A Chinese scientist has changed human nuclear acid … and experts condemn the process of modification Health

A group of experts criticized a team of Chinese scientists who claimed to have succeeded
To change the DNA of twins to immunize against HIV
AIDS

Experts from the University of Science and Technology of Southern China,
The world Sunday night, November 25, when they claimed to have managed to give birth
After the introduction of genetic modification of embryos.

Said Dr. Gian Jianwei, a senior
Scientists participating in the project, DNA of twin children adjusted by a tool
Edit the powerful gene "CRISPR".

The world claimed that the two children, Lulu and Nana, were born weeks ago and were resistant to HIV infection.

He described
Researchers around the world consider it "irresponsible", in which they question
Many of them have moral and moral effects that are detrimental to them.

A British scientist, calling this experience "brutal", said researchers were playing a "serious game" with healthy children.

Genetic modification is a forbidden experience in Britain and the United States.
United Nations and many other parts of the world because of its long-term effects
On the mental and physical health is poorly understood, to a large extent.

That implies
This technique can cause the modified DNA to deform genes
Other potentially dangerous mutations can be pbaded on to future generations.

She said
Dr. Kathy Nyakan of the Francis Crick Institute in London: "If this is true
The report is disturbing. It would be irresponsible, immoral and dangerous
In terms of genome editing technology. Given the great uncertainties
Security issues, including the possibility of unwanted side effects,
It is premature to try to do it. "

Said Professor Julian Savolisco, Director of the Center
Uehiro of practical ethics at the University of Oxford, said the experiment exposed children
People in good health at the risk of genetic engineering "without any necessary benefit
Admittedly, this experience is brutal. "

Some scientists have called for the establishment of an international treaty on embryo research to prevent similar experiments in the future.

She said
Professor, Darwin Griffin, genetic scientist at Kent University: "In a world that is trying
In general, academics need to be aware of ethical issues
And the social that surrounds the work we do, this report brings us back to the times
Pierre. Scientists can not be seen as trying to go ahead in the absence
Ethical constraints ".

However, the world of genetics famous, professor
George Church, professor at Harvard University, defended the attempt to release the gene to prevent
HIV infection, which he describes as "a major threat to health"
Public. "

Dr. Giancoi explained that his goal of the operation was not to heal.
From genetic disease or prevention, but to try to give a trait not only appreciated
Few people, the ability to resist HIV infection
Human rights.

Monday, November 26 in Hong Kong, Khah announced his experience
The organizer of an international conference on the release of genes, is due to start on Tuesday 27
As well as in a special interview with Associated Press.

In
In recent years, scientists have discovered a relatively easy way to release genes, via a tool
Known as "CRISPR-cas9", allows work on the DNA to add a necessary gene
Or disable one of the factors causing health problems.

I did not try these
The only recent way to treat deadly diseases in adults, with all the restrictions
Genetic modifications, which means that patients can not transfer them to their children.

The release of sperm, eggs or embryos is different, the change and modification can be inherited.
