Recently, Fang Zhouzi publicly issued a document questioning the "non-repeatable copying operation" of Han Chunyu's "Nobel Prize" experimental results of Hebei University of Science and Technology, alluding to the authenticity of Han Chunyu's scientific research results, and criticized Han Chunyu's response to the question. On May 2nd this year, Nature Biotechnology, the top publication of Nature series, was published online by Associate Professor Han Chunyu, a young teacher from the School of Biological Science and Engineering, Hebei University of Science and Technology, entitled DNA-guided genome. Editing using the Natronobacteriumgregoryi Argonaute's major original results. Han Chunyu's team invented a new gene editing technology, NgAgo-gDNA, which challenged the most fashionable technology, CRISPR-CAS9. The latter is considered to be the third generation of gene editing technology and has been a popular Nobel Prize in recent years. However, Fang Zhouzi said in the article that there are many contradictions between Han Chunyu’s remarks in public and his description in the paper. Fang Zhouzi said, “Han Chunyu emphasized in the report of Peking University and the Institute of Genetics that his current NgAgo is a preliminary version. "There is a need for superb experimental skills," and Fang Zhouzi believes that Han Chunyu describes only uncomplicated transfection experiments. It is a ready-made technique and does not require superb experimental skills. The steps provided should not be repeated. It’s the right thing to do, and there should be no “can’t repeat the experimentâ€. Fang Zhouzi said in the article, "Han Chunyu learned that someone can't repeat the results of their experiments and swear by these people" is not correct, and people doubt the authenticity of their scientific research results. The following is the full text of the question of the repetitiveness of Fang Zhouzi's "Han Chunyu's "Nobel Prize" experiment in Hebei University of Science and Technology": A new scientific discovery and technology needs to be recognized by others' repetition. It is normal for others to repeat without question. What the initiator should do is to eliminate doubts, not attacks, and embarrassment, otherwise it is even more doubtful. Not long ago, Han Chunyu of Hebei University of Science and Technology published a paper on the new method of gene editing, NgAgo, published in "Nature·Biotechnology", which was a sensation in China. Being regarded as a model of world-class scientific research by the "Intellectuals" as the final school, the other domestic media subsequently followed up the propaganda and even called the "Nobel Prize" research results. In the past few days, I have received letters from researchers from several laboratories, reflecting that the most critical Figure 4 results (cutting genome, T7E1 and sequencing) in Han Chunyu's paper are not repeated, and I am calling on this matter. image 3 Organic Balsam Pear Powder,Bitter Melon Powder,Bitter Gourd Powder,Balsam Pear Powder Hengshui Shanzhi Health Drink Co., Ltd , https://www.grasspowder-sz.com.jpg)
