tRFs and tiRNAs, generated through precise biogenesis processes from tRNA, perform many biological functions as small noncoding RNAs and are associated with many diseases and conditions (Fig.1) . They are known to act as microRNAs in RNA interference; bind protein factors to regulate target mRNA stability; interact with cytochrome c to modulate apoptosis; alter embryonic transcriptional cascades as paternal epigenetic factor in intergenerational inheritance of metabolic disorders; and assemble stress granules in response to stress conditions.
The composition and abundance of tRFs&tiRNAs are highly dependent on the cell type and disease condition, making them excellent biomolecules for biomarkers [1]. For example, the ratio of tRFs&tiRNAs is a good indicator of cancer progression-free survival and a candidate prognostic marker [2]. Also tRNA and tRF&tiRNA populations are highly enriched in biofluids, much more so than microRNAs [3-4].
