Transgenic animals refer to the experimental technology of introducing foreign genes into animals. In a stable integration and inheritable animal, the animal embryos of foreign genes are successfully induced first, and the application of transgenic animal technology in obtaining transgenic animals is established. Mice are transformed into the growth hormone gene of rats, and the weight of mice is twice that of normal individuals“ After "super mouse", transgenic animals such as rabbits, sheep, pigs, fish, insects, cattle, chickens, goats, rats and other transgenic animals have been successfully transferred.

Because of the transfer of gene animal system, the natural breeding of interspecific isolation is broken, and genes flow between organisms with very far relationship between plants. Therefore, it will have a global impact on the whole life science At the first International Conference on gene mapping, it was recognized as the fourth generation technology of genetic transmission chain analysis, somatic cell genetics and gene cloning, and was listed as the tenth turning point in the history of biology. Since the publication of transgenic mice and the research of transgenic animals, remarkable achievements have been made in many fields.

According to different purposes, gene animal operation is simply divided into four categories Species types: (

1) biological research on the basis of animal improvement by using transgenic animal drugs.

转基因动物是指将外源基因导入动物的实验技术，在稳定的整合和可遗传给后代的一种动物中首先成功地诱导了外源基因的动物胚胎，建立了转基因动物技术在获得转基因动物中的应用小鼠转化为大鼠的生长激素基因，使小鼠体重为正常个体的两倍，因此被称为“超级小鼠”以后相继培养成功地转移了基因兔、羊、猪、鱼、昆虫、牛、鸡、山羊，大鼠等转基因动物因为转移了基因动物系统打破了自然繁殖的种间隔离，使基因在植物间的关系非常远的生物体间流动，因此对整个生命科学将产生全局性的影响，转基因动物技术在第一届国际基因定位会议上被公认为是遗传传递链分析、体细胞遗传和基因克隆的第四代技术，被列为生物学史上第十个转折点以来转移基因的小鼠发表、转移基因动物研究在许多领域都取得了令人瞩目的成就，根据不同的目的，将基因动物操作简单地划分为四种类型：（

1）疾病转移基因动物利用转移基因动物药物生产动物改良基础的生物学研究。

2：，Genetic engineering is a set of techniques used to change the genetic structure of cells, including the transfer of genes within species and across species boundaries to produce improved or new organisms. New DNA can be first isolated and copied from the genetic material of interest, using molecular cloning method to generate DNA sequence, or by synthesizing DNA, and then inserting this structure into the host organism, the gene can be removed or "knocked out". Using nuclease gene targeting is a different technology, which uses homologous recombination to change endogenous genes and can be used for deletion Gene, exon deletion, gene addition, or point mutation gene engineering technology has been applied in many fields, including research, agriculture, industrial biotechnology and pharmaceutical enzymes used in laundry powder.

Now transgenic cells, experimental transgenic cell lines and transgenic animals (such as mice) are used to produce drugs such as insulin and human growth hormone. Zebrafish has been used for research purposes Genetic crops have been commercialized.

基因工程是一套用来改变细胞遗传结构的技术，包括在物种内部和跨物种边界转移基因，以产生改良的或新的有机体。新的DNA可以通过首先分离和复制感兴趣的遗传物质，用分子克隆方法产生DNA序列，或者通过合成DNA，然后将这个结构体插入宿主有机体中，基因可以被移除，或者被“敲除”，使用核酸酶基因靶向是一种不同的技术，它利用同源重组来改变内源基因，并可用于删除基因、删除外显子、添加基因，或者引入点突变基因工程技术已经应用于许多领域，包括研究、农业、工业生物技术和用于洗衣粉的药物酶，现在转基因细胞、实验性转基因细胞系和转基因动物（如小鼠）生产胰岛素和人生长激素等药物斑马鱼被用于研究目的，转基因作物已经商业化。

3：基因，A study by Johns Hopkins University on Tuesday showed that an individual's genome changes during a person's lifetime due to environmental or nutritional factors, which may explain why diseases such as cancer change with age, researchers have found that so-called epigenetic markers occur in a person's DNA sequence over a lifetime The extent to which this change has changed is similar among family members. "We're starting to see epigenetics as the center of modern medicine, because epigenetic changes, unlike DNA sequences, are the same in every cell, and it could be the result of diet and other environmental exposure," said Andrew Feinberg, Professor of molecular biology and genetics at the University. "Epigenetics is likely to occur in diseases such as diabetes, autism and cancer In a study published in the Journal of the American Medical Association, he added that the team analyzed the DNA sequences of people who participated in the Reykjavik age group study.

Participants in the Reykjavik heart study, formerly known as the Icelandic Reykjavik heart study, provided DNA samples between and then scientists measured changes in methylation levels, the main epigenetic modification In about one-third of the samples, methylation levels changed after a few years. "Inappropriate methylation," said vilmundur, Professor of cardiovascular genetics at the University of Iceland "Too high a level may turn off the necessary genes, too few may turn on the genes at the wrong time or in the wrong cell," said gudnason, adding that "what we see is detectable changes over time," added Daniel farIn, associate professor of epidemiology at Johns Hopkins University's School of public health at the school of public health It does change with age, "and this change may also be genetic, which may explain why some families are more susceptible to certain diseases than others.

约翰霍普金斯大学周二的一项研究表明，在一个人的一生中，个体的基因组会受到环境或营养因素的影响而发生变化，这也许可以解释为什么癌症等疾病会随着年龄的增长而发生变化，研究人员发现，在一个人的DNA序列上，所谓的表观遗传标记会在人的一生中发生改变这种变化的程度在家庭成员中是相似的。“我们开始看到表观遗传学是现代医学的中心，因为表观遗传学的变化，不同于DNA序列在每个细胞中都是一样的，它可能是饮食和其他环境暴露的结果，”安德鲁·范伯格说，该大学分子生物学和遗传学教授“表观遗传学很可能在糖尿病、自闭症和癌症等疾病中发挥重要作用，”他在《美国医学会杂志》上发表的研究中补充道，研究小组分析了参加雷克雅未克年龄段研究的人的DNA序列，以前被称为冰岛雷克雅未克心脏研究的参与者在年和年之间提供了DNA样本，然后科学家们测量了甲基化水平的变化，这是主要的表观遗传修饰，在大约三分之一的样本中，甲基化水平在数年后发生了变化“不适当的甲基化”冰岛大学心血管遗传学教授维尔蒙杜尔古德纳森（Vilmundur Gudnason）说：“水平过高可能会关闭必要的基因，太少可能会在错误的时间或错误的细胞中开启基因，”我们看到的是随着时间的推移可检测到的变化，约翰霍普金斯大学彭博公共卫生学院流行病学副教授丹尼尔法林补充说：“这向我们证明了个人的表观遗传学确实会随着年龄的增长而变化，”这种变化也可能是遗传性的，这也许可以解释为什么有些家庭比其他家庭更容易受到某些疾病的影响。
