摘要: 转运RNA(transfer RNA,tRNA)衍生的小RNAs(transfer RNA-derived small RNAs,tsRNAs)是来源于成熟tRNA或tRNA前体的一类新兴的非编码单链RNAs,主要包括tRNA衍生片段(tRNA-derived RNA fragments,tRFs)和tRNA半分子(tRNA halves,tiRNAs)两类。tsRNAs在多种肿瘤中存在差异性表达,并且影响肿瘤的增殖、侵袭或转移过程,尽管其背后的机制尚未完全阐明,但有成为肿瘤新的生物标志物及治疗靶点的潜力。本文对tsRNAs与常见肿瘤的关系进行综述,以期为肿瘤的诊断、治疗及预防提供新思路。Abstract: Transfer RNA-derived small RNAs (tsRNAs) are an emerging class of non-coding single-stranded RNA that are derived from mature transfer RNA (tRNA) or tRNA precursors. They primarily consist of tRNA-derived RNA fragments (tRFs) and tRNA halves (tiRNAs). Studies have confirmed that tsRNAs are differentially expressed in a variety of tumors and involved in tumor processes including proliferation, invasion, and metastasis. Although the underlying mechanisms have not been fully elucidated, tsRNAs have the potential to be new biomarkers and therapeutic targets for tumors. This review provides an overview of the relationship between tsRNAs and common tumors to provide new ideas for the diagnosis, treatment, and prevention of tumors.
