摘要:



文题释义:
单细胞测序:是对单个细胞的基因组、转录组、表观组或蛋白质组进行高分辨率分析的技术,突破传统群体细胞测序的“平均化”局限,揭示细胞异质性和稀有细胞类型的功能。
多组学研究:单细胞测序与数量性状位点数据的整合,将遗传关联研究从“组织水平”推进到“细胞-分子机制”层面,解决了复杂疾病遗传架构的异质性和环境依赖性难题。未来随着单细胞多组学技术和计算方法的突破,这一策略有望成为解析疾病机制、开发精准疗法的核心范式。

背景:随着中国老龄化进程的加快,骨质疏松症患者也逐渐增多,而全基因组关联研究和单细胞转录测序的发展使得研究者们可通过将各组学研究数据相结合以发现更多与骨质疏松症相关的基因。
目的:通过整合亚洲、欧洲人群的全基因组关联研究和转录组学,基于汇总统计数据的孟德尔随机化拓展骨质疏松症新的治疗靶点。
方法:通过整合来自多个组织(血液、肌肉-骨骼)的顺式表达数量性状位点和蛋白质数量性状位点数据集(基因-组织表达项目组V.8选取了人类血液与骨骼-肌肉两种组织的表达数量性状位点数据集,基因-组织表达项目组是研究基因表达在不同组织/器官中变异及其与遗传调控关系的大型国际合作项目)及骨质疏松症全基因组关联研究数据(FinnGen数据库2021年发布的关于欧洲人种骨质疏松症的全基因组关联研究数据,FinnGen是芬兰的一个大型基因组研究项目;从日本生物银行数据库获取的2020年发布关于东亚人群的大规模全基因组关联研究,是日本主导的大规模人群队列研究项目,使用基于汇总统计数据的孟德尔随机化方法来鉴定骨质疏松症的相关基因,并使用共定位分析、单细胞测序及富集分析对已鉴定出的相关基因做进一步分析。所有数据均来自于已发表的研究或公开可用的数据,均已提供伦理审批书和知情同意书。
结果与结论:①基于汇总统计数据的孟德尔随机化分析一共确定了64个(去除重复基因后)与骨质疏松症显著相关的基因,其中人类白细胞抗原(HLA)等位基因HLA-DQA1、HLA-DQA2、HLA-DQB1、HLA-DQB2和HLA-DRB5在2个结局数据集中得到了相互验证,具有显著相关性;②进一步的共定位分析表明,HLA-DQA2、HLA-DQB1具有共定位的证据(后验概率PPH4>0.8);③蛋白质数量性状位点分析结果表明,血浆中高水平的HLA-DQA2与骨质疏松症风险降低相关;④在单细胞测序分析方面,在骨质疏松症的免疫微环境中,树突状细胞、B细胞、巨噬细胞和中性粒细胞丰度较其他细胞群明显升高;⑤富集分析结果表明,鉴定出的基因在组织相容性复合物Ⅱ分子抗原呈递途径富集;⑥此次研究通过生物信息学结合亚洲、欧洲人群的全基因组关联数据,初步确定了几个以前尚未报道过的与骨质疏松症相关的基因,研究者们可在临床试验中进一步探索上述基因作为骨质疏松症新的治疗途径的潜力。

Abstract: BACKGROUND: With the acceleration of China's aging population, the number of osteoporosis patients has been increasing significantly. Recent advancements in genome-wide association studies and single-cell transcriptomic sequencing have empowered researchers to identify novel osteoporosis-associated genes through integrative multi-omics analyses.
OBJECTIVE: To identify potential therapeutic targets for osteoporosis using summary data-based Mendelian randomization approaches that integrate genome-wide association studies and transcriptomic data from Asian and European populations.
METHODS: By integrating cis-expression quantitative trait loci (cis-eQTL) and protein quantitative trait loci (pQTL) datasets from multiple tissues (blood and muscle-bone)(cis-expression quantitative trait loci datasets for human blood and bone-muscle tissues were obtained from the Genotype-Tissue Expression (GTEx) Project v.8, which is a large-scale international collaborative project focusing on gene expression variation across different tissues/organs and its association with genetic regulation) with osteoporosis genome-wide association study data (the 2021 European population osteoporosis genome-wide association studies data were obtained from the FinnGen database that is a large-scale genomic research project in Finland. The 2020 large-scale East Asian population genome-wide association study was obtained from Biobank Japan that is a large-scale population-based cohort study led by Japan; we employed a summary data-based Mendelian randomization approach to identify osteoporosis-associated genes. These identified genes were further analyzed using colocalization analysis, single-cell sequencing, and enrichment analysis. All data were derived from published studies or publicly accessible sources, with ethical approval and informed consent obtained for the original studies.
RESULTS AND CONCLUSION: (1) By leveraging summary data-based Mendelian randomization analysis, a total of 64 genes (following the exclusion of duplicates) significantly associated with osteoporosis were identified. Among these, the human leukocyte antigen (HLA) alleles HLA-DQA1, HLA-DQA2, HLA-DQB1, HLA-DQB2, and HLA-DRB5 were robustly validated across two independent outcome datasets. (2) Colocalization analysis further prioritized HLA-DQA2 and HLA-DQB1 as causal candidates with strong evidence of colocalization (posterior probability PPH4 > 0.8). (3) Protein quantitative trait locus (pQTL) analysis revealed that elevated plasma levels of HLA-DQA2 were associated with a reduced risk of osteoporosis. (4) Single-cell sequencing analysis indicated that, within the immune microenvironment of osteoporosis, the abundance of dendritic cells, B cells, macrophages, and neutrophils was significantly higher than that of other cell populations. (5) Enrichment analysis results showed that the identified genes were enriched in the antigen presentation pathway of major histocompatibility complex class II molecules. (6) This study preliminarily identified several previously unreported osteoporosis-associated genes through bioinformatics analyses integrating Asian and European population genome-wide association data. These genes hold potential for further exploration as novel therapeutic targets for osteoporosis in clinical trials.
