  • Sobre la teoría de la relatividad especial y general - Albert Einstein September 26, 2017
    Entre el Electromagnetismo y la Mecánica newtoniana existe una fórmula de bisagra: la teoría de la relatividad especial y general. La importancia del nuevo marco planteado por Albert Einstein se entiende por lo siguiente: la percepción del tiempo y el espacio es relativa al observador. ¿Qué significa esto? Si usted viaja a una velocidad mayor que la de la lu […]

In Breakthrough, Scientists Edit a Dangerous Mutation From Genes in Human Embryos

“We’ve always said in the past gene editing shouldn’t be done, mostly because it couldn’t be done safely,” said Richard Hynes, a cancer researcher at the Massachusetts Institute of Technology who co-led the committee. “That’s still true, but now it looks like it’s going to be done safely soon,” he said, adding that the research is “a big breakthrough.”“What our report said was, once the technical hurdles are cleared, then there will be societal issues that have to be considered and discussions that are going to have to happen. Now’s the time.”Scientists at Oregon Health and Science University, with colleagues in California, China and South Korea, reported that they repaired dozens of embryos, fixing a mutation that causes a common heart condition that can lead to sudden death later in life.If embryos with the repaired mutation were allowed to develop into babies, they would not only be disease-free but also would not transmit the disease to descendants.The researchers averted two important safety problems: They produced embryos in which all cells — not just some — were mutation-free, and they avoided creating unwanted extra mutations.“It feels a bit like a ‘one small step for (hu)mans, one giant leap for (hu)mankind’ moment,” Jennifer Doudna, a biochemist who helped discover the gene-editing method used, called CRISPR-Cas9, said in an email.Gene Editing in EmbryosScientists tried two techniques to remove a dangerous mutation. In the first, genetic “scissors” were inserted into fertilized eggs. The mutation was repaired in some of the resulting embryos but not always in every cell. The second method worked better: By injecting the “scissors” along with the sperm into the egg, more embryos emerged with repaired genes in every cell.FIRST TECHNIQUEWhen gene-editing components were introduced into a fertilized egg, some embryos contained a patchwork of repaired and unrepaired cells.Gene-editingcomponents insertedafter fertilizationCell withunrepairedgeneMaternal DNAMutationSpermPaternal DNACell withrepairedgeneOocyteFertilized cellMosaicism inlater-stage embryoNEW TECHNIQUEWhen gene-editing components were introduced with sperm to the egg before fertilization, more embryos had repaired mutations in every cell.Gene-editing componentsinserted together with sperm,before fertilizationIn 42 of 58embryostested, allcells wererepairedUniformlater-stage embryoFIRST TECHNIQUEWhen gene-editing components were introduced into a fertilized egg, some embryos contained a patchwork of repaired and unrepaired cells.Gene-editingcomponents insertedafter fertilizationMaternal DNAMutationPaternalDNASpermOocyteFertilizedcellCell withunrepairedgeneCell withrepairedgeneMosaicism inlater-stage embryoNEW TECHNIQUEWhen gene-editing components were introduced with sperm to the egg before fertilization, more embryos had repaired mutations in every cell.Gene-editingcomponents insertedtogether with sperm,before fertilizationIn 42 of 58embryostested, allcells wererepairedUniformlater-stage embryo“I expect these results will be encouraging to those who hope to use human embryo editing for either research or eventual clinical purposes,” said Dr. Doudna, who was not involved in the study.Continue reading the main storyMuch more research is needed before the method could be tested in clinical trials, currently impermissible under federal law. But if the technique is found to work safely with this and other mutations, it might help some couples who could not otherwise have healthy children.Potentially, it could apply to any of more than 10,000 conditions caused by specific inherited mutations.
