Mir-9/mir-79 microRNA precursor family Precursor microRNA family
The miR-9 microRNA (homologous to miR-79), is a short non-coding RNA gene involved in gene regulation . The mature ~21nt miRNAs are processed from hairpin precursor sequences by the Dicer enzyme. The dominant mature miRNA sequence is processed from the 5' arm of the mir-9 precursor, and from the 3' arm of the mir-79 precursor. The mature products are thought to have regulatory roles through complementarity to mRNA .[ 1] In vertebrates, miR-9 is highly expressed in the brain, and is suggested to regulate neuronal differentiation.[ 2] A number of specific targets of miR-9 have been proposed, including the transcription factor REST and its partner CoREST.[ 3]
Species distribution
miR-9 has been identified in Drosophila (MI0000129 ),[ 4] mouse (MI0000720 ) and human (MI0000466 ),[ 5] and the related miR-79 in C. elegans (MI0000050 ) [ 6] and Drosophila melanogaster (MI0000374 ).[ 7]
Role in disease
microRNAs have been implicated in human cancer in a number of studies. It has been shown that human miR-9 expression levels are reduced in many breast cancer samples due to hypermethylation an epigenetic modification.[ 8] Hildebrandt et al . show that two genes encoding for has-miR-9 are significantly hypermethylated in clear cell renal carcinoma tumours.[ 9]
