Hong Kong –
Chinese researchers said Monday genetically modified in vitro fertilization When two twin-resistant AIDS viruses were created, an ethical criticism was created, caused by an action taken "dangerous" and "negligent".
He Jiankui, a professor at the University of Shenzhen, South China, posted two weeks ago on Youtube video, two twins, changing the DNA. Therefore AIDS viruses are resistant. Father determined that HIV was positive.
Researcher trained in the United States of Stanford and a specialized genome of Shenzhen genetics, explained The technique Crispr-Cas9, called "genetic assurances" It allows you to erase and replace unwanted parts of the genome, just like it defaults to your computer.
The children, called "Lula" and "Nana", were created as part of an embryonic in vitro fertilization in the mother's womb.
"After entering the egg field, an embryologist injects a Crispr-Cas9 protein from a future HIV infection by changing a gene protecting the girl," explains Jianku.
Genetically changing DNA can be very useful in preventing diseases, but this practice is a serious problem Genetic changes will be inherited by new generations.
MIT Technology Review recalls that "technology has an ethical responsibility".
The prediction of this medical experiment was made on the eve of the beginning of the Hong Kong World Genome Speech Conference, the Chinese researcher must present the results in detail.
However, after the critics received, the genetic conference is not guaranteed.
Self-proclaimed medical experiment It was not verified independently. The Chinese team has not published its results in the scientific journal.
– Experiment "very problematic"
After the announcement, many Chinese scientists and organizations criticized this experiment.
From February to February, he warned the university that he was receiving his salary and the transformation that we considered was "the violation of the academic and ethical criteria of its norm".
"This research was excluded from the university environment," the Southern Science and Technology University said on Monday in a statement.
A hundred Chinese scientists released a joint statement The experiment was criticized and asked to change in vitro welfare legislation.
In addition, the international critics criticized the announcement on a YouTube video
"These results predict videos on YouTube are very practical scientific problems," said Nicholas Evans, a professor of philosophy at Lowell University in Massachusetts, in the United States, working on bioethical issues.
"This eliminates the process of control over many scientific advances, such as peer evaluation," he added, because AFP questioned it.
Whether the issue is up, the issue is raised "Serious ethical problems", says Sarah Chan, from the University of Edinburgh, mentioned by Science Media Center.
"Talking about these claims seems to be most fraudulent (…) deliberately fraudulent," he added.
He did not immediately answer questions from AFP. (I)
