摘要

背景:问题性酒精使用(PAU)是一个严重的全球健康问题,治疗方案有限。尽管遗传学研究已经确定了与PAU相关的基因组区域,但具体的致病基因和蛋白质仍不清楚。本研究旨在通过整合不同的遗传和分子数据来识别这些致病基因,从而为更好的治疗策略提供信息。方法:采用孟德尔随机化(Mendelian randomisation, MR)方法,将遗传数据与脑组织和血液组织中的基因活性相结合,鉴定可能导致PAU的基因和蛋白质。多个统计测试证实了表达与PAU之间共享的遗传信号。我们还研究了它们对其他性状的影响以及与现有药物的潜在相互作用。研究结果:我们通过MR鉴定出97个基因和13个蛋白可能在PAU中起因果作用,并且在脑组织中富集。在Bonferroni校正后,这些关联仍然显著,并进一步得到共定位分析(假设后验概率为4 > 0.75)和多个数据集的一致性的支持。一些靶点也显示出与PAU对其他健康结果的一致影响,在全现象分析中得到bonferroni显著关联的支持,表明药物再利用的潜力。解释:这项研究强调了脑和血液组织中可能有助于PAU发展的分子特征。综合多组学分析揭示了神经和外周系统之间共享的生物通路,这表明开发具有良好安全性的多系统干预措施的潜力。资金:本研究由三星研究基金,成均馆大学,2023年支持。

Identification of potential therapeutic targets for problematic alcohol use using multi-omics data.

Background: Problematic alcohol use (PAU) is a serious global health issue with limited treatment options. Although genetic studies have identified genomic regions associated with PAU, the specific causal genes and proteins remain unclear. This study aimed to identify these causal genes by integrating diverse genetic and molecular data to inform better treatment strategies.

Methods: We used Mendelian randomisation (MR) to identify genes and proteins that may cause PAU by combining genetic data with gene activity in brain and blood tissues. Multiple statistical tests confirmed shared genetic signals between expression and PAU. We also examined their effects on other traits and potential interactions with existing drugs.

Findings: We identified 97 genes and 13 proteins that are likely to play a causal role in PAU through MR, with strong enrichment in brain tissues. These associations remained significant after Bonferroni correction and were further supported by colocalisation analyses (posterior probability of hypothesis 4 > 0.75) and consistency across multiple datasets. Some targets also showed concordant effects with PAU on other health outcomes, supported by Bonferroni-significant associations in phenome-wide analyses, suggesting potential for drug repurposing.

Interpretation: This study highlights molecular signatures in both brain and blood tissues that may contribute to the development of PAU. Integrative multi-omics analyses revealed shared biological pathways across neural and peripheral systems, suggesting the potential for developing multi-systemic interventions with favourable safety profiles.

Funding: This study was supported by Samsung Research Fund, Sungkyunkwan University, 2023.

期刊介绍: eBioMedicine is a comprehensive biomedical research journal that covers a wide range of studies that are relevant to human health. Our focus is on original research that explores the fundamental factors influencing human health and disease, including the discovery of new therapeutic targets and treatments, the identification of biomarkers and diagnostic tools, and the investigation and modification of disease pathways and mechanisms. We welcome studies from any biomedical discipline that contribute to our understanding of disease and aim to improve human health.
