Especialistas estudiar\u00e1n un nuevo m\u00e9todo destinado a modificar los organismos y acelerar la transmisi\u00f3n de genes transg\u00e9nicos dentro de las poblaciones de especies de reproducci\u00f3n r\u00e1pida, como los mosquitos, y que tiene el potencial de prevenir la propagaci\u00f3n de enfermedades y plagas de cultivos. Algunos cient\u00edficos creen que el uso de esta tecnolog\u00eda, por el contrario, puede traer consecuencias negativas.<\/strong><\/span><\/p>\n

La Academia Nacional de Ciencias de EE.UU. ha iniciado una revisi\u00f3n amplia del m\u00e9todo, denominado ‘gene drives’. Un\u00a0grupo de 27 reconocidos genetistas pidi\u00f3\u00a0estrictos controles sobre c\u00f3mo se utiliza la tecnolog\u00eda en laboratorios con el fin de minimizar los riesgos de un escape involuntario con consecuencias perjudiciales, public\u00f3 el diario ‘The Independent’<\/a>. …………<\/span><\/p>\n

…………. Los investigadores han comparado la tecnolog\u00eda gen\u00e9tica<\/a>\u00a0con una reacci\u00f3n nuclear en cadena, ya que permite que los genes, una vez modificados, se amplifiquen dentro de una poblaci\u00f3n de insectos u otros animales sin ninguna intervenci\u00f3n adicional.\u00a0Los experimentos de laboratorio en moscas de la fruta han demostrado que un gen modificado introducido en una mosca fue suficiente para ‘contagiar’ pr\u00e1cticamente a todas las moscas de\u00a0la poblaci\u00f3n reproductora tan solo despu\u00e9s de unas generaciones.<\/span><\/p>\n

Incluso el uso bien intencionado [del m\u00e9todo] puede tener consecuencias adversas graves. Por ejemplo, los mosquitos gen\u00e9ticamente modificados<\/a>\u00a0para ser resistentes a los virus podr\u00edan conducir a la evoluci\u00f3n de los virus hasta que sean m\u00e1s virulentos. Esto podr\u00eda conducir a la propagaci\u00f3n incontrolada de enfermedades mortales graves\u00bb, opina Helen Wallace, de la organizaci\u00f3n GeneWatch UK.<\/span><\/p>\n

Specialists consider a new method to modify the agencies and speed up the transmission of transgenic genes within populations of species of rapid reproduction, such as mosquitoes, and that has the potential to prevent the spread of diseases and pests of crops. Some scientists believe that the use of this technology, on the contrary, can bring consequences<\/span><\/p>\n

The National Academy of Sciences of the USA has initiated a comprehensive review of the method, called ‘gene drives’. A group of 27 recognized geneticists called for strict controls on how technology is used in laboratories in order to minimize the risk of an unintentional escape with damaging consequences, published the newspaper ‘The Independent’.<\/span><\/p>\n

Researchers have compared the gene with a nuclear chain reaction technology, since it allows that once modified, the genes are amplified within a population of insects or other animals without any additional intervention. In fruit fly lab experiments have shown that a modified gene introduced into a fly was enough to ‘infect’ virtually all the flies of the spawning only after a few generations.<\/span><\/p>\n

Even well-intentioned use [of the method] may have serious adverse consequences. For example, genetically modified to be resistant to the virus mosquitoes could lead to the evolution of the virus until they are more virulent. This could lead to the uncontrolled spread of serious life-threatening diseases\u00bb, says Helen Wallace, of the Organization GeneWatch UK.<\/span><\/p>\n
