mir-130 microRNA precursor family
|mir-130 microRNA precursor family|
|RNA type||Gene; miRNA|
In molecular biology, miR-130 microRNA precursor is a small non-coding RNA that regulates gene expression. This microRNA has been identified in mouse (MI0000156, MI0000408[permanent dead link]), and in human (MI0000448, MI0000748[permanent dead link]). miR-130 appears to be vertebrate-specific miRNA and has now been predicted or experimentally confirmed in a range of vertebrate species (MIPF0000034). Mature microRNAs are processed from the precursor stem-loop by the Dicer enzyme. In this case, the mature sequence is excised from the 3' arm of the hairpin. It has been found that miR-130 is upregulated in a type of cancer called hepatocellular carcinoma. It has been shown that miR-130a is expressed in the hematopoietic stem/progenitor cell compartment but not in mature blood cells.
