Chinese geneticists changed the human genome
Chinese scientists said that they for the first time in history, failed to make changes in the genetic code of human embryos. About it reports The Verge.
The research team from sun Yat-sen University in Guangzhou managed to replace the DNA region responsible for the development of serious diseases. The potential interference of this kind may eventually lead to cure many genetic diseases and even to give humanity an opportunity to adjust the appearance and intellectual shortcomings of the child before birth.
According to scientists, to work used of a zygote that could develop into a viable fetus. In this case, from 86 zygotes in the process survived only 71, and of the survivors only four were able to replace the "problematic" part of the DNA. As a result, scientists have recognized the used technology is too raw.
The work caused controversy about the ethical aspect of the question, because the change of the human genome in many countries is banned, and the research is conducted mainly outside Europe and the USA.
As reports the edition about science, N+1, the largest scientific journals Nature and Science refused to publish the research results of Chinese scientists. As a result, it came out on the pages of Protein & Cell, Nature released a brief overview and pointed to the renewal of the ethical debate.
In the winter of 2014 Chinese researchers have published data to edit the genome of monkeys, who also managed to change at the level of the zygote. The effectiveness of the procedure was significantly higher and led experts to speak of a breakthrough in genetics. Published
