摘要
环状RNA(circular RNAs,circRNAs)是一类广泛存在于各种生物细胞中具有调控基因表达功能的非编码RNA,具有结构稳定和组织特异性表达等特征.有些circRNA分子富含微小RNA结合位点,可通过充当竞争性内源RNA的角色来发挥作用,如CDR1as对miR-7的海绵作用与肺癌、乳腺癌、胶质瘤及肌萎缩性脊髓侧索硬化等疾病发生相关.c ANRIL可通过影响多梳家族参与动脉粥样硬化的发生.大量circRNA的发现及其结构和功能的阐明不仅可以使我们更加深入地了解疾病的发生机制,而且为相关疾病的预防、诊断和治疗提供了新的方向.
Circular RNAs( circRNAs) represent a class of wide spread non-coding RNAs that regulate gene expression. They share a stable structure and tissue-specific expression and other features.Harboring microRNAs( miRNAs) competition sites,some circRNAs may act as competing endogenous RNAs. For example,CDR1 as sponging miR-7 is related with pathogenesis of lung cancer,breast cancer,glioma,and amyotrophic lateral sclerosis etc. c ANRIL affects atherosclerosis through Polycomb protein family members. With an overwhelming number of identified circRNAs in humans,in-depth study of the structure and function of circRNAs may not only push us to disclose mechanisms of some diseases,but also provide a new direction for the prevention,diagnosis and treatment of disorders.
