A Chinese man says he has changed a number of situations in fertility cures, and who's already married couples. But there is a warning in the scientific community.
A Chinese researcher says they helped to create a & # 39; Firstborn, genetically-developed couples born this month, saying that DNA is changing with a new powerful device capable of rewriting the original life project.
If it were true, it would be a great jump for science with a great influence on values.
A US scientist said he was involved in genetic editorial work in China, which was banned in the United States because changes in DNA can be given to future generations and there is a danger that another gene will be damaged.
Many scientists believe that it is too dangerous to try, and some say that the Chinese report is the same as having a " try people.
Future revitalization of HIV disease
The researcher, He Jiankui of Shenzhen City, said he changed embryos for seven couples during a healing treatment, and so far he found a fertility. He said he did not aim to cure or cause healing disease, but to try to give an indication that there are very few people in a natural way: ability to prevent infection at this time Future with HIV, & # 39; virus causing AIDS.
He noted that the parents involved were refused to be identified or interviewed, and did not reveal where they were living or where the work was done.
Not yet confirmed by science
No one has confirmed anything He says independently, and was not published in a magazine, where other experts would be investigating. He named his work in Hong Kong Monday to one of the international conference organizers on genetic preparations that begin on Tuesday, and previously in a special interview with The Associated Press.
"I feel there is a strong concern not just about doing something for the first time, but also about setting the example," said the AP. & # 39; & # 39; Society decide what to do next & # 39; in terms of licensing or a & # 39; prohibit progress like that.
Over 120 Chinese scientists commented on his co-worker He Jiankui about the birth of two modified babies gently to prevent HIV, in an open letter in which they say that tests "humans" and affecting adverse effects.
The text was signed by scientists from a variety of centers, including the Tsinghua, Beijing and Fudan universities and the Chinese Academy of Sciences.
"The unpredictable transformations of human genetic material, which are very insecure in science, are the combination of a human genetic group," said the DPA published.
Researchers say "it is possible that babies are born healthy for a while, but the dangers and damages of a human body (…) same. "
They also regretted that the test is a "hard hit on the global reputation of Chinese science", and he asked that the scrutiny authorities would make as soon as possible and that they would investigate his / her; case.
"The Pandora box was opened and it may be possible to close us before damaging their damage," they warned.
However, a famous genealogist, George Church of Harvard University, advocated the genetic development of HIV, which he explained as "a growing and important threat to the health of the public . "
"I think it's easy to give," said Church about that goal.
In recent years scientists have found a simple comparative method for generating gene, DNA sequences that manage to; body. The machine, CRISPR-cas9 is named, which enables the # 39; DNA jobs provide a necessary generator or a person who defends problems that cause problems.
One of the people who found the CRISPR-Cas9 generator editing system, the American Jennifer Doudna, criticize his story.
"If it proves, this work is a breach of the pre-care and clear approach to the global scientific community application CRISPR-Cas9," said Doudna, professor of Chemistry and Molecular Biology and Stone at the University of California in Berkeley.
Doudna said that Elizabeth's research was not published or researched by his / her scientific community.
The researcher participates in Hong Kong of the Summit Edition Human Genomic, which he also plans to attend.
If scientific analysis is to consolidate this work, it will prove "the need to constrain the use of genetic genes in human situations to situations where there is no clear medical need in the cover and in which there is no other medication method possible, "he said.
The CRISPR-Cas9 system has been recognized for almost three decades and in 2003, the Spanish microbiologist Francisco Martínez Mojica found that the micro-organs used to protect themselves, and generating genetic material from viruses and including that material into their own DNA.
Mojica found the founder of Doudna and French researcher Emmanuelle Charpentier, years later, to make the system voluntarily reconfigured and recommended in 2012 that it could be used to generate the genome change directly, also people.
