这是对支持脊椎动物胚胎中基因表达早期限制的假设的研究综述。我们假设脊椎动物视黄酸受体(几种脊椎动物的 RAR,但斑马鱼的 RAR)是胚胎表观遗传开关的一部分,其默认位置在受精时为“关闭”。这是由于在基因子集的调控区域中视黄酸反应元件 (RARE) 上存在 rar-辅阻遏物-组蛋白脱乙酰酶复合物。此外,在早期发育过程中,通过第一相酶的相互作用选择性和精确地分配视黄酸,以可预测的发育方式打开开关。我们提出,这是一种基本的早期胚胎转换,可以引起基因表达级联的启动,从而至少导致细胞表型的一些早期多样化。脱氢酶和细胞色素 p450 基因的子集(cyp26a1、cyp26b1 和 cyp26c1)在提供视黄酸并限制其进入方面发挥着主要作用。我们还认为,这种机制可能在未分化干细胞的基因抑制中发挥重要作用。
This is a review of research that supports a hypothesis regarding early restriction of gene expression in the vertebrate embryo. We hypothesize that vertebrate retinoic acid receptors (RARs for several vertebrates but rars for zebrafish) are part of an embryonic, epigenetic switch whose default position, at the time of fertilization is “OFF”. This is due to the assemblage of a rar-corepressor-histone deacetylase complex on retinoic acid response elements (RAREs) in regulatory regions of a subset of genes. In addition, selective and precise allocation of retinoic acid during early development through the interaction of Phase I enzymes throws the switch “ON” in a predictable, developmental manner. We are proposing that this is a basic, early embryonic switch that can cause the initiation of cascades of gene expression that are responsible for at least some early, diversification of cell phenotypes. Dehydrogenases and a subset of cytochrome p450 genes (cyp26a1, cyp26b1, and cyp26c1) play the major role in providing the retinoic acid and limiting its access. We also suggest that this mechanism may be playing a significant role in the repression of genes in undifferentiated stem cells.
