越来越多的证据表明,某些获得性性状可以遗传给下一代。然而,获得性性状的遗传仍然存在争议,因为人们还不了解这一现象背后的确切分子机制。中国科学院动物研究所孙青原研究员领导的研究团队发现,环境能诱导精子发生表观遗传学改变,并且这种改变可以遗传到下一代。在全球范围内,前期糖尿病和二型糖尿病越来越普遍。此前人们已经发现,父亲的空腹血糖升高和糖耐受的降低,会影响后代的糖代谢,但研究者们还不清楚这些影响背后的确切分子机制。孙青原研究团队构建了环境诱导的前期糖尿
There is growing evidence that some acquired traits can be passed on to the next generation. However, the inheritance of acquired traits remains controversial because one does not yet understand the exact molecular mechanism behind this phenomenon. A team led by researcher Sun Qingyuan at the Institute of Zoology, Chinese Academy of Sciences, found that the environment can induce epigenetic changes in spermatogenesis that can be passed on to the next generation. Globally, pre-diabetes and type 2 diabetes are becoming more prevalent. It has been previously found that elevated fasting glucose and impaired glucose tolerance affect the glucose metabolism of the offspring, but the exact molecular mechanism underlying these effects is unclear to researchers.
