Behind genetically engineered babies, a Chinese scientist protects his research


Speaking to a crowd of about 700 people at the Second International Summit on Human Genome editorial Wednesday, She said she was proud of her work.

A professor at the South University of Science and Technology in Shenzhen, in his laboratory, has developed an embryo gene using a device known as CRISPR-cas9, which can be inserted or disconnected from certain genes for seven couples intending to fertilize an individual.

In a video posted on YouTube on Monday, he said that two of the twin two girls were born with DNA "to be resistant to HIV several weeks ago."

"For this extraordinary occasion, I am proud and I am proud of it because they lost hope in life," he says, referring to the parents of twins who consider his father to be HIV-positive.

"But with this protection, he sent a message that he (father) worked hard, earned money and cared for two daughters and a wife."

Jankuui is in the second international summit to edit the Human Genome in Hong Kong on November 28, 2018.

She thanked her school at the University of Southern Science and Technology in Shenzhen, "although they did not know about the research," he said.

When asked about the costs, he announced that he would cover all costs associated with the medical care of patients. He also acknowledged that some of the sequestration costs were covered by the university's initiated funding.

According to him, his research did not give a name to the publication in the scientific journal, but was sent for examination and apologized for the "unexpected" outcome.

Chinese scientist confirms that he has abandoned the world's first gene-generating infant and hospitalized internationally

The research has created important ethical questions about the transparency of gene editing and calls for a global consensus because the pace of genetic processing technology exceeds the potential for new laws and regulations.

The post-presentation questionnaire explains that it could be infected with other infections, such as the West Nile virus, by removing a two-round agreement with parents, including a gene called CCR5. The agreed form of agreement does not refer to this.

Volunteers were found in the Volunteer Group of HIV / AIDS, "he said.

However, although most participants in the Hong Kong conference did not have global rules prohibiting His behavior, the use of the alleged CRISPR-cas9 is a real break in the convention.

David L. Lee, Professor of Chemistry and Chemistry Biology at Harvard University, says: "There is a very consensus about what is happening in the processing of genomes and what their work means to get out of it." CRISPR versions.

The conference, with the participation of leaders in the field of genetics, ethics, and policymaking, is expected to make a statement on Thursday at the closing session.

According to David Baltimore, chairman of the conference, there is no need for research because there are other forms of HIV-infection. Baltimore tested his lack of transparency and stated that it would not be liable for such a genetic correction until the 2015 security issue was resolved.

China is a leading player

China has invested a lot of money in gene-editorial technology, initially studying the world's first "first" banks, including the use of the 2016 CRISPR-Cas9 human-editing tool for the first time. Changing Human Embryo In 2015

China spent a record $ 1.76 trillion yuan ($ 254 billion) in research and development last year, and the US has boosted American investments in that area and triggered the so-called "Sputnik 2.0" genetic arms race. Carl Jones, immunotherapy specialist at the University of Pennsylvania.

In a joint statement released Monday, more than 120 Chinese scientists accused the use of the CRISPR-Cas9 as a "bulky" blow to China's biomedical research.

They wrote that "not just a person who experimented with experiments, it is not reasonable … after the emergence of a living person, no one is there." They said: "Very unjust to Chinese scientists defending the low level of innovation and scientific ethics" could predict what effect it would have, because the heterogeneous inheritance would undoubtedly intervene in the human genome pool. "

The Chinese government also demanded "immediate investigation."

In the Government's investigation, he oversees the attempts by the University and the university to exclude the participation of the university in the documents referred to in the Ethics Code.

As Rachel University developed on Wednesday, she was researching bioengineering professor Michael Dym, as he was doing his work on media reports.

He has been Rice's advisor for more than three years and has published three articles.

"This study raises scientific, legal and ethical issues," said Doug Miller, Rice University Media Relations Group director. In his statement, Miller said that Rice "did not know this job."

Unknown effects

In the foreground of global challenges, the gene processing technology is still older and can have great unknown consequences that can be brought to human embryos.

For the first time, Chinese scientists use genetic-editorial techniques

Gene editorial technology CRISPR and MIT and member of the Harvard Institute, Feng Zhang, demanded a moratorium on the use of CRISPR to edit gene genes.

"You have to be upset to get out of the square," CNN TV channel told a Wednesday conference. "This is not something we should do right now".

Despite ethical issues, recent research has suggested that the Chinese would be able to widely use their medical gene-editoriality. According to a survey conducted by the Sun Yat-Sen University in Guangzhou, two-thirds of the 4,771 surveyed people (including 575 HIV-infected) have responded to the treatment, reports The Global Times.

"People in China want the use of gene in the prevention and treatment of diseases," said Lian Ceng, a professor at Sun Yat-Sen University. "This study of gene processing in China is not only a prospective potential, but also meets the needs of the people."
