      【摘要】 MicroRNAs (miRNAs)是一种内源性的小 RNA分子,在基因的转录后能调节其表达。许多
MicroRNAs被证实与各种肿瘤相关,包括乳腺癌。某些抑癌性MicroRNAs的缺失和致癌性MicroRNAs的过表
达已经在许多乳腺癌中被发现。本文就MicroRNAs与乳腺癌发生发展之间的联系以及与一些乳腺癌相关的
MicroRNA及其作用作一综述。

【Abstract】 MicroRNAs (miRNAs) are a major class of small endogenous RNA molecules that post-transcription-
ally regulate gene expression. Several miRNAs have been proved to be related to human cancers, including breast cancer.
The loss of several tumor suppressor miRNAs and the overexpression of certain oncogenic miRNAs have been observed
in breast cancers. Here we describe the relationship of miRNA with the tumorigenesis and metastasis of breast cancer.
