摘　　要：对有机体发育和再生的研究一直是生命科学领域探索热点之一,斑马鱼由于具有发育速度快、胚胎透明便于观察以及其尾鳍、心脏、神经系统等组织器官可以再生等众多优点,已经成为应用最为广泛的模式生物之一.在斑马鱼发育及再生过程中,细胞发生增殖、分化、形态建成等代谢活动,而对其中调控机制的研究尚未完全明确,对其深入探究的意义不言而喻,可以为很多疾病的认识治疗、组织工程的发展奠定理论基础.研究已经表明,在此过程中,有很多蛋白质参与发育及再生的调节,而蛋白质糖基化是重要的蛋白质翻译后修饰,糖基化的变化会影响细胞识别、黏附、信号传导等,从而导致炎症、肿瘤等恶性疾病的发生.近年来,糖组学的发展为发育生物学和再生医学提供了新的思路和研究成果,本文就糖基化变化在斑马鱼的发育过程中发挥的作用做一综述,并对今后它对再生过程的作用进行展望.The study on tissue development and regeneration is one of the hot spots of life science. Zebrafish has become one of the popular model organisms due to its rapid growth rate, transparent embryos which is easy to observe, and the capacity to regenerate fin, heart, nervous system, etc. During the development and regeneration process of zebrafish, cell proliferation, differentiation, morphogenesis and other metabolic activities occurs, but little is known about the regulatory mechanism among such complex dynamic processes to us. Further studies on these processes have magnificent meanings, for instance, laying a theoretical foundation for the treatment of many diseases, and also promoting the progress of tissue engineering. Previous study has shown that multifold proteins involved in the regulation of tissue development and regeneration. Protein glycosylation is an important post-translational modification, which can affect cell recognition, adhesion, and signal transduction, even lead to inflammation, cancer and other malignant diseases. In recent years, the development of glycomics provides new ideas for developmental biology and regenerative medicine. In this present review, we summarize the role of glycosylation alteration in the development process of zebrafish, and prospect for its future study on regeneration.
