摘要:


文题释义:
组织蛋白酶:是在各种动物组织的细胞内(特别是溶酶体部分)发现的一类蛋白酶,是半胱氨酸蛋白酶家族的主要成员。截至目前,生物界中已发现至少28种组织蛋白酶,人体中已明确鉴定出15种,它们与人类肿瘤、骨质疏松、关节炎等多种重大疾病密切相关。
脑卒中:指脑血管发生破裂或意外阻塞而导致的急性脑损伤,引起损伤或坏死脑组织所支配的躯体功能异常表现的疾病。脑卒中的发作与年龄因素、生活习惯因素、药物因素、原发疾病因素等有关。

背景:研究证实组织蛋白酶与脑卒中之间存在关联,然而二者的因果关系尚不确定。
目的:使用孟德尔随机化分析评估组织蛋白酶与脑卒中之间的因果关系。
方法:组织蛋白酶数据来源于INTERVAL研究,脑卒中数据来源于GWAS数据库(由美国国家人类基因组研究学会和欧洲生物信息学研究所联合开发),通过单变量和多变量孟德尔随机化方法,探讨不同类型的组织蛋白酶对脑卒中及其亚型发病风险的因果关系,采用逆方差加权法作为评估因果关联效应的主要方法,采用加权中位数法和MR-Egger回归来评估结果的可靠性和稳定性。
结果与结论:①单变量孟德尔随机分析表明,较高的组织蛋白酶S水平对心源性栓塞性脑卒中的发生具有抑制作用(OR=0.901,95%CI:0.832-0.976,P=0.010),然而上述因果关系在反向孟德尔随机化分析中未达到统计学显著性。反向孟德尔随机分析表明,心源性栓塞性脑卒中可能导致组织蛋白酶L2水平下降(P=0.020,OR=0.984,95%CI:0.972-0.998),但该结果在多变量分析中未呈现统计学意义。一项使用9种组织蛋白酶作为变量的多变量分析显示,组织蛋白酶F水平升高会增加全因脑卒中和缺血性脑卒中的发病风险(OR=4.667,95%CI=1.000-21.782,P=0.050;OR=4.771,95%CI:1.044-21.804,P=0.044)。排除可能存在的混杂因素后,孟德尔随机化分析仍然显示组织蛋白酶F有潜力成为脑卒中的风险预测血清生物标志物。②研究主要基于国际数据库和欧洲人群数据进行分析,结果可为中国大型队列研究提供参考,为中国开展精准医学研究提供技术支持。然而,在借鉴过程中需注意中国人群的遗传背景、环境因素和生活方式等差异,开展符合中国人群特点的生物医学研究。

Abstract: BACKGROUND: Prior research has indicated a correlation between cathepsins and stroke, but the nature of this relationship—whether causal—has yet to be established. 
OBJECTIVE: To scrutinize the potential causal links between cathepsins and stroke using the Mendelian randomization method. 
METHODS: Leveraging summary statistics from genome-wide association studies (GWAS, developed jointly by the U.S. National Human Genome Research Institute and the European Bioinformatics Institute), we performed Mendelian randomization analyses using both univariable and multivariable approaches to investigate the causal associations of various cathepsin types with stroke risk and its specific subtypes. The inverse variance weighting method was used as the main method to assess the causal association effect, and the weighted median method and MR-Egger regression were used to assess the reliability and stability of the results.
RESULTS AND CONCLUSION: (1) The univariable Mendelian randomization analysis revealed that elevated Cathepsin S levels were associated with a reduced likelihood of cardioembolic stroke (odds ratio [OR]=0.901, 95% confidence interval [CI]: 0.832-0.976, P=0.010). However, this causal effect was not corroborated in the reverse Mendelian randomization analysis. The reverse Mendelian randomization analysis suggested that Cathepsin E Subtype (CES) could contribute to lower Cathepsin L2 levels (P=0.020, OR = 0.984, 95% CI=0.972-0.998), yet this finding lacked statistical significance in the multivariable context. A multivariable analysis, incorporating nine cathepsin types, indicated that elevated Cathepsin F levels were associated with an increased risk of all-cause stroke and ischemic stroke (OR=4.667, 95% CI=1.000-21.782, P=0.050, OR=4.771, 95% CI=1.044-21.804, P=0.044). Even after accounting for potential confounding factors, the Mendelian randomization analysis indicated that Cathepsin F holds promise as a serum biomarker for predicting stroke risk. (2) This study is primarily based on the analyses of international databases and European population data, which can serve as a reference for large-scale cohort studies in China and provide technical insights for the development of precision medicine research in China. However, it is essential to consider the differences in genetic background, environmental factors, and lifestyle among the Chinese population, and to conduct biomedical research that aligns with the unique characteristics of Chinese individuals.
