美国研究人员发现,一种生活在土壤中的致病细菌——诺维梭菌有可能成为新的抗癌辅助手段。这种微生物不仅让实验狗体内的肿瘤缩小了,对于人类肿瘤似乎也具有一定效果。诺维梭菌是一种常见的厌氧菌,其释放的酶可以穿透并杀死哺乳动物细胞。美国某生物科技公司的研究人员想弄清楚,是否可以利用这种细菌有选择性地杀死哺乳动物恶性肿瘤中的细胞。肿瘤组织中血行不畅,导致供氧不足,而这些细菌恰好喜欢缺氧环境。 US researchers found that a pathogenic bacterium that lives in the soil-Norovirus can be a new anti-cancer aids. This kind of microorganism not only makes the tumor in experimental dog reduce, but also seems to have a certain effect on human tumor. Clostridium nidulans is a common anaerobic bacterium that releases enzymes that penetrate and kill mammalian cells. Researchers at a biotech company in the United States want to find out whether it is possible to use this bacterium to selectively kill cells in mammalian malignancies. Poor blood flow in tumor tissue, resulting in lack of oxygen, and these bacteria just like hypoxic environment.
