素转换酶I/D和血管紧张素原M235T多态性与结直肠癌的相关性不大。
期刊介绍:
JRAAS is a peer-reviewed, open access journal, serving as a resource for biomedical professionals, primarily with an active interest in the renin-angiotensin-aldosterone system in humans and other mammals. It publishes original research and reviews on the normal and abnormal function of this system and its pharmacology and therapeutics, mostly in a cardiovascular context but including research in all areas where this system is present, including the brain, lungs and gastro-intestinal tract.
