microRNA(miRNAs)是一类调控靶基因转录后表达的短RNA分子。这种调节可能采取稳定的翻译抑制或靶转录物的降解的形式,尽管控制miRNA介导的调节的结果的机制在很大程度上仍然未知。虽然越来越清楚的是,miRNA是基因调控网络的核心组成部分,阐明这些网络中每个miRNA的精确作用将需要一个准确的方法来识别靶基因和评估miRNA对单个靶点的影响。目前有许多用于预测目标的计算方法。这些方法在其重点、准确性和研究人员的易用性方面差异很大。这篇评论将集中在动物中可用的计算方法的比较,重点是通过实验分析microRNA的方法:目标复合物。
MicroRNAs (miRNAs) are short RNA molecules that regulate the post-transcriptional expression of their target genes. This regulation may take the form of stable translational repression or degradation of the target transcript, although the mechanisms governing the outcome of miRNA-mediated regulation remain largely unknown. While it is becoming clear that miRNAs are core components of gene regulatory networks, elucidating precise roles for each miRNA within these networks will require an accurate means of identifying target genes and assessing the impact of miRNAs on individual targets. Numerous computational methods for predicting targets are currently available. These methods vary widely in their emphasis, accuracy, and ease of use for researchers. This review will focus on a comparison of the available computational methods in animals, with an emphasis on approaches that are informed by experimental analysis of microRNA:target complexes.
