Nat. Biotechnol. 34, 768–773 (2016); published online 2 May 2016; addendum published after print 28 November 2016; retracted 2 August 2017; doi:10.1038/nbt.3547
We are retracting our study because of the continued inability of the research community to replicate the key results in Figure 4, using the protocols provided in our paper. In this figure we report that the Natronobacterium gregoryi Argonaute can efficiently create double-strand breaks and edit the genome of human cells using 5ʹ phosphorylated single-stranded DNA as a guide. Despite the efforts of many laboratories (Protein Cell 7, 913–915, 2016; Nat. Biotechnol. 35, 17–18, 2017; Cell Res. 26, 1349–1352, 2016; PLOS One 12, e0177444, 2017), an independent replication of these results has not been reported. We are therefore retracting our initial report at this time to maintain the integrity of the scientific record. We nevertheless continue to investigate the reasons for this lack of reproducibility with the aim of providing an optimized protocol.

由于科研界一直无法根据我们论文提供的实验方案重复出论文图4所示的关键结果,我们决定撤回这项研究。在该图中,我们报告说,利用5′磷酸化单链DNA作为引导,NgAgo(Natronobacterium gregoryi Argonaute)能够有效引起双链断裂,并对人体细胞基因组进行编辑。虽然许多实验室都进行了努力(Protein Cell 7, 913-915, 2016; Nat. Biotechnol.35, 17-18, 2017; Cell Res.26, 1349-1352, 2016; PLOS One 12, e0177444, 2017) ,但是没有独立重复出这些结果的报告。因此,我们现在撤回我们的最初报告,以维护科学记录的完整性。不过,我们会继续调查该研究缺乏可重复性的原因,以提供一个优化的实验方案。
