在体侧中胚层中表达的基因,胚胎域产生的脊椎动物骨盆,骨盆带的形成显得很重要。在这些基因中,Pbx家族成员和Emx 2被发现在后肢和肩带形成中遗传相互作用。在这里,我们产生了携带Pbx 1,Pbx 2和Pbx 3以及Pbx 1和Emx 2突变等位基因组合的复合突变胚胎,以检查骨盆发育过程中潜在的遗传相互作用。事实上,Pbx基因共享重叠的功能,Pbx 1和Emx 2在骨盆形成中遗传相互作用。我们发现,在化合物Pbx 1; Pbx 2和Pbx 1; Emx 2突变体,盆腔间充质凝聚显着扰动,这些同源异型蛋白的上游控制的指示。我们确定,在我们的复合突变体中,Tbx 15,Prrx 1和Pax 1的表达,以及参与选择骨盆结构的规范和发展的其他基因被改变。最后,我们确定潜在的Pbx 1-Emx 2调节增强Tbx 15,Prrx 1和Pax 1,使用生物信息学分析。
Genes expressed in the somatopleuric mesoderm, the embryonic domain giving rise to the vertebrate pelvis, appear important for pelvic girdle formation. Among such genes, Pbx family members and Emx2 were found to genetically interact in hindlimb and pectoral girdle formation. Here, we generated compound mutant embryos carrying combinations of mutated alleles for Pbx1, Pbx2, and Pbx3, as well as Pbx1 and Emx2, to examine potential genetic interactions during pelvic development. Indeed, Pbx genes share overlapping functions and Pbx1 and Emx2 genetically interact in pelvic formation. We show that in compound Pbx1;Pbx2 and Pbx1;Emx2 mutants, pelvic mesenchymal condensation is markedly perturbed, indicative of an upstream control by these homeoproteins. We establish that expression of Tbx15, Prrx1, and Pax1, among other genes involved in the specification and development of select pelvic structures, is altered in our compound mutants. Lastly, we identify potential Pbx1-Emx2-regulated enhancers for Tbx15, Prrx1, and Pax1, using bioinformatics analyses.
