[摘要] 斑马鱼因具有体外受精、胚胎透明及繁殖能力强等小模式生物独特优势,近十年已经被广泛作为人类相关性疾病研究模型。目前针对斑马鱼的基因操作技术已相当成熟,靶向性地诱导或敲除体内某些基因,改变其表达水平,可以很容易地在斑马鱼上复制人类的一些肿瘤性疾病状态,因此适合建立斑马鱼各种类型肿瘤模型,并进行相关机制研究。本文就斑马鱼作为肿瘤模型的优势及斑马鱼各种类型肿瘤模型的研究做一综述,分析斑马鱼作为模式动物在抗肿瘤药物的研究中的应用价值。

[Abstract] Zebrafish have been successfully widely used as a research models for human-related diseases in the past decade due to their unique advantages in small-scale Organisms such as in vitro fertilization, embryo transparency and strong reproductive ability. At present, the gene manipulation technology for zebrafish has been quite mature, Targeting to induce or knock out certain genes in the body and change its expression level, it is easy to replicate some human tumor diseases on zebrafish, so various types of zebrafish tumor models can be established, and are suitable for conducfing reserch on related mechanisms. This article reviews the advantages of zebrafish as a tumor model and the research of various types of zebrafish tumor models, and the application value of zebrafish as a model animal in the study of anti-tumor drugs was analyzed.

近年來,我国患肿瘤的发病率和死亡率迅速上升,为了进一步了解肿瘤的发病机制,明确其致病机制对人类健康十分重要。动物模型是研究人类疾病的重要工具。斑马鱼基因组和人类基因组有高度同源性,作为一种新型整体实验动物模型具有极大的优势。由于斑马鱼具有透明及繁殖能力强的特点,更易于用于开展肿瘤发生发展机制研究及肿瘤药物筛选,以及研究肿瘤生物学特性等工作。本文主要就斑马鱼作为肿瘤模型的优势及斑马鱼各种类型肿瘤模型的研究给予综述。
1 斑马鱼作为肿瘤模型的优势
斑马鱼是一种产于南亚的热带鱼,近年来被广泛应用于肿瘤的研究及药物的研发。作为一种新型的整体实验动物模型,与小鼠相比,斑马鱼具有以下优点:①斑马鱼胚胎发育在母体外进行,在受精24 h内许多器官已经发育,用显微镜可以实时活体观察。……
