  • 在FA患者中识别与核细胞平衡相关的基因.
  • 在FA中使用单细胞RNA测序 (scRNA-seq) 分析细胞-细胞通信.

主要方法:

  • 来自FA患者 (FANCA,FANCC变体) 和健康捐赠者的血造干细胞的转录组分析.
  • 单细胞RNA测序 (scRNA-seq) 数据分析.
  • 轨迹分析以阐明细胞分化的途径.
  • 开发一种急性髓性白血病 (AML) 预测的预后模型.

主要成果:

  • 在FA患者和健康个体之间观察到细胞-细胞通信的显著差异.
  • 在FA患者中发现了涉及TNFSF13B,MIF,IL16和COL4A2的高度相互作用.
  • 对AML的预后模型显示出高预测准确性 (AUC>0.83在3年和5年).

结论:

  • 这项研究强调了Fanconi贫血中细胞通信网络的改变.
  • 开发的预后模型提供了一个有价值的工具,用于使用转录组衍生基因预测AML的结果.
