Hong Kong –

Chinese researcher said Monday that he had to In vitro fertilization with & # 39; genetically modified which gave rise to twins who were resistant to the AIDS virus, which caused notice ethical criticisms & # 39; act considered "Dangerous" and "irresponsible".

It Jiankui, a professor at the University & # 39; Shenzhen in southern China, asked on YouTube video announcing the birth a few weeks ago & # 39; twin whose DNA has been modified. to be resistant to the AIDS virus. He stated that the father is HIV positive.

The researcher, trained at Stanford in the United States and conduct laboratory & # 39; & # 39 specialist in genome; Shenzja, had explained that The Crispr-Cas9 technique, called "genetic scissors", which allows to remove and replace the unwanted parts of the genome, because the damage is corrected in the computer.

The baby, called "Lula" and "Nana", born from in vitro fertilization & # 39; modified embryo before being implanted in the mother's womb.

"After injecting sperm & # 39; men in eggs, embrijott Crispr injected the protein-Cas9 charged with modifying a gene to protect girls from future HIV infection", explained Jiankui.

The modification of & # 39; & # 39 genetically DNA can; be helpful in avoiding illness, but this practice is problematic because genetic modifications be inherited by the new generations.

The of MIT Technology Review noted that "technology has ethical responsibility".

The announcement & # 39; this medical experiment took place on the eve of the start of & # 39; conference & # 39; & # 39 worldwide experts; genomes f & # 39; Hong Kong during the Chinese researcher will present its findings in detail.

However, after receiving criticism, his speech at & # 39; this congress of genetics is not guaranteed.

This self-proclaimed medical experiment Has not been verified by & # 39; independently. The Chinese team did not publish his results in & # 39; scientific journal.

– Experiment "very problematic"

After the announcement, many Chinese scientists and institutions have criticized this experiment.

The university works which reports that he stopped receiving his salary from February and found that fertilization with modified genes represented a "violation of the ethical criteria of the academy and its norms".

"This research was carried out by the university framework," said University of Science and Technology South in a statement on Monday.

Hundred Chinese scientists also published a joint statement criticizing the experiment and requested that the legislation be modified in vitro fertilization.

In addition, international researchers have criticized the announcement was made by & # 39; Video on YouTube

"The announcement of & # 39; these results in & # 39; a video on YouTube is very problematic scientific practice", thought Nicholas Evans, professor of philosophy at the University & # 39; Lowell Massachusetts, in the United States, working on issues bijoetiċi.

"This removes processes & # 39; control, which support many scientific advances, such as peer assessment," he added, questioned by AFP.

If announced or not, the subject raises "Serious ethical concerns", says Sarah Chan, a & # 39; University & # 39; Edinburgh, cited by Media Science Center.

"The such requests, apparently to seek maximum deliberately & # 39; controversies (…), are irresponsible", he added.

He Jiankui not immediately respond to questions & # 39; AFP. (I)
