    摘要:

    环状RNA (circular RNA,circRNA)是一种单链环状闭合RNA分子，由线性RNA通过反向剪接形成，具有稳定、高度保守、组织特异性等特点。circRNA能够通过形成竞争性内源性RNA、结合蛋白等多种方式参与机体的生理、病理过程。最近发现，circRNA分子可以通过翻译形成多肽或蛋白参与癌症的发生和发展。circRNA是人类癌症中有前途的诊断和预后标志物，也是癌症治疗的潜在药物靶点。本文重点介绍了circRNAs编码的多肽和蛋白质在多种癌症中的相关研究进展。这些多肽和蛋白质分别依赖内部核糖体进入位点和m6A两种不同的机制进行翻译。我们还总结了circRNA编码的多肽和蛋白质在各种癌症的诊断、治疗、预后和机制研究中的潜在用途。

    Abstract:

    Circular RNA (circRNA) is a single-stranded circular closed RNA molecule formed from linear RNA through reverse splicing. circRNAs are stable, highly conserved, and tissue-specific. circRNAs can regulate physiological and pathological processes through various mechanisms such as formation of competing endogenous RNA and interaction with binding proteins. It has been recently revealed that circRNAs can be translated into peptides and proteins to participate in the initiation and development of cancer. circRNAs are promising diagnostic and prognostic markers for human cancers as well as potential drug targets for cancer therapy. This review summarized the research progresses related to circRNA-encoded peptides and proteins in a variety of cancers. These peptides and proteins are translated through two different mechanisms that depend on internal ribosome entry site and m6A, respectively. We also summarized the potential use of circRNA-encoded peptides and proteins in the diagnosis, treatment, prognosis and mechanistic studies of various cancers.
