摘要:


文题释义:
孟德尔随机化:是一种新的流行病学研究方法,通过使用遗传决定因素(暴露的工具变量)评估风险因素与疾病关联的因果关系。该方法与临床随机对照试验中的随机分组相似,并且最大限度地减少了因为环境混杂因素和反向因果关系干扰而导致的结果偏倚。
肺动脉高压:以肺血管阻力增加导致肺动脉压力升高为特征,是一种危及生命的肺循环疾病。

背景:动脉型肺动脉高压是一种破坏性心肺疾病,尚无法根治。有研究表明血浆蛋白与动脉型肺动脉高压之间存在关联,但其中的因果关系未得到具体阐明。
目的:运用两样本孟德尔随机化方法,阐明血浆蛋白质组与动脉型肺动脉高压之间的因果关系,寻找动脉型肺动脉高压的潜在治疗靶点。
方法:从冰岛数据库中获取35 559名冰岛人的4 907个适配体测量的血浆蛋白全基因组关联分析统计数据;从R9版Finn Gen数据库中获取动脉型肺动脉高压的全基因组关联分析统计数据,包括234例病例和265 626例对照。利用孟德尔随机化和贝叶斯共定位分析方法进行分析,使用敏感性分析对研究结果进行检验,并构建蛋白-蛋白互作网络图,探索血浆蛋白与动脉型肺动脉高压的因果关系。
结果与结论:①逆方差加权法、最大似然法和Wald比率法结果显示有19种蛋白与动脉型肺动脉高压存在因果关系(P < 0.05),其中MFNG(OR=0.12,95%CI 0.02-0.61,P=0.01)、IFNAR1(OR=0.45,95%CI 0.24-0.84,P=0.012)等10种蛋白可能与动脉型肺动脉高压风险降低相关;GXYLT1(OR=3.48,95%CI 1.51-8.00,P=0.003)、PLG(OR=42.78,95%CI 2.49-734.31,P=0.01)等9种蛋白与动脉型肺动脉高压风险升高相关。运用错误发现率校正后,19种蛋白仍与动脉型肺动脉高压显著相关。②MR-Egger截距检验法、留一法等多项敏感性分析显示研究结果不存在水平多效性和异质性,说明研究结果的稳定性。③贝叶斯共定位分析结果显示,有PLG6(PPH4=1.0)、GXYLT1(PPH4=0.94)等6种血浆蛋白的PPH4 > 0.8,说明血浆蛋白和动脉型肺动脉高压全基因组关联研究在遗传关联方面具有相似的因果方差。④通过构建蛋白-蛋白互作网络图,发现PLG、Annexin A1、FGG、MMP7为核心蛋白。⑤文章采用孟德尔随机化的分析方法揭示了4 907种血浆蛋白与动脉型肺动脉高压之间潜在的因果关联,提示血浆蛋白可能是动脉型肺动脉高压的潜在治疗靶点,研究中发现的核心蛋白也为进一步深入研究动脉型肺动脉高压的病理生理机制提供了理论依据;其次使用冰岛和FinnGen大规模的国际数据库进行分析,为动脉型肺动脉高压在特定人群和环境中提供了新的研究方向与治疗思路,同时也为中国防治动脉型肺动脉高压提供了可借鉴的思路与方法。

Abstract: BACKGROUND: Pulmonary arterial hypertension is a destructive cardiopulmonary disease for which there is no cure. An association between plasma proteins and pulmonary arterial hypertension has been suggested, but the causal relationship has not been specifically elucidated. 
OBJECTIVE: To elucidate the causal relationship between plasma proteome and pulmonary arterial hypertension using a two-sample Mendelian randomization method, thereby searching for potential therapeutic targets for pulmonary arterial hypertension.
METHODS: Plasma Protein Gene-Wide Association Analysis Statistics for 4 907 Aptamer Measurements in 35 559 Icelanders from the Icelandic Database; Genome-wide association analysis statistics for pulmonary arterial hypertension were obtained from the Finn Gen database, version R9, including 234 cases and 265 626 controls. Analyses were performed using Mendelian randomization and Bayesian co-localization analysis, the findings were examined using sensitivity analyses, and protein-protein interaction network maps were constructed to explore the causal relationship between plasma proteins and pulmonary arterial hypertension.
RESULTS AND CONCLUSION: (1) The results of inverse variance weighting, maximum likelihood and Wald ratio methods showed 19 proteins causally associated with pulmonary arterial hypertension (P < 0.05). Among them, 10 plasma proteins, including Beta-1,3-N-acetylglucosaminyltransferase manic fringe (odds ratio [OR]=0.12, 95% confidence interval [CI] 0.02-0.61, P=0.01) and interferon alpha/beta receptor 1 (OR=0.45, 95% CI 0.24-0.84, P=0.012), might be associated with a reduced risk of pulmonary arterial hypertension. In contrast, nine plasma proteins, such as glucoside xylosyltransferase 1 (OR=3.48, 95% CI 1.51-8.00, P=0.003) and plasminogen (OR=42.78, 95% CI 2.49-734.31, P=0.01), might be associated with an increased risk of pulmonary arterial hypertension. After the false discovery rate was corrected, 19 proteins remained significantly associated with pulmonary arterial hypertension. (2) Multiple sensitivity analyses such as the MR-Egger intercept test and leave-one-out method showed no horizontal multiplicity or heterogeneity in the results of the study, indicating the stability of the study’s results. (3) Bayesian co-localization analysis showed that six plasma proteins, including plasminogen (PPH4=1.0) and glucoside xylosyltransferase 1 (PPH4=0.94), had PPH4 > 0.8, suggesting that plasma proteins and the genome-wide association study of pulmonary arterial hypertension had similar causal variance in terms of genetic association. (4) By constructing a protein-protein interaction network map, plasminogen, Annexin A1, fibrinogen gamma chain and matrix metalloproteinase 7 were found to be core proteins. (5) The article used Mendelian randomization analysis to reveal a potential causal association between 4 907 plasma proteins and pulmonary arterial hypertension, suggesting that plasma proteins may be potential therapeutic targets for pulmonary arterial hypertension. The core proteins identified in the study also provide a theoretical basis for further in-depth study of the pathophysiological mechanisms of pulmonary arterial hypertension. Secondly, analyses using the large-scale international databases of Iceland and FinnGen provide new research directions and treatment ideas for pulmonary arterial hypertension in specific populations and environments, as well as ideas and methods that can be used to prevent and treat pulmonary arterial hypertension in China.
