12 scholars said no repeat Han Yu spring experimental third party survey – Sohu news-2828创业网

12 scholars said no "repeat" Han Yu spring experimental third party survey – Sohu news the evening of October 10th, 12 scholars stand out, they decided to open the real name of "Repetition" Han spring experimental methods: "negative" and "work" and so on. The popular expression of this conclusion is that they failed to "repeat" Han Chunyu’s experiment, the experimental method is "suspect". This is not the first time someone questioned Han Chunyu’s experimental approach, but willing to stand up and accept public media interviews, but very rare. At the beginning of May this year, the Hebei University Of Science and Technology associate professor Han Chunyu in Nature Biotechnology ("nature? Biotechnology") issued a paper claimed to have discovered a new gene editing method "NgAgo", after being questioned the so-called "new method, not repeat the experiment". Today morning, science and Technology Daily published on the front page report "Han Chunyu" failed to repeat the experiment a "science and Technology Daily reporter asked", which refers to "Han Chunyu (say): they (referring to repeat the failure of experimental scientists, reporters note) if the real name, we let the real name out to repeat the experiment successful people." College of life sciences, Peking University researcher Wei Wensheng is one of the 12 scholars, he said to Han Chunyu today said, many scholars, including his thought, "can’t wait, must be sound, let the international scientific community to see us in the field (i.e., gene editing) Chinese scientists attitude." Wei Wensheng told reporters China Youth Daily? Youth online, in the past few months, his laboratory four or five students, according to the method mentioned in the paper Han Chunyu, do many times, try different, but the results were not found in genomic sequence changes, namely "experimental methods not repeated verification". Wang Haoyi, a researcher at the Institute of zoology, Chinese Academy of Sciences, got similar results. For Han Chun article in the higher efficiency of the three gDNA, two of his students, respectively, for endogenous gene editing, but can not detect the target gene mutation. He also said, "we also tried two times to transfect gDNA, prolong the incubation time, but no positive results." He said that a number of teachers in accordance with the description of the Korean paper, using the same cell line, the same gDNA, for the same target gene editing, but still did not get positive results. In fact, the other 10 scholars today are willing to stand out the real name publicly, the Medical Research Institute of life science Zhejiang University professor Wang Liming, Peking University professor Xiong Jingwei, Chinese Academy of Sciences Institute of molecular animal researcher Li Wei, Institute of Biophysics researcher Wang Xiaoqun, College of life sciences, Peking University researcher Sun Yujie, Shanghai Institute of life science and biological cells researcher Li Jinsong, College of life sciences, Shanghai Jiao Tong University professor Wu Qiang, Wenzhou Medical University professor Gu Feng, East China Normal University researcher Li Dali, Chinese Academy of Sciences Shanghai Life Science Institute researcher at the Institute of neuroscience Yang Hui, also to the China Youth Daily reporter said, the laboratory where they did not "repeat" Han Chunyu experiment.
