据《科技日报》报道,美国华盛顿州立大学日前一项新研究发现,在美国广受欢迎的除草剂阿特拉津(Atrazine)对受污染哺乳动物的表观遗传影响巨大。大鼠实验发现,其不良影响会隔代遗传,造成第二代甚至第三代大鼠更易患上多种疾病。华盛顿州立大学生物学教授迈克尔·斯金纳和同事发现,怀孕的雌性大鼠曝露于阿特拉津污染后,其生育的大鼠(第一代)除体型较小外,并不会显示出其他不良影响,但第一代大鼠的后代,会表现出严重的发育异常,不仅体
A new study by Washington State University recently found that Atrazine, a popular herbicide in the United States, has a huge impact on the epigenetic behavior of contaminated mammals, according to a report in the Science and Technology Daily. Rat experiments found that its adverse effects will be transmitted from generation to generation, resulting in second-generation and even third-generation rats are more susceptible to a variety of diseases. Michael Skinner, a professor of biology at Washington State University, and his colleagues found that pregnant rats (first generation), except their smaller ones, did not show any signs of exposure to atrazine contamination Other adverse effects, but the first generation of offspring rats, will show serious dysplasia, not only the body
