Abstract

MicroRNAs (miRNAs) perform a pivotal role in the regulation of gene expression across the animal kingdom. As negative regulators of gene expression, miRNAs have been shown to function in the genetic pathways that control many biological processes and have been implicated in roles in human disease. First identified as an aging-associated gene in C. elegans, miR-71, a miRNA, has a demonstrated capability of regulating processes in numerous different invertebrates, including platyhelminths, mollusks, and insects. In these organisms, miR-71 has been shown to affect a diverse range of pathways, including aging, development, and immune response. However, the exact mechanisms by which miR-71 regulates these pathways are not completely understood. In this paper, we review the identified functions of miR-71 across multiple organisms, including identified gene targets, pathways, and the conditions which affect regulatory action. Additionally, the degree of conservation of miR-71 in the evaluated organisms and the conservation of their predicted binding sites in target 3' UTRs was measured. These studies may provide an insight on the patterns, interactions, and conditions in which miR-71 is able to exert genotypic and phenotypic influence.

miR-71的保护和目标:一项系统综述和荟萃分析。
MicroRNAs (miRNAs)在整个动物王国的基因表达调控中发挥着关键作用。作为基因表达的负调控因子,mirna已被证明在控制许多生物过程的遗传途径中发挥作用,并在人类疾病中发挥作用。miR-71是一种miRNA,最初在秀丽隐杆线虫中被发现是一种与衰老相关的基因,它已被证明具有调节许多不同无脊椎动物(包括扁形蠕虫、软体动物和昆虫)过程的能力。在这些生物体中,miR-71已被证明影响多种途径,包括衰老、发育和免疫反应。然而,miR-71调控这些通路的确切机制尚不完全清楚。在本文中,我们回顾了miR-71在多种生物中的已识别功能,包括已识别的基因靶点、途径和影响调控作用的条件。此外,我们还测量了miR-71在被评估生物中的保守程度,以及它们在目标3' utr中预测的结合位点的保守程度。这些研究可能为miR-71能够发挥基因型和表型影响的模式、相互作用和条件提供见解。
