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]

Contents

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 in breast cancer and endometriosis cells, resulting in a reduction of cell motility. [4] [5] Larsson et al. [6] showed that miR-145 targets the 3' UTR of the FLI1 gene, a finding that was later supported by Zhang et al. [7]

Role in cancer

miR-145 is hypothesised to be a tumor suppressor. [8] miR-145 has been shown to be down-regulated in breast cancer. [5] miR-145 is also involved in colon cancer [7] [9] [10] and acute myeloid leukemia. [11]
