Our findings were in consistent with studies using the hemin -treated K562s or EPO -induced CD34+ HPCs to differentiate into mature erythrocytes, revealing the upregulation of miR-23a, miR-27a or miR-24 during erythropoiesis, whereas an activin A -mediated erythroid mo dels reported the inhibitory role of miR-24 in haemaglobin accumulation. [score:6]
The aforementioned experiments suggested that in addition to effecting erythroid differentiation, upregulated GATA-1 bound and activated the miR-27a and miR-24 genes, which led to further repression of GATA-2 translation and facilitated GATA-1 replacement of GATA-2 at miRNAs promoter (Figure 6A). [score:6]
Here, miR-27a and miR-24 perform post-transcriptional protection through repressing the translation of GATA-2, which should not be expressed in differentiated erythroid cells. [score:5]
In contrast to miR-451 locus whose expression was restricted to the fetal liver in embryonic day (E) 16.5 mouse embryos, the major site of haematopoiesis and erythropoiesis at this stage of development, miR-27a and miR-24 seem to serve as universal regulators in different cell types. [score:5]
As expected, the percentage of benzidine -positive cells (Supplementary Figure S4A) and gamma-globin accumulation (Supplementary Figure S4B) increased in miR-27a or miR-24 over-expressed K562s, whereas the percentage of benzidine -positive cells decreased in K562s following the inhibition of miR-27a or miR-24. [score:5]
Increased GATA-2 expression led to a decrease in the levels of Pri-27a∼24 and mature miR-27a or miR-24 (Figure 5E), whereas GATA-2 knock-down increased the transcription and maturation of miR-27a and miR-24 (Figure 5E). [score:4]

Further, like the comparison between MiR23b and MiR24.1, expression of MiR206 was much weaker than the expression observed for MiR133b. [score:4]
We initially examined miRNA expression in E12.5 mouse embryo using whole mount ISH and LNA probes against Mir23b, Mir24.1, and Mir666 (Supplemental Figure 1). [score:3]
In mouse, Mir23b is part of a miRNA cluster that includes Mir23b, Mir27b, Mir3074.1, and Mir24.1. [score:1]
In zebrafish, this corresponds to mir23b, mir27d, and mir24.1. [score:1]

Intrigued by our results on the analysis of miR-24 and let-7 mutations, we reasoned that a comprehensive analysis of our mutagenized miRNA sequences would establish the most successful mutations to functionally perturb miRNA expression in vivo (Fig. 4A). [score:5]
Although wild type GFP-miR-24-MRE positive embryos showed overall homogenous expression of the GFP and mCherry proteins, mosaic derepression of the GFP-miR-24-MRE was only observed after co-injection of the multiplexed sgRNAs-Cas9 against the four miR-24 loci (Fig. 3B, arrows). [score:3]
In vitro transcribed GFP-miR-24-MRE and mCherry mRNAs were co -injected into one-cell stage embryos with and without the miR-24 multiplexed sgRNAs and Cas9 mixture. [score:1]
To test if the mutations reduced miRNA activity, we employed a miRNA gene reporter assay 26 (Fig. 3B) in which the coding sequence for green fluorescent protein (GFP) was cloned upstream and in frame with a 3′UTR containing three miRNA responsive elements (MRE) that were perfectly complementary to miR-24 (GFP-miR-24-MRE). [score:1]
Indeed, the injection of our CRISPR/Cas9 against the let-7 superfamily or miR-24 was sufficient to disrupt mature miRNA activity leading to derepression of a GFP sensor containing miRNA -binding sites. [score:1]

To evaluate the accuracy of the microarray screening and the miRNA profiling results, genes and miRNAs with change direction either down-regulated (plp1b, h3f3c and dre-mir-24-4-3p) or up-regulated (emx2, ikzf5, dazap, mmp13, zgc:112425, taldo1, and dre-mir-152-3p) were selected for quantitative RT-PCR verification.
