加拿大某大学健康科学中心进行了一次利用病毒治疗癌症的研究。研究发现,很多人体肿瘤中都存在致癌基因的Ras通道激活的现象,而呼吸道和胃肠道病毒能够感染和杀死那些带有激活的Ras信号通道的细胞。同此研究人员便考察这种病毒是否用于破坏肿瘤细胞。目前,动物实验结果给予了肯 A University of Canada Health Sciences Center conducted a study using viruses to treat cancer. Studies have found that many human tumors have Ras channel activation of oncogenes, while respiratory and gastrointestinal viruses can infect and kill those cells with activated Ras signaling pathways. The researchers also examined whether the virus was used to destroy tumor cells. At present, the results of animal experiments give Ken
