多国科学家要求公开韩春雨基因编辑实验数据

2016-07-31 14:20:32   澎湃新闻网

韩春雨

河北科技大学副教授韩春雨震惊全球学术界的新基因编辑技术NgAgo-gDNA,正遭遇越来越多的质疑。从5月2日他的论文发布在《自然-生物技术》网络版之后,到现在为止,全球仍没有一家实验室对外宣布,能够完全成功重复韩春雨的实验。现在已有多国科学家要求《自然-生物技术》介入调查,并公开韩春雨实验中的所有原始数据和实验条件。

北京时间7月29日,一度支持韩春雨的澳大利亚国立大学的基因学家Gaetan Burgio,反戈一击。他在Twitter上发布长文《我的NgAgo经历》,否认了自己7月15日之前部分重复实验时得出的结论,表示并无严格意义上的证据显示韩春雨的NgAgo-gDNA技术有基因编辑的迹象,并且要求韩春雨公开所有原始数据和实验条件。

韩春雨的NgAgo-gDNA技术,挑战的是最为流行的基因编辑技术CRISPR-CAS9,论文刚一发表,就引发了轰动。基因编辑技术是指能够让人类对目标基因进行“编辑”,实现对特定DNA片段的敲除、加入等。目前CRISPR-CAS9是最为普遍的基因编辑技术,被称为“基因魔剪”。 5月2日,韩春雨课题组的论文《DNA-guided genome editing using the Natronobacterium gregoryi Argonaute》在《Nature Biotechnology》在线发表。绕开时兴的CRISPR-CAS9技术,课题组利用格氏嗜盐碱杆菌(Natronobacterium gregoryi)的Argonaute核酸内切酶,以DNA为介导进行基因组编辑,简称NgAgo-gDNA。

质疑韩春雨的Gaetan Burgio在7月29日发布的长文中介绍了重复实验的具体过程操作和结论,附带了7张实验结果图。
