摘要:
环状核糖核酸(circular ribonucleic acid, circular RNA或circRNA)是一类无 5′ 帽子结构及 3′ poly A 尾,以共价键连接形成闭合环形结构的非编码RNA分子, 通过转录后调控的方式参与动植物细胞的众多代谢途径. 莱茵衣藻(Chlamydomonas reinhardtii, C. reinhardtii)是一种重要的真核单细胞模式微藻, 为探究其是否存在环状 RNA, 本研究通过RNA-Seq高通量测序分析正常与缺硫培养的C. reinhardtii RNA组学数据, 首次预测获得218条环状 RNA序列, 通过对比缺硫处理前后莱茵衣藻环状 RNA 序列, 获得8条差异表达的环状 RNA序列(其中,5条为表达上调、3条为表达下调). 本研究首次对单细胞真核微藻莱茵衣藻进行环状 RNA的生物信息学预测, 确认莱茵衣藻环状 RNA响应缺硫胁迫, 为下一步揭示莱茵衣藻环状 RNA参与响应莱茵衣藻缺硫的作用机制奠定基础.
Abstract:
Circular ribonucleic acid (circular RNA or circRNA) is a class of non-coding RNA without 5′ cap-structure and 3′ poly A tail, connected by covalent bonds to form a closed circular structure, and involved in numerous metabolic pathways in animal and plant cells through post-transcriptional regulations. Chlamydomonas reinhardtii (C. reinhardtii) is an important eukaryotic single-cell microalga. In this study, 218 sequences associated with circRNA were predicted for the first time in C. reinhardtii. By comparing the sequences of circRNA from sulfur-replete and sulfur-deprived C. reinhardtii, 8 differentially expressed circRNA sequences were obtained (5 of them were up-regulated and 3 were down-regulated). This is the first report on a circRNA bioinformatics prediction of C. reinhardtii, confirming that the circRNA of C. reinhardtii responds to sulfur deprived stress.
