Published researches have suggested some associations between PPAR-γ and ischemic stroke (IS) development. This meta-analysis was conducted to evaluate the association between PPAR-γ gene polymorphisms and IS risk.
A systematic search was conducted in PubMed, Embase, Web of Science, China National Knowledge Infrastructure, and WanFang databases. The pooled association of odd ratios (ORs) and its 95% confidence interval (CI) was calculated to assess the IS risk of PPAR-γ rs1801282 C/G and rs3856806 C/T polymorphisms. Furthermore, the heterogeneity test, cumulative analyses, sensitivity analyses, and publication bias were conducted.
Sixteen publications with 3786 cases and 5343 controls were identified. Overall findings indicated that rs1801282 C/G polymorphism may be associated with an increased risk for IS (GG vs. CC: OR = 2.17 95%CI = 1.09-4.35, p = .03, I = 0%; GG vs. CC+CG: OR = 2.15, 95%CI = 1.07-4.32, p = .03, I = 0%). The similar results were also found in the subgroup analysis. In addition, no significant association was observed between rs3856806 C/T polymorphism and IS risk.
In conclusion, our study showed that PPAR-γ rs1801282 C/G polymorphism probably plays an important role in IS occurrence. The result should be verified with more studies in the future.
已发表的研究表明,过氧化物酶体增殖物激活受体-γ(PPAR-γ)与缺血性脑卒中(IS)的发展之间存在某些关联。本荟萃分析旨在评估 PPAR-γ 基因多态性与 IS 风险之间的关系。
系统检索了 PubMed、Embase、Web of Science、中国知网和万方数据库,计算比值比(OR)及其 95%置信区间(CI)的合并值,以评估 PPAR-γ rs1801282 C/G 和 rs3856806 C/T 多态性与 IS 风险的关系。此外,还进行了异质性检验、累积分析、敏感性分析和发表偏倚分析。
共纳入 16 项研究,包含 3786 例病例和 5343 例对照。总体结果表明,rs1801282 C/G 多态性可能与 IS 风险增加相关(GG 与 CC:OR=2.17,95%CI=1.09-4.35,p=0.03,I=0%;GG 与 CC+CG:OR=2.15,95%CI=1.07-4.32,p=0.03,I=0%)。亚组分析也得到了类似的结果。此外,rs3856806 C/T 多态性与 IS 风险之间未见显著关联。
综上所述,本研究表明,PPAR-γ rs1801282 C/G 多态性可能在 IS 发生中起重要作用。该结果有待未来更多研究加以验证。
