一种综合方法,对参与小鼠动脉血栓形成同时有无影响止血的431个基因的功能进行比较。

血栓形成/止血的蛋白质互作网络表明小鼠和人类具有高度相似性,同时鉴别出多个候选蛋白。

摘要:

抗血栓治疗通过预防动脉血栓形成和血栓栓塞来减少血管疾病,但同时会增加出血风险。采用转基因小鼠进行动脉血栓研究可有效鉴别新的分子靶点。由于样本量少、研究方法多异,限制了对单基因缺陷小鼠的研究进行正式的Meta分析。为克服上述问题,Constance C. F. M. J. Baaten等人开发了一种新的合成方法来定量衡量1514篇已发表的动脉血栓形成、血栓栓塞和转基因小鼠尾巴出血的研究。

使用新定义的一致性参数(CP),标明发表数据的强度,对比小鼠的431个基因,其中17个在不影响止血的情况下持续参与 血栓形成。排列分析显示,在体内外,胶原依赖性血栓形成模型之间均存在高度相关性。

积分和CP值的整合显示血栓和止血中存在蛋白相互作用网(PITH),该网可与遗传相关的人类出血和血栓疾病数据库相结合。该网络包含2946个节点,这些节点与血栓形成的修饰基因相关,主要在巨核细胞中表达。

反应组通路分析和网络特征揭示了对血栓形成/止血有潜在贡献的多重新基因。基因敲除小鼠表明新基因Apoe、Fpr2、Ifnar1和Vps13a在血栓形成中发生修饰。PITH网进一步揭示了小鼠和人类的止血/血栓形成过程有高度的相似性,同时鉴别出多个新的调控该过程的候选蛋白。
