摘 要:
microRNAs(miRNAs)是人类新发现的一类非编码小分子RNA,广泛分布于真核细胞内。miRNAs通过与靶基因互补位点配对结合,在转录后水平负性调控靶基因的表达,参与生长发育、细胞增殖、细胞凋亡、细胞分化等生命过程。据推测,大约1%的人类已知基因编码miRNAs,而miRNAs可调控人类基因组中10%-30%的基因。本文就如何识别miRNAs及其靶基因作一简要介绍。[著者文摘]

Abstract:
karyotes and microRNAs (miRNAs) are a recently discovered family of small non-coding RNAs, which exist in euregulate gene expression post-transcriptionally by binding to complementary sites MiRNAs play important roles in regulation of cell proliferation, development, apoptosis and cell on target mRNAs. differentiation. It' s predicted that about 1% human known genes encode microRNAs and microRNAs may regulate 10 - 30% of the genes in the human genome. The paper focus on the knowledge about how to recognize miRNAs and identify their target mRNAs.[著者文摘]
Key words:
microRNAs(miRNAs) ; non-coding RNA; target mRNA
