摘 要:微小RNA (miRNA)是近年来发现的一类内源性的、进化上高度保守的非编码单链小RNA,长度约为19~25个核苷酸,主要通过特异性识别并结合靶基因mRNA,抑制其翻译或者直接降解靶基因,在转录后水平调控基因表达。近来研究表明,miRNA在乳腺癌的侵袭和转移中发挥重要的作用,并有望成为乳腺癌预后评估的新型的潜在分子标志物。 |

Abstract:MicroRNAs (miRNAs) are a class of highly conserved small non-coding endogenous RNA molecules that are recently discovered,approximately 19~25 nucleotides in length and regulate the gene expression post-transcriptionally mainly by sequence-specific base pairing on the target mRNA,resulting in inhibition of protein translation or degradation of target mRNAs. Recently,it has been demonstrated that miRNAs play important roles in breast tumor invasion and metastasis,and may have potential to serve as novel prognostic biomarkers for breast cancer. |
