RNA干扰在宫颈癌HPV16E6/E7中的研究进展

Advances of RNAi in HPV16 E6/E7 of cervical cancer

RNA干扰（RNAi）是一种有效的基因沉默过程,宫颈癌的重要基因型HPV16的关键致癌基因是E6和E7,目前RNAi在HPV16 E6/E7中的基因沉默作用已取得一些突破性进展.在体外研究方面,正在进一步确定稳定干扰目的 基因的载体形式和筛选更好的干扰序列,在体内研究方面,已建立相应的动物模型,为RNAi的临床研究打下了铺垫.

RNAi is a process of effective gene silencing. Human papillomaviruses 16 （HPV16）, as the most prevalent genotype of cervical cancer, encodes the E6 and E7 oncogenes, which is pivotal for maintenance of malignant phenotypes. Recently, some significant advances have been obtained in RNA interfering effect on HPV16 E6/E7. In vitro, it has been developed more effective vector systems and screened for more specific targeted sequences. In vivo, the corresponding animal models have been established, which lay a good foundation for the clinical research.
