Cyp 26 A1是一种主要酶,通过将视黄酸(RA)代谢成无生物活性的代谢物来控制RA的稳态。先前的研究表明,小鼠Cyp 26 A1启动子具有两个典型的RA反应元件(RARE),这是RA调控该基因的基础。通过对斑马鱼cyp 26 a1启动子上游2, 533 bp(2.5k)的基因组序列分析,发现两个RARE在斑马鱼cyp 26 a1启动子中是保守的。突变实验表明,两个RARE在RA诱导cyp 26 a1表达中具有协同作用。将2.5 k(cyp 26 a1:eYFP)片段与增强型黄色荧光蛋白(eYFP)报告基因融合,获得了两个转基因斑马鱼品系[Tg(cyp 26 a1:eYFP)]。转cyp 26 a1基因斑马鱼在体内的表达模式与cyp 26 a1基因相似。与体外结果一致,报告基因活性在胚胎中是RA诱导的。两者合计,我们的研究结果表明,2.5 k片段的基础上的调节斑马鱼cyp 26 a1基因由RA。
Cyp26A1 is a major enzyme that controls retinoic acid (RA) homeostasis by metabolizing RA into bioinactive metabolites. Previous research revealed that the mouse Cyp26A1 promoter has two canonical RA response elements (RAREs) that underlie the regulation of the gene by RA. Analyzing the 2,533-base pairs (2.5 k) genomic sequence upstream of zebrafish cyp26a1 start codon, we report that the two RAREs are conserved in zebrafish cyp26a1 promoter. Mutagenesis demonstrated that the two RAREs work synergistically in RA inducibility of cyp26a1. Fusing the 2.5 k (kilobase pairs) fragment to the enhanced yellow fluorescent protein (eYFP) reporter gene, we have generated two transgenic lines of zebrafish [Tg(cyp26a1:eYFP)]. The transgenic zebrafish display expression patterns similar to that of cyp26a1 gene in vivo. Consistent with the in vitro results, the reporter activity is RA inducible in embryos. Taken together, our results demonstrate that the 2.5 k fragment underlies the regulation of the zebrafish cyp26a1 gene by RA.
