一项基于小鼠的研究显示:锯齿状息肉的形成依赖于肠道细菌。根据3月3日出版的《实验医学杂志》(TJEM)上的一项研究显示,肠道微生物的变化能彻底影响某些肠道肿瘤的形成。采用基因工程技术(转染基因、过表达生长因子HB-EGF),纽约西奈山医学院的研究人员在小鼠盲肠诱发出了锯齿状息肉。但是,研究人员发现,基因不是导致息肉发生的全部原因,
A mouse-based study shows that serrated polyp formation depends on gut bacteria. According to a study published in the March 3 issue of the Journal of Experimental Medicine (TJEM), changes in gut microbiota can profoundly affect the formation of certain intestinal tumors. Researchers at Mount Sinai School of Medicine in New York induced jagged polyps in the cecum of mice using genetic engineering (transfection of gene, overexpressing growth factor HB-EGF). However, researchers found that genes are not the entire cause of polyps,
