The posterior HOXD enhancer is an EWSR1::FLI1-dependent regulator of HOXD13 expression in Ewing sarcoma. HOXD13 expression promotes a mesenchymal cell state. Through antagonistic transcriptional programs, EWSR1::FLI1 and HOXD13 serve as master regulators of Ewing cell plasticity. Targeting Ewing cells as they exist in/transition between mesenchymal states is a priority. See related article by Apfelbaum et al., p. 4466.
后部 HOXD 增强子是 Ewing 肉瘤中 EWSR1::FLI1 依赖性 HOXD13 表达的调节剂。HOXD13 的表达促进了间充质细胞状态。通过拮抗转录程序,EWSR1::FLI1 和 HOXD13 作为 Ewing 细胞可塑性的主要调节剂。以 Ewing 细胞存在于/过渡到间充质状态的状态为靶点是当务之急。见 Apfelbaum 等人的相关文章,第 4466 页。
