MicroRNA involvement in metastasis and recurrence of breast Cancer / 国际外科学杂志

ABSTRACT

MicroRNAS( miRNAs) are a class of single strand, small non-coding RNAs about 22 nucleotides, which have the function to regulate gene expression post-transcriptionally and control the biological processes,such as proliferation, differentiation and apoptosis. Recent studies indicate that miRNA plays an important role in tumor involved in invasion and metastasis. This article mainly reviews the feature of miRNA and its effect in metastasis or recurrence of breast cancer.
