摘要
目的:本研究的目的是探讨基因多态性之间的关联在节律基因与阿尔茨海默病(AD)和/或晚发性抑郁症(LOD)。阿尔茨海默病的病理导致昼夜节律紊乱,对生活质量有明显的负面影响。此外,有越来越多的证据表明,昼夜节律系统的监管机构对阿尔茨海默病和晚发性抑郁症病理。 设计主题:一个探索性的病例对照研究,旨在评估样本在PER2, PER3, CLOCK和 OX2R 基因上的SNPs。样本在由249 例阿尔茨海默病患者,222名晚发性抑郁症和112名健康人组成。 措施:参与者使用DSM-IV标准评价晚发性抑郁症, NINCDS-ADRDA评价阿尔茨海默病。 结果:等位基因分析,OX2R SNP和 rs2134294基因,显示与晚发性抑郁症的C等位基因(P = 0.02,或= 1.6)和阿尔茨海默病(P = 0.04,或= 1.5)的关联。rs2134294也表明基因型关联的C / C(P = 0.01)与对照组相比有高风险发展晚发性抑郁症,有2.7%少见比例。rs9370399(OX2R)也显示之间的等位基因(P = 0.03,或= 1.4)和阿尔茨海默病相关。这些结果不考虑考1000以后的置换试验。对于OX2R的其他标记和所有其他标志物基因研究没有发现关联关系。 结论:总之,本研究发现了生物钟基因(Per2,PER3,时钟和OX2R)基因多态性与晚发性抑郁症或阿尔茨海默病不相关。

摘要: Objectives: This study aims to evaluate the association between polymorphisms in circadian genes and Alzheimer’s disease (AD) and/or late-onset depression (LOD). AD pathology leads to circadian disturbances, with clear negative influence on quality of life. In addition, there is an increasing evidence that regulators of circadian system have effects on AD and LOD pathology.
Design and Subjects: An exploratory case-control study designed to evaluate SNPs in the PER2, PER3, CLOCK and OX2R genes in a sample composed by 249 AD, 222 LOD and 112 healthy individuals.
Measures: The participants were evaluated using DSM-IV criteria for LOD and NINCDS-ADRDA for AD.
Results: In allelic analysis, the OX2R SNP, rs2134294, showed an association of allele C with LOD (p =0.02, OR= 1.6) and AD (p=0.04, OR =1.5). The rs2134294 also showed a genotypic association C/C (p =0.01) for higher risk to develop LOD compared to the control group, with an odd’s ratio of 2.7. The rs9370399 (OX2R) has also shown an association between A allele (p=0.03, OR= 1.4) and AD. These results do not persist after a 1,000 permutations test. For other markers of the OX2R gene and for all other markers of this study no association was found.
Conclusion: In conclusion, the present study found that the investigated Circadian Genes (PER2, PER3, CLOCK and OX2R) polymorphisms were not associated with LOD or AD.
