黏连蛋白对于基因组的三维组织是非常重要的。然而,即使完全去除粘附素对稳态基因转录和增强子活性的影响也令人惊讶地小。在这里,我们表明,粘附素是所需的核心转录反应的主要巨噬细胞的微生物信号,诱导增强子活性,支持炎症基因的表达。与炎症信号在促进造血干细胞和祖细胞(HPSC)的髓样分化中的作用一致,HSPC中的粘着蛋白突变导致炎性基因表达减少,并且对诱导分化的炎性刺激的抗性增加。这些发现揭示了一个意想不到的依赖性的诱导基因表达的凝聚素,连接凝聚素与髓系分化,并可能有助于解释的流行性凝聚素突变在人类急性髓系白血病。
Cohesin is important for 3-dimensional (3D) genome organization. Nevertheless, even the complete removal of cohesin has surprisingly little impact on steady-state gene transcription and enhancer activity. Here we show that cohesin was required for the core transcriptional response of primary macrophages to microbial signals, and for inducible enhancer activity that underpins inflammatory gene expression. Consistent with a role of inflammatory signals in promoting myeloid differentiation of hematopoietic stem and progenitor cells (HPSCs), cohesin mutations in HSPCs led to reduced inflammatory gene expression, and increased resistance to differentiation-inducing inflammatory stimuli. These findings uncover an unexpected dependence of inducible gene expression on cohesin, link cohesin with myeloid differentiation, and may help explain the prevalence of cohesin mutations in human acute myeloid leukemia.
