High-altitude pulmonary edema occurs most frequently in non-acclimatized low landers on exposure to altitude ≥2500 m. High-altitude pulmonary edema is a complex condition that involves perturbation of signaling pathways in vasoconstrictors, vasodilators, anti-diuretics, and vascular growth factors. Genetic variations are instrumental in regulating these pathways and evidence is accumulating for a role of epigenetic modification in hypoxic responses. This review focuses on the crosstalk between high-altitude pulmonary edema-associated genetic variants and transcription factors, comparing high-altitude adapted and high-altitude pulmonary edema-afflicted subjects. This approach might ultimately yield biomarker information both to understand and to design therapies for high-altitude adaptation.
高原肺水肿最常发生于未适应高原环境的低海拔居民暴露于海拔≥2500米的高度时。高原肺水肿是一种复杂的病症,涉及血管收缩剂、血管扩张剂、抗利尿剂和血管生长因子信号通路的紊乱。基因变异有助于调节这些通路,并且越来越多的证据表明表观遗传修饰在低氧反应中发挥作用。本综述聚焦于高原肺水肿相关基因变异与转录因子之间的相互作用,比较适应高原环境者和患高原肺水肿者。这种方法最终可能会产生生物标志物信息,以帮助理解和设计高原适应疗法。
