近年来的研究表明,环状RNA (circular RNA, circRNAs)是一类丰富、稳定、普遍存在于动物体内的新型非编码RNA分子。从高通量转录组数据中全面检测环状rna是研究其生物发生和功能的关键一步。在这里,我们提出了一种新的基于交错剪切信号的算法CIRI,通过采用多种过滤策略,从转录组数据中无偏且准确地检测环状rna。通过将CIRI应用于ENCODE RNA-seq数据,我们首次鉴定并实验验证了内含子/基因间环状rna及其在人类转录组中的特异性片段的普遍存在。
Recent studies reveal that circular RNAs (circRNAs) are a novel class of abundant, stable and ubiquitous noncoding RNA molecules in animals. Comprehensive detection of circRNAs from high-throughput transcriptome data is an initial and crucial step to study their biogenesis and function. Here, we present a novel chiastic clipping signal-based algorithm, CIRI, to unbiasedly and accurately detect circRNAs from transcriptome data by employing multiple filtration strategies. By applying CIRI to ENCODE RNA-seq data, we for the first time identify and experimentally validate the prevalence of intronic/intergenic circRNAs as well as fragments specific to them in the human transcriptome.
