转录因子Pax 3和Zic 1是神经板边缘决定细胞命运的两个重要调节因子,它们协同作用以促进神经嵴(NC)的形成。为了了解这些因素在NC发展中的作用,我们进行了微阵列分析,以确定在非洲爪蟾胚胎Pax 3和Zic 1的下游目标。在所鉴定的基因中有转录因子激活蛋白2(Tfap 2)家族的成员Tfap 2 ε(Tfap 2 e)。Tfap 2 e首先在NC祖细胞和Rohon-Beard感觉神经元的早期神经胚阶段表达,并在迁移的颅NC细胞的子集中持续存在,因为它们填充咽弓。这与在早期NC谱系中未检测到Tfap 2 e的其他物种形成对比。Tfap 2 e吗啉介导的敲低导致NC祖细胞的损失和神经板的扩张。Tfap 2 e也足以激活动物帽外植体中的NC特异性基因,并且在整个胚胎中的功能获得实验表明Tfap 2 e可以促进NC形成。我们建议,Tfap 2 e是一个新的球员在基因调控网络控制NC规格爪蟾下游的Pax 3和Zic 1。
Transcription factors Pax3 and Zic1 are two important regulators of cell fate decision at the neural plate border, where they act synergistically to promote neural crest (NC) formation. To understand the role of these factors in NC development we performed a microarray analysis to identify downstream targets of Pax3 and Zic1 in Xenopus embryos. Among the genes identified was a member of transcription factor activator protein 2 (Tfap2) family, Tfap2 epsilon (Tfap2e). Tfap2e is first expressed at early neurula stage in NC progenitors and Rohon-Beard sensory neurons, and persists in a subset of migrating cranial NC cells as they populate the pharyngeal arches. This is in contrast to other species in which Tfap2e is not detected in the early NC lineage. Tfap2e morpholino-mediated knockdown results in a loss of NC progenitors and an expansion of the neural plate. Tfap2e is also sufficient to activate NC-specific genes in animal cap explants, and gain-of-function experiments in the whole embryo indicate that Tfap2e can promote NC formation. We propose that Tfap2e is a novel player in the gene regulatory network controlling NC specification in Xenopus downstream of Pax3 and Zic1.
