遗传疾病是指由于遗传物质的改变导致的疾病,能够通过生育遗传给后代,是困扰人类健康的一类重要疾病。彻底根治遗传疾病的方法是通过基因治疗的手段在生殖细胞中修复改变的遗传物质,并将正确的遗传物质传递给下一代,产生健康的个体,从而在人群中彻底清除遗传缺陷。然而,目前存在的基因修饰手段不能有效地在生殖细胞中进行遗传编辑。 12月5日,国际学术期刊《细胞研究》(Cell Research)在线发表了中国

遗传疾病是指由于遗传物质的改变导致的疾病,能够通过生育遗传给后代,是困扰人类健康的一类重要疾病。彻底根治遗传疾病的方法是通过基因治疗的手段在生殖细胞中修复改变的遗传物质,并将正确的遗传物质传递给下一代,产生健康的个体,从而在人群中彻底清除遗传缺陷。然而,目前存在的基因修饰手段不能有效地在生殖细胞中进行遗传编辑。

12月5日,国际学术期刊《细胞研究》(Cell Research)在线发表了中国科学院上海生命科学研究院生物化学与细胞生物学研究所李劲松研究组和吴立刚研究组以及北京大学汤富酬研究组的一项合作研究,研究人员利用CRISPR-Cas9技术在小鼠的精原干细胞中修复了遗传缺陷,产生了完全健康的后代。这项研究为人类基因治疗提供了一个新的思路。

CRISPR-Cas9技术是利用一段与靶序列相同的单导向RNA来引导Cas9核酸酶对特异靶向DNA进行识别和切割,造成DNA的双链或单链断裂,然后,细胞会利用自身具备的两种DNA修复机制对断裂的DNA进行修复,即非同源性末端接合(Non-homologous end joining, NHEJ)或同源介导的修复(Homology-directed repair, HDR)。这一技术简单高效,自问世以来已被广泛地应用于各种模式生物建立遗传修饰的模型。

2013年,李劲松研究组通过将CRISPR-Cas9系统直接注入携带遗传缺陷的受精卵胚胎中治愈了小鼠的白内障遗传疾病(Wu et al; Cell Stem Cell, 2013, 13:659),首次证明CRISPR-Cas9技术能够高效地用于遗传疾病的治疗。而这种通过直接胚胎注射的方法存在两个问题:一是新生小鼠被治愈的机率较低,约为30%;二是存有少量实验脱靶现象。

在此基础上,为更好地解决这些问题,研究人员从白内障小鼠的睾丸中获取了携带纯和遗传突变的精原干细胞。精原干细胞是一类可以在体外长期培养、能够维持稳定的表观遗传特性、并能在受体小鼠中产生功能配子的生殖干细胞。研究人员将CRISPR-Cas9转入精原干细胞系中,通过单细胞扩增的方式建立了一系列来自单个精原干细胞的细胞系。随后,研究人员对这些细胞系进行了深入分析,选择满足以下三个条件的细胞系进行移植实验:1)通过基因型分析确定两个突变位点均已修复;2)通过预测脱靶位点测序或者全基因组测序确定不存在脱靶问题;3)通过特定印记基因甲基化鉴定或者全基因组甲基化测序,确定修复的精原干细胞维持正常的表观遗传特性。最后,将这些“优质”细胞移植到去除了生殖细胞的受体小鼠睾丸内后,研究人员获得了100%完全健康的小鼠。

CRISPR-Cas9技术介导的生殖细胞遗传修复为人类基因治疗提供了一条新的思路。今后的研究需要验证这一技术路线在人类的生殖细胞中实施的可行性。

吴宇轩、周海、范小英、张英和张满为本文的共同第一作者,参与该研究的合作单位和人员包括上海市计划生育研究所施惠娟研究员、西华大学伍春莲教授等,工作得到了国家科技部、国家基金委、中国科学院(干细胞先导专项)以及上海市科委经费的支持。

Nat Protoc:利用CRISPR/Cas系统构建出了多个基因突变的大鼠品系

来自华东师范大学的研究人员通过将RNA直接注入到单细胞胚胎中,利用CRISPR/Cas系统构建出了多个基因突变的大鼠品系。这一重要的研究成果发布在9月25日的《Nature Protocols》杂志上。华东师范大学生科院生命医学研究所刘明耀(Mingyao Liu)教授和李大力(Dali Li)副教授是这篇论文的共同通讯作者。前者主要从事G蛋白偶联受体(GPCR)在个体发育和重大疾病发生发展过

Nature:科学家利用CRISPR构建癌症模型

=肿瘤细胞基因组测序已揭示出成千上万的癌症相关突变。培育携带遗传缺陷的小鼠品系是揭示这些突变作用的一种方法,但培育这样的小鼠是一个费钱耗时的过程。[pdf free]现在,麻省理工学院的研究人员找到了一种替代方法:他们证实利用称作为CRISPR的一种基因编辑系统可将致癌突变导入到成年小鼠的肝脏中,这使得科学家们能够更快速地筛查这些突变。在发表于8月6日《自然》(Nature)杂志上的论文中,研究人

麻省理工学院生物工程和电子工程及计算机科学系副教授Timothy Lu带领的科研团队分别于9月21日和8月11日在Nature Biotechnology和Proceedings of the National Academy of Sciences上发表了消除抗药型细菌的新方法。 近年来,新的细菌株系不

基因编辑工具CRISPR/Cas9:创造新生命

细菌也有敌人,其最大的敌人之一是噬菌体,因为后者可以进攻和吞食细菌。面对攻击,细菌最有效的还击是,“祭”出一种武器 CRISPR,以保护自身。CRISPR有些拗口,称为规律成簇间隔短回文重复,实际上就是一种基因编辑工具(又称为 CRISPR-Cas9 系统),是细菌用以保护自身对抗病毒的一个系统,也就是一种对付攻击者的基因武器。 初识基因编辑工具 1
