作为最大的细胞核糖核蛋白复合体的主要组成部分,进化高度保守的主要拱顶蛋白(MVP)在多个器官的再生中起着至关重要的作用。在目前的研究中,我们使用最近培育的MVP基因敲除斑马鱼品系来表征MVP在器官再生过程中的功能。我们发现,在MVP基因敲除的斑马鱼中,心脏、脊髓和鳍的再生能力被保存下来。进一步的实验证明,在受损的MVP基因敲除斑马鱼中,细胞死亡增加,而转录组的格局基本没有变化。这些数据表明,MVP在斑马鱼损伤反应的早期阶段作为一种抗凋亡因子发挥作用,而在斑马鱼的再生程序中起着微不足道的作用。主要拱顶蛋白,再生,斑马鱼,基因敲除,抗凋亡作用,生物科学,细胞生物学,细胞死亡,发育遗传学,再生医学。
As the main constituent of the largest cellular ribonucleoprotein complex, the evolutionary highly conserved major vault protein (MVP) has been proposed play vital roles in the regeneration of multiple organs. In current study, we use a mvp knockout zebrafish line recently generated to characterize the function of MVP during organ regeneration. We found the regenerative capacity of heart, spinal cord and fin is preserved in mvp knockout zebrafish. Further experiments demonstrated in injured mvp knockout zebrafish, the cell death is enhanced while the transcriptome landscape is largely unchanged. These data showed MVP acts as an anti-apoptotic factor at early phase of injury response while plays a dispensable role in the regenerative programs in zebrafish.
