中文摘要：

非编码RNA是各种不作为翻译蛋白质的模板的RNA的统称,参与很多生命活动的调控并扮演着重要的角色。它们参与m RNA翻译、RNA剪切、化学反应催化,以及参与DNA复制修复、基因转录调控、发育和细胞分化调控等。现针对哺乳动物细胞内非编码RNA调控依赖于RNA聚合酶II,产物为m RNA的转录进行综述。

英文摘要：

Non-coding RNAs（nc RNAs） are RNA molecules that do not serve as template for translation. They participate in a myriad of biological processes and play crucial regulatory roles. Nc RNAs have been found to regulate translation and splicing, serve as ribozymes, modulate DNA replication and gene transcription, dictate development and cell differentiation. In this review, we focus on the regulation of nc RNAs in the transcription of RNA polymerase II in mammalian cells.
