【摘要】 目的探讨成纤维细胞生长因子1(FGF-1)基因启动子多态性是否与晚发型阿尔茨海默病(LOAD)相关。方法收集206例尸体检查的样本,包括100例LOAD和年龄匹配的对照组106例。PCRRFLP(Restrictionfragmentlengthpolymorphism)法分析FGF1基因启动子(-1385A/G)的基因型。结果FGF1基因启动子(-1385A/G)的基因型频率分布是:AA型20例(10%),GA型89例(43%),GG型97例(47%),在LOAD组和对照组之间,不同基因型频率分布有显著性差异(P=0.027);GG基因型与LOAD呈正相关(oddsratio=2.02,95%CI:1.16～3.52)。结论FGF1基因启动子(-1385A/G)多态性与LOAD显著相关。更多还原

【Abstract】 ObjectiveTo evaluate the correlation between the promoter polymorphism of Fibroblast Growth Factor 1 (FGF-1) and late-onset Alzheimer’s disease (LOAD). MethodsClinic pathological data from 206 autopsies were analyzed, including 100 autopsy-confirmed LOAD patients and 106 age-matched non-demented controls. PCR-RFLP (Restriction fragment length polymorphism) approach was used to determine the genotype of the promoter polymorphism of FGF-1 gene. ResultsThe genotyping frequencies of the promoter polymorphism (-1385 A/G) were AA 20 (10%), GA 89 (43%), GG 97 (47%), respectively. There was significant (P=0.027) difference of genotyping frequencies between the cases and controls; GG genotype was positively associated with LOAD (odds ratio=2.02, 95%CI:1.16~3.52). ConclusionThe promoter polymorphism (-1385 A/G) of FGF-1 gene was associated with LOAD.更多还原
