我们在这里描述的实验,以检查细胞视黄酸结合蛋白(CRABP)的作用,在诱导鸡肢芽和再生蝾螈肢的维甲酸。已经使用了一类新合成的视黄酸类似物,因为其中一些已经被特别设计为具有结合视黄酸受体的性质,但不结合CRABP。因此,我们可以测试结合CRABP是否是肢体重新指定过程中的强制性步骤。在蔗糖密度梯度测定中测试这些化合物中的四种与鸡肢芽和美西蝾螈CRABP的结合,然后测试它们诱导肢复制的效力。四种化合物中的两种不与肢体CRABP结合,但能够诱导肢体复制,这表明与CRABP的相互作用不是该过程中的强制性步骤。然而,与CRABP结合的两种化合物比不与CRABP结合的两种化合物更有效,这表明与CRABP的相互作用可以增加类视色素的效力。
We describe here experiments to examine the role of cellular retinoic-acid-binding protein (CRABP) during the induction of limb duplication in the chick limb bud and regenerating axolotl limb by retinoids. A newly synthesised class of retinoic acid analogues have been used because among them, some have been specifically designed with the property of binding to the retinoic acid receptors, but not to CRABP. We can thus test whether binding to CRABP is an obligatory step during limb respecification. The binding of four of these compounds to chick limb bud and axolotl CRABP was tested in sucrose density gradient assays and then their potencies at inducing limb duplications tested. Two of the four compounds do not bind to limb CRABP and yet are able to induce limb duplications, suggesting that an interaction with CRABP is not an obligatory step in the process. However, the two compounds which do bind to CRABP are more potent than the two which do not, suggesting that an interaction with CRABP may, nevertheless, increase the potency of a retinoid.
