Computational Approaches to tRNA-Derived Small RNAs
tRNA-derived small RNAs (tDRs) are a group of small, non-coding RNAs derived from transfer RNAs (tRNAs). They can be classified as tRNA halves and tRNA-derived small RNA fragments (tRFs). Accumulating experimental evidence suggests their functional roles in cells and in various biological processes. Advances in next-generation sequencing (NGS) techniques allow a large amount of small RNA deep-s...
متن کاملHints of tRNA-Derived Small RNAs Role in RNA Silencing Mechanisms
With the advent of new and improved high-throughput sequencing technologies in the last few years, a growing number of novel classes of small RNA, other than miRNAs or siRNA, has emerged, which appear as new actors in gene expression regulation. tRNA-derived small RNAs represent one of these novel members that are, surprisingly, among the most conserved class of small RNAs throughout evolution....
متن کاملtRNA-derived small RNAs target transposable element transcripts
tRNA-derived RNA fragments (tRFs) are 18-26 nucleotide small RNAs that are not random degradation products, but are rather specifically cleaved from mature tRNA transcripts. Abundant in stressed or viral-infected cells, the function and potential targets of tRFs are not known. We identified that in the unstressed wild-type male gamete containing pollen of flowering plants, and analogous reprodu...
متن کاملHigh throughput sequencing reveals a plethora of small RNAs including tRNA derived fragments in Haloferax volcanii
To define the complete sRNA population of the halophilic archaeon Haloferax volcanii, we employed high throughput sequencing. cDNAs were generated from RNA ranging in size from 17 to 500 nucleotides isolated from cells grown at three different conditions to exponential and stationary phase, respectively. Altogether, 145 intergenic and 45 antisense sRNAs were identified. Comparison of the expres...
