mir-9/mir-79 microRNA precursor family

(Redirected from MiR-9)

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

edit

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

edit

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]
