摘要:



文题释义:
棕榈酰化:是一种脂质修饰过程,在骨关节炎研究中,棕榈酰化被认为可能通过调控关键蛋白质的活性或分布,参与炎症反应与组织修复过程,从而对骨关节炎的发生与发展产生重要影响。
孟德尔随机化:是一种利用遗传学原理探究暴露因素与疾病之间因果关系的分析方法,该方法将遗传变异作为工具变量,避免传统观察性研究中常见的混杂因素和逆向因果关系的干扰,为因果推断提供了更为精确的证据。

背景:研究表明,棕榈酰化调控骨关节炎具有一定的优势,故有必要选用全基因组数据,从基因遗传的角度探究骨关节炎棕榈酰化调控的新型关键药物组织构建靶点。
目的:采用孟德尔随机化方法探究棕榈酰化调控骨关节炎的新型关键药物靶点,为骨关节防治的组织构建提供参考。
方法:将31种棕榈酰化基因(源自3篇以往研究)与15 695种可成药基因(源自eQTLGen Consortium数据库,该数据库由荷兰格罗宁根大学发布,该数据旨在从血浆蛋白组基因层面更好地认识疾病,包含多种可成药基因靶点)进行匹配,得到22种棕榈酰化潜在药物靶点,并采用药靶孟德尔随机化、敏感性分析以及共定位分析,确定棕榈酰化调控骨关节炎(源自GWAS Catalog数据库,该数据库由美国国家人类基因组研究所创立,汇总了从已发表的全基因组关联研究中提取的数据,包含多种疾病的遗传关联数据)的新型药物靶点,进行GeneMANIA及STRING互作网络分析,探究棕榈酰化调控骨关节炎新型药物靶点的潜在互作蛋白。经骨关节炎验证基因(同样源自GWAS Catalog数据库)进一步验证后,确定棕榈酰化调控骨关节炎新型药物靶点的互作蛋白。
结果与结论:①31种棕榈酰化基因经配对后得到22个棕榈酰化潜在药物靶点,采用孟德尔随机化、敏感性分析以及共定位分析后,得到含锌指DHHC型结构域2这一棕榈酰化调控骨关节炎的新型药物靶点。经GeneMANIA及STRING互作网络分析后得到7个潜在互作蛋白,经骨关节炎验证基因验证后提示含锌指DHHC型结构域3与含锌指DHHC型结构域2间具有较强的互作关系。结果表明:含锌指DHHC型结构域2是棕榈酰化调控骨关节炎发生发展的新型关键药物靶点,含锌指DHHC型结构域3作为含锌指DHHC型结构域2的互作蛋白,可发挥协同作用,有助于未来通过棕榈化调控构建高效、安全的骨关节患者药物防治链。②采用国际数据库和欧洲群体进行分析对于中国的生物医学研究与临床医学研究具有重要的借鉴意义,能从基因遗传角度为中国人群的骨关节炎研究提供参考线索,同时也可借鉴此思路筛选中国人群的药物基因靶点,靶向调控棕榈酰化,推动骨关节炎防治的个性化和精准化用药。

Abstract: BACKGROUND: Studies have suggested that palmitoylation-mediated regulation offers distinct advantages in osteoarthritis. Therefore, it is essential to utilize whole-genome data to explore novel key drug-targetable tissue-constructing hubs of palmitoylation regulation in osteoarthritis from a genetic perspective.
OBJECTIVE: To explore novel key drug targets involved in palmitoylation-mediated regulation of osteoarthritis pathogenesis through Mendelian randomization analysis, thereby providing valuable insights for developing targeted therapeutic strategies against osteoarthritis.
METHODS: We identified 31 palmitylation-related genes from three independent studies and cross-referenced them with 15 695 druggable genes from the eQTLGen Consortium database (which is published by the University of Groningen in the Netherlands, and aims to enhance the understanding of diseases at the plasma proteome genetic level and includes multiple druggable gene targets), yielding 22 potential drug targets for palmitylation regulation. Using Mendelian randomization, sensitivity analysis, and colocalization analysis, we further investigated these targets to identify novel candidates for palmitylation-mediated osteoarthritis [osteoarthritis genome-wide association study (GWAS) data sourced from the GWAS Catalog, National Human Genome Research Institute, USA, which integrates data extracted from published GWAS studies and contains genetic association data for various diseases]. GeneMANIA and STRING interaction network analyses were performed to explore the potential interacting proteins of these novel drug targets. After further validation with osteoarthritis-associated genes (also sourced from the GWAS Catalog database), the interacting proteins of the palmitoylation-mediated novel drug targets for osteoarthritis were confirmed.
RESULTS AND CONCLUSION: (1) Thirty-one palmitylation-related genes were paired to obtain 22 potential drug targets, zinc finger DHHC-type containing 2 was identified as a novel therapeutic target for palmitylation-mediated osteoarthritis, following Mendelian randomization, sensitivity analysis, and colocalization analysis. GeneMANIA and STRING network analyses further revealed seven potential interacting proteins, among which zinc finger DHHC-type containing 3 exhibited a particularly strong functional association with zinc finger DHHC-type containing 2. These findings suggest that zinc finger DHHC-type containing 2 serves as a key druggable target in palmitylation-mediated osteoarthritis pathogenesis, while zinc finger DHHC-type containing 3 may act as a synergistic interactor. This provides a foundation for developing effective and safe therapeutic strategies for patients with osteoarthritis by targeting this regulatory axis. (2) The use of international databases and European population data provides valuable insights to enhance biomedical and clinical researches in China. These comprehensive resources, characterized by large sample sizes and robust datasets, not only enable the identification of novel regulatory targets but also serve as crucial reference benchmarks for osteoarthritis studies in the Chinese population. Such cross-population analytical approaches empower Chinese researchers to systematically pinpoint druggable genetic targets and develop personalized, precision therapeutic strategies for osteoarthritis through the modulation of palmitylation pathways.
