MiR 451 is highly conserved in vertebrates and regulates erythrocyte maturation  where it becomes the most abundant miRNA. However  the basis for the non canonical biogenesis of miR 451 is unclear. In this study we tested the hypothesis that miR 144 represses Dicer in a negative feedback loop during erythropoiesis and enhances miR 451 biogenesis. Loss of miR 144 mediated Dicer repression in zebrafish embryos and human cells leads to increased canonical miRNA production and impaired miR 451 maturation.", null, null, null, null, "miR 144 mutant", null, "isolate:Lab reared|age:2 days|sex:not applicable|tissue:peripheral blood|genotype:miR 144 / |phenotype:wild type|treatment:n1|BioSampleModel:Model organism or animal", null, null, null, null, null, null, null, null, "Small RNA from peripheral blood from 2 dpf zebrafish embryos  miR 451 mutant", "sRNA Mut miR 144", "sRNA Mut miR 144", "Small RNA libraries were prepared from total RNA 0.5 g isolated from peripheral blood of wild type WT and miR 144 /  embryos at 48 hpf Small RNAs were size selected in 10% denaturing polyacrylamide gel in 1X TBE in range from 18 to 75 bp.
