致癌病毒

他认为，肿瘤细胞，如果它们载有致癌病毒，应港湾病毒DNA整合到它们的基因组。

He assumed that the tumour cells , if they contained an oncogenic virus , should harbour viral DNA integrated into their genomes .

结论血清HBsAg阳性与食管癌发病显著相关，乙型肝炎病毒不仅是原发性肝癌的致癌病毒，还可能是食管癌致癌病毒之一。

Conclusion The occurrence of esophageal cancer was significantly associated with positive serum HBsAg . Hepatitis B virus ( HBV ) is not only the cause of primary hepatic carcinoma but may be one of the important risk factor for esophageal cancer .

这说明，L783小鼠白血病病毒基因组中不含有致癌病毒基因，此病毒属于慢性致瘤性逆转录病毒。

The results indicated that there was no oncogene in L783-MuLV genome , L783-MuLV belonged to slow oncogenic virus .

由于免疫抑制和致癌病毒的感染，实体器官移植受者患癌症的风险有所增高。

Context Solid organ transplant recipients have elevated cancer risk due to immunosuppression and oncogenic viral infections .

其机理除了应用免疫抑制治疗所带来的后果外，也不能忽视移植术本身带来的影响，如癌基因嵌合、致癌病毒的转移等。

Besides the outcome of immunosuppression , the effects of transplantation itself , such as oncogene chimera , transition of carcinogenic virus and so on , can not be neglected .

美国癌症学会声称，政府应在预防癌症发病和死亡的增长上有所作为，一是建议为贫穷和发展中国家提供疫苗，以预防致癌病毒的感染，比如乳头瘤病毒就是一种致癌病毒，可以引发妇女宫颈癌。

The American Cancer Society says governments can do things to help prevent the increase in cancer cases and deaths . One idea is to provide poor and developing nations with vaccines that help to prevent some cancer-causing infections . One example of a cancer-causing infection is human papillomavirus . This virus can cause cervical cancer in women .
