Pseudogenes have been shown to acquire unique regulatory roles from more and more organisms. We report the observation of a cluster of siRNAs derived from pseudogenes of African Trypanosoma brucei using high through-put analysis. We show that these pseudogene-derived siRNAs suppress gene expression through RNA interference. The discovery that siRNAs may originate from pseudogenes and regulate gene expression in a unicellular eukaryote provides insights into the functional roles of pseudogenes and into the origin of noncoding small RNAs.
越来越多的研究表明,假基因可以获得独特的调控作用。我们报道了使用高通量分析观察到来自非洲布氏锥虫假基因的一组 siRNA。我们表明,这些假基因衍生的 siRNA 通过 RNA 干扰抑制基因表达。siRNA 可能起源于假基因并在单细胞真核生物中调节基因表达的发现,为假基因的功能作用以及非编码小 RNA 的起源提供了新的见解。
