Chinese scientist would create the first genetically modified baby in the world


controversy and doubts, that's the prediction a Chinese scientist would create the first genetically modified baby in the world so resistant to some diseases, using it technique of genetic editing CRISPR.

The controversy began in specialized magazines, such as the American Magazine Review MIT Technology They studied the scientist He was JiankuiWhen videos began on YouTube, twins genes were modified on Sunday, November 25.

According to Chinese researchers, girls, Lulu and Nana "Some weeks ago they were healthy", Thank you in vitro fertilization Genetic modification of technology "that will prevent them from becoming infected with HIV."

In one of these videos, he uses the Crispr / Cas9 technique and justifies the experiment, the genetic change "It does not have the objective of eliminating genetic diseases"But" to give girls natural ability to do it hold one Possible HIV infection".

To achieve this goal, the CCR5 gene has been "deactivated", which forms a protein that allows the incorporation of a HIV into a cell and, in practice, involves the improvement of DNA.

"I think my work is controversial, but I think the families are willing to accept that technology and accept criticism," he says in one of the videos.

University "shocked"

However, Southern Science and Technology University from the city Shenzhen On Monday, November 26, the teacher appeared in a statement and emphasized I did not even know about this project.

The organization said "Surprised by deep case"And he demanded, as soon as he left this February, to explain as soon as possible.

"The University will be held international experts to investigate this incident, this is serious ethics violations and academic standards"He was told about the project organization, which also questions his opinion, since he has not been published in the scientific journals today.

On the other hand, the press China On Monday, he acknowledged that academic and citizen investigations sparked controversy throughout the country.

newspaper China He worries about "ethical issues and their effectiveness" about day-to-day problems, and reveals that both parents of children are HIV-positive, referring to a non-governmental organization led by Bai Hua, head of Baihualin.

Ethical question

Meanwhile, more than 120 academics of academics China said Sina Weibo, an assertion given by a China-based Chinese equivalent of Twitter, that "any attempt" of human embryos changes through "genius" genetic modifications when babies are born "at high risk."

"The government must take it quick legal measures to oversee this investigation rigorously ", added Chinese scientists.

The controversy also coincides with the beginning of an important meeting to change the genome that will take place from today's researchers on November 27-29, Hong Kong.

Overall, Nature Magazine, on November 26, discussed the debate and an article that argued that the announcement "wrath"Between the scientific community international and, if true, "it would be a significant leap forward in the use of the human genome".

"It's morning, dangerous and irresponsible," said Joyce Harper, a researcher at University College London.

"The experiment explains the child with normal and healthy risks without real benefits", emphasizes the magazine.

As nature suggests, this type of instrument has been used so far to underlie the responsibility of the mutation that causes the disease to exploit its benefit and has created ethical guidelines for the scientific community "for a long time". This would be a case like this.

In 2016, a group of Chinese scientists were pioneers in human beings, specifically with lung cancer patients, with genetic changes with Crispr technology, according to Nature magazine.

However, scientists from the UK have found that Crispr's gene technology can damage cells, according to a study published in the journal.
