本研究的目的是检验我们之前的假设,即原始放线鱼鳞片表面发现的高度矿化层 ganoine 可能与覆盖脊椎动物牙冠的牙釉质同源。方法:用三种针对哺乳动物牙釉蛋白的抗体,对原始多鳍鱼 Calamoichthys calabaricus 的再生鳞片进行了免疫细胞化学技术。结果:本研究提供了第一个证据,证明甘诺因含有与哺乳动物牙釉蛋白发生交叉反应的分子。结论:这一结果与我们之前的发现一致,即甘氨酸和牙釉质可以被认为是同源组织。此外,在ganoine中存在一种原始放线鱼类的牙釉蛋白样蛋白,该蛋白与哺乳动物牙釉质的牙釉蛋白具有相同的表位,这表明编码这些蛋白的基因出现的时间早于之前的推测,并支持了牙釉蛋白在脊椎动物进化过程中表现出高度保守结构的假设。阿纳特。推荐。 249:86–95, 1997。© 1997 Wiley-Liss, Inc.
The account of the present study is to test our previous hypothesis that ganoine, a highly mineralized layer found at the scale surface of primitive actinopterygian fish, could be homologous with the enamel covering the crown of vertebrate teeth. Methods: Immunocytochemical techniques have been carried out on regenerating scales of a primitive polypterid, Calamoichthys calabaricus,with three antibodies to mammalian amelogenins. Results: The present study provides the first evidence that ganoine contains molecules which cross‐react with mammalian amelogenin proteins. Conclusions: This result is consistent with our previous findings that ganoine and enamel can be considered as homologous tissues. Moreover, the presence in ganoine of a primitive actinopterygian of amelogenin‐like proteins, which share epitopes with amelogenins of mammalian enamel, indicates that the gene(s) coding for these proteins appeared earlier than previously suggested and supports the hypothesis that amelogenins show a highly conserved structure through vertebrate evolution.
