Chinese Gene-editing scientist defends his research, poses the third child's choice


Second International Human Human Genome II Upon reaching 700 people on the summit, on Wednesday, Jianku publicly defended his work, felt his "proud" achievement.

Associate Professor of Science and Technology at the Southern University in Shenzhen, on Tuesday, a shocked wave of scientific community was sent to a video posted on video after the appearance of two boys after healthy girls who were born from HIV-positive embryos from HIV-positive resistance.

"In this particular case, I feel proud, I feel farther because they have lost their life expectancy," she said Wednesday, focusing on twin parents, so that her father can take HIV. "But with that support, (father) (he has sent a message, he will work hard to win money and take care of his two daughters and his wife."

Asked if he was pregnant with other clinical sessions about the genome editing, he replied: "There is another, another potential pregnancy."

The Academy did not give details of the third child's ability, as "yes" responded whether or not the pregnancy was initially asked.

He covered all the expenses related to the medical attention of the patients involved in this trial. He also admitted that some sequencing costs were covered by the initial university funding, although it could not be accepted as a "college".

He has sent his research to the scientific journal, not naming the journal's name, and asking for a pessimistic result of "unexpectedly".

Chinese scientists claim to be the first baby in the world, denial of hospital and international criticism

The research has created serious ethical questions regarding the transparency of the genetic edition and calls for global consensus, since the pace of genetic editing technologies exceeds the ability to make new laws or rules.

After the presentation, in the questionnaire response session, Both parents consented to two rounds, which lasted three hours, that is, how we explained that the CCR5 genes removed other vulnerable infections for children, such as the West Nile virus.

According to him, volunteers were found through a group of volunteers through HIV / AID.

However, many of the participants in the Hong Kong Congress have emphasized that while the global problem does not leave its activities illegally, its supposed CRISPR-cas9 indicates a clear step in the convention.

"It's a fairly consistent consensus on what is being edited by the genome and it's not acceptable, and it has been reported that work represents this outcome," said David R Liu, a chemistry and chemistry biology professor at Harvard University, CRISPR versions.

During the conference, aimed at managers of genetics, ethics and politicians, it is expected to publish a development statement on Thursday, closing session.

After the presentation, in David Baltimore's speech, the investigation was not medically necessary, because they were other treatments for HIV. Baltimore criticized the lack of transparency and covenant in the 2015 conference, said it would be negligible to use this genetic edition until it was treated with security problems.

China is the leader

China has been investing in technology genetic technology, and the government has done a research bankrolling study of the "first" of the world, and the first use of the CRISPR-Cas9 gene-edition tool CRISPR-Cas9 in 2016 and the first edition of gene editing technology reported in 2015 to change non-viable embryos.

Last year, China gained $ 1.76 trillion ($ 254 million) in research and development, and the country invested US investment with the same investment, giving a label called Sputnik 2.0 label. Carl June is a immunotherapy specialist at the University of Pennsylvania.

However, on a Monday interview, more than 120 Chinese scientists condemned the use of the CRISPR-Cas9 tool as a "great blow" for the Chinese biomedical research.

"The Chinese scientist who advocates the basic line of scientific science is the most unfair, innovative, and scientific leader," they wrote, "it is only a man who experiments directly as a human being … as a human being, no one influences to predict that the inheritable substance of the changes will inevitably be confused in the human genome pool. "

The Chinese government has also directed "immediate investigation" in its claims.

Government investigation continues The Hospital members are named On-label documents and they participate in the university to deny the implication in procedures.

In a separate development, Wednesday, after investigating Professor Michael Deem bioengineering at Rice University, he said he was involved in the media reports.

Deem Rice was a consultant for over three years and published three papers.

"This study questions scientific, legal and ethical questions," said Doug Miller, director of the Rice University media team. In a statement, Miller said "it's not the knowledge of this work."

Unknown effects

At the forefront of global concerns, genetic editing technology continues to be in childhood and the use of human embryos results in bad results.

Chinese scientists use human genetic techniques for the first time

Women's long-term social effects had a special concern at Hong Kong tops, and a member of the audience asked whether the girls would see themselves and how they would treat society.

"I do not know how to answer this question," he said.

Feng Zhang, one of the inventors of the genome edition of the CRISPR and member of the MIT and Harvard Institute Members, has called for a moratorium on the creation of CRISPR's protective genres.

"It is waking up to call more attention in the field," said the CNN speech on Wednesday. "These are not the things we need to do now."

Despite the ethical concerns, a new investigation has suggested that China's public support gender genres for medical purposes. An inventory of the Guangzhou Sun Yat-Sen University inventory has found that more than two thirds of 4,771 people (575 of them from HIV) use the treatment of illnesses, according to the Global Times newspaper.

"(People from China) has a great willingness to use the genes in the prevention and treatment of illnesses," said Liang Chen, Professor of Sun Yat-Sen University. "This suggests that Chinese research on editing genes is not a high potential hope, but responds to the needs of the public."
