Chinese researcher said Monday that had in vitro fertilization with & # 39; genetically modified twins gave rise to resistant to the AIDS virus, notice proposed ethical criticism for an act considered "dangerous" and "irresponsible".

He Jiankui, a professor at the University & # 39; Shenzhen in southern China, announced a video on YouTube 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 specialized laboratory in the genome in & # 39; Shenzja, explained that he used the Crispr technique Cas9, called "genetic scissors", which allows to remove and replace parts unwanted genome, how to fix the computer fault.

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; serves to prevent the disease, but this practice is problematic because the genetic modifications 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 was 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 in South & # 39; a statement on Monday.

Hundred Chinese scientists also published a joint statement criticizing the experiment and ask for changes in the law on 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 you announce or not, the issue raised "serious ethical concerns", says Sarah Chan, a & # 39; University & # 39; Edinburgh, cited by the Science Media Center.

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

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