Scientists and bioethicists A Chinese researcher reacted with surprise, anger, and anxiety after explaining that it helped to create the world's first genetically engineered babies.
O Jiankui between South China University of Science and Technology He said twins born earlier this month have changed their DNA to help them resist. a future infection of the virus This is an ethically and scientifically questionable target that leads to HIV.
He didn't approve what anyone else did and unpublished Experts can analyze it.
The scientific community reacted quickly and hard to the claim.
More than 100 scientists signed a petition asking for more control of genetic regulation experiments. The university where he worked stated that he would hire experts who indicated the research. "He violated academic ethics and standards seriously."
One spokesman said that he had the authority not to teach since the beginning of the year, but that he stayed in the faculty and had a laboratory at the university. Authorities in Shenzhen, the city's laboratory, also launched an investigation.
And Rice University He said he would investigate the participation of a professor of physics in the United States. Michael DeemHe said he worked with the project in China. Such genetic printing is prohibited in the United States.
"Where it's done, it's work as described in press reports It violates the standards of scientific behavior and is against the ethical standards of the scientific community and Rice University. "Said.
Genetic editing is a way of rewriting DNA., life code, trying to provide a missing gene that causes or disables problems. It has only recently been tested in adults to treat serious diseases.
Organizing eggs, sperms, or embryos is different because it makes permanent changes to future generations. The risks are unknown and leading scientists have requested a suspension in their use. Excluding laboratory testsUntil you have more information.
Among them Feng Zhang and Jennifer Doudna, powerful and simple inventors of a new tool CRISPR-cas9It was claimed that they were used in Chinese babies when they became pregnant during fertility treatments.
"I just don't think it's risky, but I'm also very concerned about the lack of transparency." Says Zhang, a scientist in the MIT Broad Institute said. Advances in medicine should be discussed
