Advances in research on the mechanism of tsRNA action in tumours.

tsRNA is a class of non-coding RNAs derived from mature or precursor tRNAs. In recent years, more and more studies have explored the correlation between tsRNAs and tumours. tsRNAs can affect the biological behaviours of tumour cells such as proliferation, apoptosis and metastasis by regulating gene expression, protein translation or post-transcriptional regulation. In this paper, we systematically review the production, biological function and research progress of tsRNA in tumour and discuss its prospects as biomarkers and therapeutic targets.
