摘要:

目的 采用两样本孟德尔随机化(MR)分析,探讨甾醇酯与肝内导管、胆道和胆囊恶性肿瘤发生的因果关联,为甾醇酯的生物学机制研究以及探索肝内导管、胆道和胆囊恶性肿瘤的早期防治提供依据。 方法 15种不同种类的甾醇酯特征的工具变量数据来自芬兰数据库(FinnGen),肝内导管、胆道和胆囊恶性肿瘤全基因组数据来自全基因组关联研究(GWAS)数据库,以甾醇酯、肝内导管、胆道和胆囊恶性肿瘤为关键词进行检索,下载编号为ICD-O-3和GCST90277238-GCST9027725,采用逆方差加权法(IVW)、MR-Egger回归法和加权中位数(WM)法评价甾醇酯与肝内导管、胆道和胆囊恶性肿瘤发生的因果关联,采用MR-Egger截距法进行多效性检验,Cochran Q检验进行异质性检验,留一法进行敏感性分析,综合评估结果的可靠性和稳健性。 结果 IVW分析,甾醇酯(27:1/14:0)[比值比(OR)=2.349,95%置信区间(CI)=1.371~4.025,P=0.002]、甾醇酯(27:1/16:0)(OR=1.248,95%CI=1.018~1.523,P=0.033)、甾醇酯(27:1/18:2)(OR=1.361,95%CI=1.078~1.718,P=0.009)和甾醇酯(27:1/22:6)(OR=1.339,95%CI=1.001~1.791,P=0.049)增加患肝内导管、胆道和胆囊恶性肿瘤的风险。MR-Egger回归分析,甾醇酯(27:1/18:2)(OR=2.038,95%CI=1.337~3.105,P=0.011)是肝内导管、胆道和胆囊恶性肿瘤的危险因素。WM分析,甾醇酯(27:1/14:0)(OR=2.786,95%CI=1.419~5.468,P=0.003),甾醇酯(27:1/18:2)(OR=1.548,95%CI=1.148~2.088,P=0.004)是肝内导管、胆道和胆囊恶性肿瘤的危险因素。MR-Egger截距分析和Cochran Q检验,本研究无水平多效性和异质性。留一法敏感性分析未发现影响较大的异常单核苷酸多态性(SNPs),确保本研究可靠性。 结论 甾醇酯(27:1/14:0)、甾醇酯(27:1/16:0)、甾醇酯(27:1/18:2)和甾醇酯(27:1/22:6)与肝内导管、胆道和胆囊恶性肿瘤之间存在因果关联且促进该类恶性肿瘤的发生发展。

Abstract:

Objective To discuss the causal association between sterol esters and intrahepatic duct, biliary tract, and gallbladder malignancies using two-sample Mendelian randomization (MR) analysis, and to clarify the biological mechanisms of sterol esters, and to provide the a basis for early prevention and treatment of these malignancies. Methods The instrumental variable data for 15 different types of sterol ester traits were obtained from the Finnish database (FinnGen). The genome-wide association study (GWAS) data for intrahepatic duct, biliary tract, and gallbladder malignancies were retrieved from the GWAS database using the keywords “sterol ester” and “intrahepatic duct, biliary tract, and gallbladder malignancies”(accession numbers: ICD-O-3 and GCST90277238-GCST9027725). The inverse-variance weighted (IVW) method, MR-Egger regression, and weighted median (WM) method were used to assess the causal association between sterol esters and the risk of these malignancies. Pleiotropy was tested using the MR-Egger intercept method; heterogeneity was evaluated using Cochran’s Q test; and sensitivity analysis was performed using the leave-one-out approach to comprehensively assess the reliability and robustness of the results. Results The IVW analysis results showed that Sterol ester (27:1/14:0) odds ratio(OR)=2.349, 95% confidence interval (CI)=1.371-4.025, P=0.002), Sterol ester(27:1/16:0) (OR=1.248, 95%CI=1.018-1.523, P=0.033), Sterol ester (27:1/18:2) (OR=1.361, 95%CI=1.078-1.718, P=0.009), and Sterol ester (27:1/22:6) (OR=1.339, 95%CI=1.001-1.791, P=0.049) were associated with an increased risk of intrahepatic duct, biliary tract, and gallbladder malignancies. The MR-Egger regression analysis results indicated that Sterol ester (27:1/18:2) (OR=2.038, 95%CI=1.337-3.105, P=0.011) was a risk factor for these malignancies. The WM analysis results revealed that Sterol ester (27:1/14:0) (OR=2.786, 95%CI=1.419-5.468, P=0.003) and Sterol ester (27:1/18:2) (OR=1.548, 95%CI=1.148-2.088, P=0.004) were also risk factors. The MR-Egger intercept analysis and Cochran’s Q test results indicated no significant horizontal pleiotropy or heterogeneity. The leave-one-out sensitivity analysis did not identify any influential outlier single nucleotide polymorphism (SNPs), confirming the reliability of the study. Conclusion Sterol ester (27:1/14:0), Sterol ester (27:1/16:0), Sterol ester (27:1/18:2), and Sterol ester (27:1/22:6) exhibit causal associations with intrahepatic duct, biliary tract, and gallbladder malignancies and may promote their development.
