甲基化风险评分 (MRS) 与患2型糖尿病 (T2DM) 的风险更高有关. 吸烟和高血压等环境因素可能与MRS相互作用,影响T2DM风险.
科学领域:
- 遗传学和表观遗传学
- 代谢疾病 代谢疾病
- 环境健康 环境健康
背景情况:
- 2型糖尿病 (T2DM) 是一种复杂的代谢障碍,具有重大公共卫生影响.
- 表观遗传修饰,如DNA甲基化,越来越多地被认为是T2DM病原体的贡献者.
- 整合多个CpG站点的甲基化风险评分 (MRS) 可能为评估T2DM风险提供一种新的方法.
研究的目的:
- 调查甲基化风险评分 (MRS) 与患2型糖尿病 (T2DM) 的风险之间的关联.
- 探索MRS与T2DM发展中的环境风险因素之间的潜在相互作用.
主要方法:
- 使用嵌套病例控制研究设计,对241例T2DM病例和241个匹配的对照进行了研究.
- 条件后勤回归确定了MRS建设的风险CpG站点.
- 使用四个T2DM相关基因 (ABCG1,FTO,KCNV1,TXNIP) 的甲基化数据计算了简单和加权的MRS.
- 分层分析检查了MRS和环境因素 (吸烟,高血压,肥胖) 之间的相互作用.
主要成果:
- 简单和加权MRSs的升高三角形显着与增加T2DM风险相关 (ORs在2.39至2.59).
- 每增加MRS的标准偏差都与T2DM风险增加1.60-1.66倍有关.
- 在MRS和T2DM风险之间观察到J形关联.
- 在MRS和环境因素之间发现了显著的相互作用,包括吸烟,高血压和肥胖,T2DM风险 (P相互作用<0.05).
结论:
- 较高的甲基化风险得分 (MRS) 与2型糖尿病 (T2DM) 的风险增加有关.
- 环境因素在调节表观遗传标记和T2DM易感性之间的关系方面发挥着至关重要的作用.
