课程简介

课程名称:CRISPR Cas9技术 课程概述:CRISPR-Cas9是一种独特的基因组编辑技术,使遗传学家和医学研究人员能够通过移除、添加或改变DNA序列的部分来编辑基因组。目前,它是基因干扰中最简单、最灵活、最精确的方法,因此在科学界引起了广泛关注。CRISPR-Cas9作为基因组编辑工具,不仅速度快、成本低,而且比以往的DNA编辑技术更为准确,应用潜力广泛。 工作原理: 1. CRISPR-Cas9系统由两种关键分子组成:一种称为Cas9的酶,它像“分子剪刀”一样在特定位置剪切DNA;另一种是引导RNA(gRNA),其包含设计好的RNA序列,能够引导Cas9到达基因组的正确位置。 2. gRNA设计用于找到并结合到DNA上的特定序列,其RNA碱基与目标DNA序列互补。 3. Cas9跟随gRNA到达DNA序列的相应位置并进行切割。 4. 细胞识别到DNA受损并尝试修复。 5. 科学家可以利用DNA修复机制对细胞基因组中的一个或多个基因进行修改。 其他基因编辑技术: 传统的基因目标技术依赖于化学或辐射造成突变,但没有控制突变发生位置的能力。近年来,科学家开发了包括CRISPR-Cas9、TALENs和ZFNs在内的多种基因编辑技术。CRISPR-Cas9系统是效率最高、成本最低且最可靠的基因编辑系统。 应用及影响: CRISPR-Cas9在治疗包括癌症、乙型肝炎甚至高胆固醇等多种基因相关疾病方面具有巨大潜力。然而,对生殖细胞进行基因编辑的讨论引发了重要的伦理问题,因为任何对生殖细胞进行的改变将代代相传。在大多数国家中,生殖细胞的基因编辑仍然是非法的,而对体细胞进行CRISPR-Cas9编辑较为广泛接受,已经在少数特殊或危重病例中应用。 未来展望: 预计CRISPR-Cas9在医学中的日常应用还需多年的研究,目前主要集中于动物模型或人类细胞的应用,目标是最终在人体中规律性地治愈疾病。研究者还在努力消除“脱靶”效应,以确保CRISPR-Cas9只在预定基因中进行编辑。 课程适合对象:本课程适合生命科学、生物技术、生物科学等相关专业的本科及研究生,特别是希望从事临床研究领域的学生。 课程收益: - 终身有效的课程证书 - 示范视频学习 - 实践项目,将理论应用于实际情况 - 方便的随时随地访问 - 周期性作业和实时项目,增强学习信心 - 行业认可的证书,实现职业发展的良好基础 参加课程后,学员将掌握前沿的技术知识,为未来的职业发展打下坚实的基础。

What is CRISPR-Cas9?CRISPR-Cas9 is a unique technology that enables geneticists and medical researchers to edit parts of the genome by removing, adding or altering sections of the DNA sequence.It is currently the simplest, most versatile and precise method of genetic manipulation and is therefore causing a buzz in the science world.CRISPR-Cas9 is a genome editing tool that is creating a buzz in the science world. It is faster, cheaper and more accurate than previous techniques of editing DNA and has a wide range of potential applications.How does it work?1. The CRISPR-Cas9 system consists of two key molecules that introduce a change (mutation) into the DNA. These are:⦁ an enzyme called Cas9. This acts as a pair of ‘molecular scissors' that can cut the two strands of DNA at a specific location in the genome so that bits of DNA can then be added or removed.⦁ a piece of RNA called guide RNA (gRNA). This consists of a small piece of pre-designed RNA sequence located within a longer RNA scaffold. The scaffold part binds to DNA and the pre-designed sequence ‘guides' Cas9 to the right part of the genome. This makes sure that the Cas9 enzyme cuts at the right point in the genome.2. The guide RNA is designed to find and bind to a specific sequence in the DNA. The guide RNA has RNA bases that are complementary to those of the target DNA sequence in the genome. This means that, at least in theory, the guide RNA will only bind to the target sequence and no other regions of the genome.3. The Cas9 follows the guide RNA to the same location in the DNA sequence and makes a cut across both strands of the DNA.4. At this stage the cell recognizes that the DNA is damaged and tries to repair it.5. Scientists can use the DNA repair machinery to introduce changes to one or more genes in the genome of a cell of interest.What other techniques are there for altering genes?Over the years scientists have learned about genetics and gene function by studying the effects of changes in DNA.If you can create a change in a gene, either in a cell line or a whole organism, it is possible to then study the effect of that change to understand what the function of that gene is.For a long time geneticists used chemicals or radiation to cause mutations. However, they had no way of controlling where in the genome the mutation would occur.For several years scientists have been using ‘gene targeting' to introduce changes in specific places in the genome, by removing or adding either whole genes or single bases.Traditional gene targeting has been very valuable for studying genes and genetics, however it takes a long time to create a mutation and is fairly expensive.Several ‘gene editing' technologies have recently been developed to improve gene targeting methods, including CRISPR-Cas systems, transcription activator-like effector nucleases (TALENs) and zinc-finger nucleases (ZFNs).The CRISPR-Cas9 system currently stands out as the fastest, cheapest and most reliable system for ‘editing' genes.What are the applications and implications?CRISPR-Cas9 has a lot of potential as a tool for treating a range of medical conditions that have a genetic component, including cancer, hepatitis B or even high cholesterol.Many of the proposed applications involve editing the genomes of somatic (non-reproductive) cells but there has been a lot of interest in and debate about the potential to edit germline (reproductive) cells.Because any changes made in germline cells will be passed on from generation to generation it has important ethical implications.Carrying out gene editing in germline cells is currently illegal in the UK and most other countries.By contrast, the use of CRISPR-Cas9 and other gene editing technologies in somatic cells is uncontroversial. Indeed they have already been used to treat human disease on a small number of exceptional and/or life-threatening cases.What's the future of CRISPR-Cas9?It is likely to be many years before CRISPR-Cas9 is used routinely in humans.Much research is still focusing on its use in animal models or isolated human cells, with the aim to eventually use the technology to routinely treat diseases in humans.There is a lot of work focusing on eliminating ‘off-target' effects, where the CRISPR-Cas9 system cuts at a different gene to the one that was intended to be edited.Job ScopeJobs directly related to your degree include:· Academic researcher· Biomedical scientist· Clinical research associate· Clinical scientist, genomics· Clinical scientist, immunology· Genetic counselor· Plant breeder/geneticist· Research scientist (life sciences)· Research scientist (medical)Jobs where your degree would be useful include:· Biotechnologist· Data scientist· Epidemiologist· Forensic scientist· Medical science liaison· Physician associate· Scientific laboratory technician· Science writer· Secondary school teacherSalary Range Provided in Genetic Engineering field:Candidate in jobs or training period ranges from 2-2.8 Lakh per annumFor research associate, it ranges from 3.5 lakh to 5 lakh per year.Junior scientists vary from 6-9 lakh per annumWhereas for a senior scientist, it varies between 15-16 lakh per annum in private companies.Not only in India but in foreign also if you are looking for a career the average annual base salary is $159,339 to $194,895 of geneticists in the USA.
