Transfer- or ‘transmission’-RNA fragments? The roles of tsRNAs in the reproductive system

Molecular Human Reproduction, 2021
ABSTRACTTransfer-RNAs (tRNAs) help ribosomes decode mRNAs and synthesize proteins; however, tRNA fragments produced under certain conditions, known as tRNA-derived small RNAs (tsRNAs), have been found to play important roles in pathophysiological processes. In the reproductive system, tsRNAs are abundant in gametes and embryos and at the maternal–fetal

The RNA Methyltransferase Dnmt2 Is Required for Efficient Dicer-2-Dependent siRNA Pathway Activity in Drosophila

Cell Reports, 2013
Transfer RNA (tRNA) fragmentation in response to stress conditions has been described in many organisms. tRNA fragments have been found in association with small interfering RNA (siRNA) components, but the biological role of these interactions remains ...

Host tRNA-Derived RNAs Target the 3′Untranslated Region of SARS-CoV-2

Pathogens, 2022
The COVID-19 pandemic revealed a need for new understanding of the mechanisms regulating host–pathogen interactions during viral infection. Transfer RNA-derived RNAs (tDRs), previously called transfer RNA fragments (tRFs), have recently emerged as ...

Identification of transfer RNA-derived fragments and their potential roles in aortic dissection

Genomics, 2021
Emerging evidence suggests that majority of the transfer RNA (tRNA)-derived small RNA, including tRNA-derived fragments (tRFs) and tRNA halves (tiRNAs), play a significant role in the molecular mechanisms underlying some human diseases. However, expression of tRFs/tiRNAs and their potential roles in aortic dissection (AD) remain unclear.

Small RNA populations revealed by blocking rRNA fragments in Drosophila melanogaster reproductive tissues. [PDF]

PLoS ONE, 2018
RNA interference (RNAi) is a complex and highly conserved regulatory mechanism mediated via small RNAs (sRNAs). Recent technical advances in high throughput sequencing have enabled an increasingly detailed analysis of sRNA abundances and profiles in ...

Emerging connections between small RNAs and phytohormones [PDF]

, 2020
Small RNAs (sRNAs), mainly including miRNAs and siRNAs, are ubiquitous in eukaryotes. sRNAs mostly negatively regulate gene expression via (post-)transcriptional gene silencing through DNA methylation, mRNA cleavage, or translation inhibition.

The biogenesis pathway of tRNA-derived piRNAs in Bombyx germ cells. [PDF]

, 2017
Transfer RNAs (tRNAs) function in translational machinery and further serves as a source of short non-coding RNAs (ncRNAs). tRNA-derived ncRNAs show differential expression profiles and play roles in many biological processes beyond translation ...

Non-coding RNAs and epithelial mesenchymal transition in cancer: molecular mechanisms and clinical implications

Journal of Experimental & Clinical Cancer Research, 2022
Epithelial-mesenchymal transition (EMT) is a fundamental process for embryonic development during which epithelial cells acquire mesenchymal characteristics, and the underlying mechanisms confer malignant features to carcinoma cells such as dissemination

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

FEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...
