miR-218 microRNA precursor is a small non-coding RNA that regulates gene expression by antisense binding. miR-218 appears to be a vertebrate specific microRNA and has now been predicted and experimentally confirmed in a wide range of vertebrate species. The extents of the hairpin precursors are not known. In this case the mature sequence in excised from the 5'arm of the hairpin. miR-218, along with miR-585, has been found to be silenced by DNA methylation in oral squamous cell carcinoma. It is also downregulated in Nasopharyngeal carcinoma, with artificially-induced expression serving to slow tumour growth. miR-218 has also been found to have tumour suppressing qualities in bladder cancer cells.
