In contrast, embryos injected with miR-141/429a inhibitors showed only 5.3% increase in body length, because the expression change of GH/IGF axis genes was more remarkable in embryos treated with miR-141/429a mimics than with their inhibitors (Fig. 5E). [score:7]
As the results, ectopic expression of miR-141 resulted in a reduction expression of GH and GHRb to 12.8% and 17.6% at 24 hpf, 11.2% and 66.4% at 48 hpf (Fig. 2C), while miR-429a reduced the expression of GH, GHRa, GHRb and IGF2a to 62.3%, 37.1%, 59%, 72% at 24 hpf and 20%, 14%, 6.5%, 52.5% at 48 hpf (Fig. 2D) compared to the control microRNA mimic. [score:6]

Comparing with the control -mimic injected embryos (Fig. 4C-a), ectopic expression of miR-141/429a resulted in significantly higher level of apoptotic cells in brain and tails (Fig. 4C-b) that could be rescued by the miR-141/429a inhibitors (Fig. 4C-c). [score:5]

Co-injection of either 10 μM miR-141/429a with 40 μM inhibitor or 20 μM miR-141/429a with 80 μM inhibitor produced a statistically significant recovery in length to 3507 ± 103 μm or 3480 ± 73 μm. [score:5]

Accordingly, we detected that expression of miR-141 and miR-429a were increased by injection of p53 mRNA into zebrafish embryos compared to the control groups (Fig. 6C), whereas the GH mRNA was reduced by ectopic expression of p53 (Fig. 6D). [score:4]
The results in our study suggest that over -expression of miR-141/429a may affect embryo heart development. [score:4]
However, injection of miR-141/429a inhibitors did not cause any observable developmental defects in zebrafish embryos, that was the same phenotype as injection of morpholinos of miR-200 family members 35 36. [score:4]
miR-141/429a repressed the luciferase activity of GH 3′ UTR-pmirGLO, whereas mutation of either predicted miR-200a/141 or miR-200b/200c/429a/429b binding site attenuated this repression, and mutation in both binding sites abrogated this repression (Fig. 5A). [score:3]
To check the expression of miR-200 family members during normal embryonic development, we synthesized cDNA with a mixture of stem-loop RT primers of miR-141/200a, miR-429a/429b and miR-200b/200c, respectively. [score:3]
For the following experiments, miR-141 and miR-429a mimics or inhibitors were 1:1 mixed to give working solutions. [score:3]
Among all three binding sites of miR-200s in GHRb gene, mutation of either binding site 1 or 3 attenuated the repression of luciferase activity by miR-141/429a, and mutation in both binding sites 1 and 3 abrogated this repression (Fig. 5B). [score:3]
In comparison to the control, overexpression of miR-141/429a increased percentage of cells in G1 (approximately 10.67%) and reduced percentages of cells in S (approximately 5.26%) and G2/M (about 5.42%) (Fig. 4A,B). [score:3]
To examine the ability of miR-200s inhibitors to repress miR-200s levels in vivo, we injected zebrafish embryos with anti-miR-141, anti-miR-429a or a scrambled control. [score:3]
Moreover, the inductions of both miR-141 and miR-429a by GH injection were abrogated in p53 mutant embryos, suggesting that p53 is necessary for the increased miR-200s expression by GH activation in zebrafish embryos. [score:3]
Taken together, our observations suggest that miR-141/429a inhibits cell proliferation and induces cell apoptosis. [score:3]
Moreover, the miR-141/429a inhibitors could efficiently rescue the defects of cell cycle arrest. [score:3]

Embryos injected with either miR-141/miR-200a or miR-200b/miR-429 pairs of antisense morpholinos showed lack of expression of the corresponding miR-200 members with a given 5′ seed but did not display any change in OMP expression relative to wild-type controls (data not shown). [score:5]
Finally, 8 of 24 miRNA probes, including miR-200a and miR-200b, as well as miR-96, miR-141, miR-182, miR-183, miR-191, and miR-429, revealed robust expression in the MOE and VNO neuroepithelium, with weaker expression in the adjacent respiratory epithelium (Figure 2A, right column, and Table S3). [score:5]
In addition, in situ hybridization analyses (Figure 7C) show that a mixture of all three morpholinos (Triple MO mix: miR-141 MO, miR-200b MO, and miR-429 MO) was sufficient to simultaneously inhibit the expression of all five mature zebrafish miR-200 family members to threshold levels of detection. [score:5]
As predicted from sequence analyses and thermal stability calculations, miR-141 MO specifically inhibited miR-200a and miR-141, miR-200b MO specifically inhibited miR-200b and miR-200c, and miR-429 MO specifically inhibited miR-429 (Figure S4B). [score:5]
However, miR-141 and -200a express different 5′ seed heptamers from miR- 200b, -200c, and -429 and are thus likely to form two functional subgroups within the miR-200 family (Figure 2C; Doench and Sharp, 2004; Lewis et al., 2005). [score:3]
One of these families, miR-200 family comprising miR-200a, miR-200b, miR-200c, miR-429, and miR-141, also highly detected by microarray, was among the most frequently cloned species in all olfactory tissues examined (Table S2). [score:1]
In mouse, the miR-200 family is composed of five family members (miR-141, -200a, -200b, -200c, -429) clustered into two loci of chromosomes 4 and 6 (Figure 2C). [score:1]
In order to test the specificity of each morpholino (MO) sequence, we systematically injected one-cell zebrafish embryos with either miR-141 MO, miR-200b MO, or miR-429 MO and performed in situ hybridization against all five miRNAs of the miR-200 family. [score:1]

miR-200a, miR-200b, miR-141 and miR-429 share the same seed sequence and likely target the same mRNAs; for this reason they are grouped in a single miR class (named miR-200-class). [score:3]
As a further confirmation, we carried out in situ hybridization on sections of WT and Dlx5 [−/−] embryonic OE, at the age E12.5, to detect miR-9, miR-141 and miR-429, using specific mouse DIG -labelled probes. [score:1]
