数以百计的tRNA基因和假基因由人类基因组编码。TRNAs是细胞中第二丰富的RNA类型。深度测序技术的进步揭示了功能tRNA衍生的RNA片段(TRFs)的大量表达。它们要么是由前体(前)tRNA产生的,要么是由成熟tRNA产生的。它们被发现在不同的病理条件下发挥着关键的调节作用。在这里,我们简要地总结了TRFs在人类不同疾病的病理生理学中所起的调节作用的发现和最新进展。对RNA疗法潜力的洞察导致了非编码RNA领域的广泛研究进展。这篇综述提供了关于tRNA衍生的RNA片段的洞察力,并总结了它们在各种人类疾病的病理生理学中的各种功能意义。
Hundreds of tRNA genes and pseudogenes are encoded by the human genome. tRNAs are the second most abundant type of RNA in the cell. Advancement in deep-sequencing technologies have revealed the presence of abundant expression of functional tRNA-derived RNA fragments (tRFs). They are either generated from precursor (pre-)tRNA or mature tRNA. They have been found to play crucial regulatory roles during different pathological conditions. Herein, we briefly summarize the discovery and recent advances in deciphering the regulatory role played by tRFs in the pathophysiology of different human diseases. Insights into the potential of RNA therapeutics have led to the extensive research progress in the arena of non-coding RNAs. This review provides insight about the tRNA-derived RNA fragments and summarizes their various functional implications in the pathophysiology of various human diseases.
