利用果蝇配对规则基因的同源盒甚至被跳过作为杂交探针,分离出非洲爪蟾同源盒基因Xhox3。Xhox3首先在囊胚中过渡期转录;RNA水平在神经发育早期达到峰值,随后下降。在Xhox3表达的早期,即原肠胚期和神经胚期,转录本沿中胚层的前后轴呈分级分布,并主要集中在后极。在表达后期,即尾芽期和蝌蚪期,转录本集中在胚胎的两端:前神经系统和后尾芽。实验扰动胚胎中Xhox3的表达分析表明,中胚层不同的A-P命运与不同水平的Xhox3表达相关。基于这些结果和其他同源盒基因的结果,我们提出了同源盒基因在a - p胚胎轴模式中的作用。
A Xenopus laevis homeobox gene, Xhox3, has been isolated using the homeobox of the Drosophila pair-rule gene even skipped as a hybridization probe. Xhox3 is first transcribed at the midblastula transition; RNA levels peak at the early neurula stage and decrease thereafter. During the early period of Xhox3 expression, the gastrula and neurula stages, transcripts are found in a graded fashion along the anteroposterior (A-P) axis in the mesoderm and are most concentrated at the posterior pole. In the late period of expression, the tailbud and tadpole stage, transcripts are concentrated at the two ends of the embryo: in the anterior nervous system and posterior tail bud. Analysis of Xhox3 expression in experimentally perturbed embryos shows that different A-P fates in the mesoderm are correlated with different levels of Xhox3 expression. Based on these results and those with other frog homeobox genes, we propose a role for homeobox genes in the patterning of the A-P embryonic axis.
