MiR-208
RNA family
From Wikipedia, the free encyclopedia
miR-208 is a family of microRNA precursors found in animals, including humans. The ~22 nucleotide mature miRNA sequence is excised from the precursor hairpin by the enzyme Dicer.[1] This sequence then associates with RISC which effects RNA interference.[2]

In humans, the gene for miR-208 is located in an intron of MYH7.[3]
Function
miR-208 has been deemed a "myomiR"[3] as it is specifically expressed, or found at much higher levels, in cardiac tissue. Other myomiRs include miR-1 and miR-133.[3] miR-208 is thought to be dysregulated in various cardiovascular diseases.[4][5]
miR-208 functions in cardiomyocytes regulating the production of the myosin heavy chain during development.[3] It also responds to stress and forms part of a hormonal signalling cascade in cardiac cells.[6]
Applications
A preliminary study has shown a potential use in the prognosis of dilated cardiomyopathy.[7] Another application has been suggested as using plasma concentration of miR-208 as a biomarker of damaged cardiac muscle cells.[8]
