The Nobel Prize-winning experiment of the Chinese scholar Han Chunyu’s team has recently caused some people to question. The skeptics believe that this new gene editing technology can not be repeated, for the purpose of besieging Han Chunyu as a "counterfeit", but there are many people who are crowded with Han Chunyu. In response to these heated discussions, the reporter launched an investigation.
On May 2, 2016, Han Chunyu, an associate professor at Hebei University of Science and Technology, published a research report in the journal of the world's top journal Nature Biotechnology. His team invented a new gene editing technology, NgAgo-gDNA, which challenged the most fashionable technology, CRISPR-Cas9. CRISPR-Cas9 is considered to be the third generation of gene editing technology and has been a popular Nobel Prize in recent years.
Since then, Han Chunyu has been widely concerned by the media, and has been called "net red" by netizens, and has been praised by the majority of netizens as a model for "cold" scholars.
Shortly thereafter, it was suggested that Han Chunyu’s experiment could not be repeated. Some people said that it could be repeated, and the debate was endless and difficult to conclude. On July 29th, the Australian National University researcher Gaitan Bourges, who had previously announced the results of the Han Chunyu experiment, said that although he and his colleagues had tried many times in the past month, they finally found that NgAgo could not carry out the gene. edit. He called on Nature and Biotechnology magazine to ask Han Chunyu to disclose the original data. In addition, many scientists, such as the United States and Spain, also said that it is impossible to repeat the genome editing results of the Han Chunyu NgAgo system.
On August 2, a media report reported that a spokesperson for the journal Nature, Biotechnology, a British journal published in the paper, said that some researchers were aware of the concerns and would investigate the matter in accordance with established procedures. The spokesperson also said: "As one of the conditions for publishing a paper in the journal of 'Natural Science Research', the author must provide the materials, data, code and related experimental procedures to the reader in a timely manner, and cannot be unduly restricted."
Han Chunyu said in an interview with the media recently that his paper is true. "Our laboratory has been repeated many times."
