The miR-192 microRNA precursor (homologous to miR-215), is a short non-coding RNA gene involved in gene regulation. miR-192 and miR-215 have now been predicted or experimentally confirmed in mouse and human.[1][2]

microRNAs are transcribed as ~70 nucleotide precursors and subsequently processed by the Dicer enzyme to give a ~22 nucleotide product. In this case the mature sequence comes from the 5' arm of the precursor. The mature products are thought to have regulatory roles through complementarity to mRNA.[3]

mir-192 and mir-215 are thought to be positive regulators of p53, a human tumour suppressor.[4] They are also overexpressed in gastric cancer, and could potentially be used as biomarkers or therapeutic targets.[5] It has also been suggested that mir-192 could be used as a biomarker for drug-induced liver damage.[6]
