| 中文摘要: |
| microRNA(miRNA)是一类非编码的小分子单链RNA，主要通过转录后抑制靶基因表达调节各种生物功能。miRNA 表达水

未完全阐明。miRNA 基因转录后在大蛋白复合体的介导下经一系列协调加工过程形成成熟的miRNA。近来发现转化生长因子β
（TGFβ）信号途径的转导因子Smad 蛋白在细胞核内调节miRNA 的加工处理过程起重要作用。本文主要综述TGFβ/Smad 信号途

| 英文摘要: |
| MicroRNAs (miRNAs) are small, non-coding and single-strand RNAs which modulate diverse biological function
through post-translational repression of target gene expression. The levels of miRNAs are altered during normal development and pathogenesis
of various diseases, including cancer and cardiovascular diseases. However, the signaling pathway controlling miRNA biogenesis
and the regulating mechanism are not fully elucidated. Following transcription, mature miRNAs are produced through a series of coordinated
processes mediated by large protein complexes. Recently the Smads, the signal transducers of the transforming growth factor β
(TGFβ) signaling pathway, are found to play an important regulatory role in the processing of miRNA. In the present review, we mainly
summarized the regulatory effects of the TGFβ/Smad signaling pathway on miRNA biogenesis. |
