纽约Ｓｌｏａｎ－Ｋｅｔｔｅｒｉｎｇ癌症研究中心的研究人员通过对实验鼠的研究发现，一种已经查明与人体肿瘤有关的突变基因可以促使免疫系统向人体器官发起攻击。 他们发现，在正常情况下，这种被称为ＰＴＥＮ的基因通过杀死能形成肿瘤的异常细胞来抑制肿瘤的生长。但是，一 Researchers at the Sloan-Kettering Cancer Research Center in New York City have found through research on experimental mice that a mutated gene that has been identified in relation to human tumors can prompt the immune system to attack human organs. They found that, under normal conditions, this gene, called PTEN, inhibits the growth of tumors by killing abnormal cells that can form tumors. However, one
