Nature:张锋团队今日带来CRISPR重磅突破!靶向RNA效果比肩诺奖研究

2017-10-05 佚名 药明康德

今日,知名华人学者张锋教授与他的团队在《自然》杂志上在线刊登了一篇论文,介绍了CRISPR系统的新应用——靶向哺乳动物细胞的RNA。这一应用能特异性抑制哺乳动物细胞中的基因转录产物,效果与2006年的诺贝尔奖研究“RNA干扰”并无明显区别。这一突破性的工具对基础科研有着重要意义。

今日,知名华人学者张锋教授与他的团队在《自然》杂志上在线刊登了一篇论文,介绍了CRISPR系统的新应用——靶向哺乳动物细胞的RNA。这一应用能特异性抑制哺乳动物细胞中的基因转录产物,效果与2006年的诺贝尔奖研究“RNA干扰”并无明显区别。这一突破性的工具对基础科研有着重要意义。

说到CRISPR,许多人脑中的第一反应是CRISPR-Cas9基因编辑系统。的确,CRISPR技术改写了基因编辑的格局,但编辑DNA并不是它的全部作用。去年8月,张锋教授的课题组曾在《科学》上发文,指出一种叫做Cas13a(当时被称为C2c2)的蛋白与CRISPR进行组合,有望靶向RNA。今年4月,张锋教授团队的另一篇《科学》文章则表明,利用切割RNA的特性,CRISPR-Cas13a系统可以被改造成核酸检测工具,灵敏度可高达单分子!

研究人员们并没有就此停下脚步。Cas13a对RNA的切割能力有望让它成为基因研究中的重要工具,而我们需要确认的,是它在哺乳动物细胞内有没有应用的潜力。为了检验这个想法,研究人员们开发了一种“报告基因”系统。它带有编码两种荧光蛋白的基因,其中一条基因的RNA能被Cas13a识别和破坏,另一条则不受影响。如果Cas13a当真能在哺乳动物细胞内切割RNA,那么我们应该能预计,前一种荧光蛋白的含量会变低,而后一种荧光蛋白的含量不会出现明显变化。这正是研究人员所观察到的结果。

随后,研究人员们又探索了CRISPR-Cas13a系统对哺乳动物细胞内源基因的切割活性。他们选择了3条与癌症有关的基因KRAS、CXCR4、以及PPIB,并针对它们设计了CRISPR-Cas13a编辑系统。与外源的荧光蛋白一致,这3条内源基因的表达显着下降。换句话说,这个编辑系统对哺乳动物细胞的内源基因也同样有效。

更令人兴奋的是,研究人员还比较了RNA干扰在这三条基因上的抑制能力。RNA干扰技术曾于2006年斩获诺贝尔生理学或医学奖,在基础生物学或医学研究中有着极为广泛的应用。而本项研究表明,RNA干扰与CRISPR-Cas13a对这三条基因表达的抑制能力非常接近。换句话说,后者的抑制效果达到了诺贝尔奖研究的水平。

▲CRISPR-Cas13a系统(浅蓝)与RNA干扰(深蓝)的效果非常接近(图片来源:《自然》)

“RNA干扰与Cas13a系统的效果很相似。在有些时候,Cas13a的效果还要更好一些,”罗切斯特大学(University of Rochester)的Mitchell O’Connell教授对此赞誉有加:“在CRISPR技术诞生前,RNA干扰一直是调控基因表达的‘圣杯’。但使用Cas13a的一个好处在于,它的特异性更好。另外,它也不是哺乳动物细胞内自然形成的系统,对转录后调控网络的干扰风险也更低。”

在验证了有效性之后,研究人员们同样验证了这套系统的安全性。先前,这支团队发现Cas13a在细菌体内被激活后,会化身为非特异性的RNA酶,疯狂地切开遇到的所有RNA。这无疑是非常危险的。如果它在哺乳动物细胞内也陷入疯狂,就会破坏行使正常功能的RNA。严重时,这甚至可能导致细胞死亡。这样一来,它的应用也就无从谈起了。

▲在安全性上,CRISPR-Cas13a系统甚至要优于RNA干扰(图片来源:《自然》)

幸运的是,研究人员们的担忧并没有成为事实。Cas13a蛋白来源于一种叫做Leptotrichia wadei的微生物。或许是哺乳动物与它的演化关系过于遥远,这些Cas13a蛋白在哺乳动物细胞内非常安分守己,只切开特异的RNA,不影响其他RNA。

“这是本项工作的最大惊喜,”该论文的共同第一作者Omar Abudayyeh说道:“我们没有在哺乳动物细胞或是植物细胞中检测到任何Cas13a的额外活性。”

▲这一系统在追踪细胞内RNA的动态上还有额外的应用价值(图片来源:《自然》)

在靶向哺乳动物细胞内的RNA外,研究人员们还进一步拓展了这一技术。首先,他们表明在水稻原生质体(移除细胞壁的水稻细胞)中,CRISPR-Cas13a系统同样能靶向RNA。这表明这款工具在植物中同样有效;其次,他们还开发了一种失去酶活的Cas13a蛋白。它能结合RNA,但不会进行切割。研究人员们相信,在这些失活的Cas13a上添加荧光标记,就能追踪RNA在细胞内的移动,这也有着重要的应用价值。

自CRISPR技术诞生以来,张锋教授的实验室已经带给我们一个又一个惊喜。我们祝愿这名华人学者能走得更远,为科学带来更多CRISPR的应用。
