MicroRNAs (miRNAs), such as MIR486-1, are small, non-coding RNAs that play key roles in the post-transcriptional regulation of gene expression by targeting specific mRNAs. MIR486-1 is highly conserved among mammals and is located on chromosome 8p11 within the Ankyrin-1 (ANK1) gene. It encodes two mature miRNAs, miR-486-3p and miR-486-5p. Alteration of both isoforms has been linked to cancers. In the haematopoietic system, both isoforms are strongly expressed in primary adult erythroid cells. Mounting evidence suggests that miR-486-3p plays a key role in the process of erythroid differentiation and foetal haemoglobin (HbF) regulation. miR-486-3p expression correlates with increased HbF synthesis in erythroid cells of beta-thalassaemia patients. miR-486-3p directly targets BCL11A [GeneID: 15], a known HbF repressor, by binding to the extra-long isoform of BCL11A 3′UTR, thereby affecting γ-globin gene expression. Therapeutic approaches that increase the HbF concentration have great potential for ameliorating the clinical and haematologic severity of beta-thalassaemia and other beta-haemoglobinopathies.
