【编译】《Oncogene》基于RNA干扰的哺乳动物细胞功

全基因组的序列测定已经为科研人员提供了非常丰富的信息,以研究基因组的组织、遗传的不稳定性、多态性以及具有潜在表达的基因。人类基因组所有基因的鉴别为利用小干扰RNA(siRNAs)和短发夹状RNA (shRNAs)进行大规模系统性基因沉默打开了大门。 随着 siRNA和 shRNA表达库的发展,利用RNA干扰技术去赋予肿瘤基因以功能并描述正常细胞基因转染后以及转化细胞的分子通路,将对开展新的和促进现有肿瘤治疗途径产生重大意义。

reverse genetics coming of age

Sequencing of complete genomes has provided researchers
with a wealth of information to study genome organization,
genetic instability, and polymorphisms, as well as a
knowledge of all potentially expressed genes. The
identification of all genes encoded in the human genome
opens the door for large-scale systematic gene silencing
using small interfering RNAs (siRNAs) and short hairpin
RNAs (shRNAs). With the recent development of siRNA
and shRNA expression libraries, the application of RNAi
technology to assign function to cancer genes and to
delineate molecular pathways in which these genes affect
in normal and transformed cells, will contribute signifi-
cantly to the knowledge necessary to develop new and also
improve existing cancer therapy.
