Recognition of microRNAs and its-targeting genes / 基础医学与临床

ABSTRACT

microRNAs (miRNAs) are a recently discovered family of small non-coding RNAs, which exist in eukaryotes and regulate gene expression post-transcriptionally by binding to complementary sites on target mRNAs. MiRNAs play important roles in regulation of cell proliferation, development, apoptosis and cell 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.
