日本の科学技術の研究・開発の遅れは次第に決定的になっていくだろう

2017/9/29は、中国の科学者がヒトの受精卵を操作し遺伝病を終わらせることができるかもしれないとのニュースが伝えられています。海外ニュースでは中国の発明がときどき伝えられますが、日本の発明ではそのようなことはなく、むしろ福島第一原発事故現場の収束作業のモタツキが伝えられています。

日本の科学技術の研究・開発の遅れは次第に決定的になっていくのではないでしょうか。そんな恐れを感じます。

'Ingenious': Chinese scientists edit human embryo, could end hereditary disease
Chinese scientists have successfully altered the genetic code of a human embryo, an “ingenious” breakthrough that experts believe could be key to eradicating hereditary diseases.

Using a technique known as ‘base editing’, researchers from Sun Yat-sen University in Guangzhou filtered through three-billion ‘letters’ of our genetic code to remove a single error responsible for a potentially deadly blood disorder.

"We are the first to demonstrate the feasibility of curing genetic disease in human embryos by base editor system,”Junjiu Huang, one of the scientists involved in the research, told BBC.

During the experiments, which were carried out on tissues taken from a patient with the blood disorder beta-thalassemia and inserted into cloned human embryos, a strand of DNA was examined to pinpoint the offending base. The team then used base editing, a more advanced form of the Crispr gene-editing technique to repair the faulty gene.

Such is the level of precision involved in base editing that Professor David Liu of Harvard University, a pioneer of the technique, dubbed it “chemical surgery.”

“Base editing has the potential to directly correct, or reproduce for research purposes, many pathogenic [mutations]," Liu said, adding that it is more efficient than Crispr as it has fewer unexpected side-effects.
