摘要

采用计算方法鉴定参与Salmo salar基本生物学过程的巨噬细胞特异性mirna。对大西洋鲑鱼(Salmo salar)感染沙门氏气单胞菌后巨噬细胞的1119个ESTs进行分析,发现有3个miRNAs表达。对这两个前mirna序列的系统发育分析揭示了其在不同物种间的进化保守性。预测miRNA的鉴定目标揭示了miRNA在组蛋白的发病机制、应激反应和变构交换中的作用。对这些mirna的进一步深入研究将有助于揭示其在巨噬细胞对病原体感染的作用所必需的不同生物学过程中的功能。

Identification of microRNAs from Atlantic salmon macrophages upon Aeromonas salmonicida infection
Computational approach was used in to identify potent macrophage specific miRNAs involved in basic biological process of Salmo salar. Analysis of 1119 ESTs from macrophages of Atlantic salmon (Salmo salar) infected with Aeromonas salmonicida revealed expression of 3 miRNAs. Phylogenetic analysis of both the pre-miRNA sequence revealed its evolutionarily conserved nature among various species. Identified targets of the predicted miRNAs revealed the role of miRNA in pathogenesis, stress response and allosteric exchange of histones. Further detailed studies of these miRNAs will help in revealing its function in different biological process necessary for the action of macrophages upon pathogen infection.
