Abstract 【Abstract】 Objective To characterize the genome-wide microRNA profile and to explore the biological functions and probable mechanisms for microRNAs in diamond-blackfan anemia （DBA）. Method Zebrafish embryos at the one-cell stage were injected with the Rps19 MO and Rps19+p53 MO. The miRNomes of these zebrafish models and control, generated by miRNA-seq, were compared for determining the microRNA profile characteristics of DBA and regulatory function of p53. Result Rps19 morphants showed an obviously ventrally bent tail and a reduction in the circulating blood cells compared with the control embryos, which werepartially rescued in Rps19+p53 MO at 48 hpf. By comparing the miRNomes with control, we found that about25% of total expressed microRNAs in Rps19 MO had significantly lower expression, which might make an influence on the development process of Zebrafish embryos. The abnormal miRNomes were partially reversed by simultaneous knockdown of p53. We determined 47 microRNAs that were potentially regulated by p53 in DBA pathologic process.Conclusion microRNAs in Zebrafish model of DBA were in an inactive state, which was partially affected by p53.
