与肺功能相关的蛋白质生物标志物可能会影响心血管疾病风险. 整体蛋白α1β1和其他蛋白质显示出在慢性阻塞性肺病和心脏病中未来干预的潜力.
科学领域:
- 生物化学和分子生物学
- 心血管医学 心血管医学
- 肺部病理学 肺部病理学
背景情况:
- 肺功能与心血管疾病 (CVD) 风险有关,但机制尚未完全理解.
- 识别蛋白质生物标志物可以阐明这些联系,并为风险评估提供信息.
研究的目的:
- 确定与肺功能相关的蛋白质生物标志物 (1秒内强制呼气体积和强制生命能力).
- 检查这些蛋白质对发生慢性阻塞性肺病 (COPD),冠心病 (CHD),心力衰竭 (HF) 和全因死亡率的影响.
主要方法:
- 对白人和黑人美国人的前性队列数据的分析 (社区动脉样硬化风险研究).
- 蛋白质-肺功能关联的线性回归;逻辑回归和Cox模型用于结果预测.
- 路径丰富和门德尔随机化来探索生物功能和因果关系.
主要成果:
- 364种蛋白与肺功能相关 (p<0.05).
- 112种蛋白与所有四种结果相关;86种增加风险 (OR/HR 1.05-1.42),26种降低风险 (OR/HR 0.69-0.96).
- 包括整合素α1β1在内的六种蛋白质显示出潜在的逆因果作用;整合素α1β1与降低了COPD,CHD和HF风险有关.
结论:
- 与肺功能相关的蛋白质可能在心血管疾病风险中起作用.
- 六种蛋白质,特别是整合素α1β1,是未来治疗干预的有希望的目标.
