MicroRNAs (miRNAs)在调控基因表达中发挥着重要作用。由于mirna通常在进化上是保守的,它们的前体可以折叠成茎环发夹,因此已经预测了许多mirna。然而,实验证实是困难的,因为miRNA的表达往往特定于特定的组织和发育阶段。对29个人和230个小鼠longSAGE文库进行分析,发现22个已知和10个预测的哺乳动物mirna表达。大多数在胚胎组织中检测到。在人类胚胎干细胞中检测到的四个SAGE标签特异性匹配已知在胚胎干细胞中表达的四个人类mirna (mir-302a, b, c&d)簇。LongSAGE数据还表明存在人类和大鼠mir-493的小鼠同源物。观察到一些孤儿长sage标签独特地匹配miRNA前体,提供了一些已知和预测的miRNA表达的信息。
MicroRNAs (miRNAs) have been shown to play important roles in regulating gene expression. Since miRNAs are often evolutionarily conserved and their precursors can be folded into stem-loop hairpins, many miRNAs have been predicted. Yet experimental confirmation is difficult since miRNA expression is often specific to particular tissues and developmental stages. Analysis of 29 human and 230 mouse longSAGE libraries revealed the expression of 22 known and 10 predicted mammalian miRNAs. Most were detected in embryonic tissues. Four SAGE tags detected in human embryonic stem cells specifically match a cluster of four human miRNAs (mir-302a, b, c&d) known to be expressed in embryonic stem cells. LongSAGE data also suggest the existence of a mouse homolog of human and rat mir-493. The observation that some orphan longSAGE tags uniquely match miRNA precursors provides information about the expression of some known and predicted miRNAs.
