In molecular biology, mir-145 microRNA is a short RNA molecule that in humans is encoded by the MIR145 gene. MicroRNAs function to regulate the expression levels of other genes by several mechanisms.[3]

Targets

MicroRNAs are involved in down-regulation of a variety of target genes. Götte et al. have shown that experimental over-expression of mir-145 down-regulates the junctional cell adhesion molecule JAM-A as well as the actin bundling protein fascin.[4] Larsson et al.[5] showed that miR-145 targets the 3' UTR of the FLI1 gene, a finding that was later supported by Zhang et al.[6]

Role in cancer

miR-145 is hypothesised to be a tumor suppressor.[7] miR-145 has been shown to be down-regulated in breast cancer.[4] miR-145 is also involved in colon cancer [6][8][9] and acute myeloid leukemia.[10]
