中文摘要:
      用15%聚丙烯酰胺凝胶电泳分析比较了鲢鱼早期发育的四个重要阶段:原肠后期、心跳期、出膜期幼鱼和眼色素出现期幼鱼的细胞核组蛋白。这四个时期细胞的核心组蛋白(H4、H2a、H2b、Ha)没有明显的变化。但是,随着细胞分化的进程,H1 表现出明显的差异。在这四个时期中也可看到红细胞特有的组蛋白 H5。文章讨论了组蛋白 H1 在鲢鱼早期发育阶段对细胞分化的可能调节作用。
英文摘要:
      By using 15% polyaorylamide disc gel electrophoresis, nuclear histones of four early developmental stages in silver carp were studied, these four stages are: the late gastrulation; the heart beating; immediately after hatching and the larvae of eye pigmented stages.In these four stages, the core histones(H4、H2a、H2b、Ha) do not show any change.Nevertheless, there are many remarkable changes in number and quantities of H1 histone in accompany with the degree of cell differentiation, and the historic H5 which has been discovered in the erythrocytes of some other fishes also appeares in these stages of silver carp likewise.The possible regulating notions of historic H1 in cell differentiation of the early developmental stages in silver carp were discussed in this paper.
