Summary
Transfer RNA-derived small RNAs (tsRNAs) are key regulators of cellular processes. This review details their altered expression in liver diseases like hepatitis, MASLD, and HCC, highlighting their biomarker and therapeutic potential.
Area of Science:
- Molecular Biology
- Genetics
- Biochemistry
Background:
- Transfer RNA-derived small RNAs (tsRNAs) are emerging small non-coding RNAs.
- tsRNAs are generated from mature tRNAs or precursors via enzymatic cleavage.
- They regulate critical cellular functions including protein synthesis and gene expression.
Purpose of the Study:
- To provide a comprehensive overview of tsRNA functional characteristics.
- To highlight expression changes of 24 specific tsRNAs in liver diseases.
- To explore the role of tsRNAs in various liver pathologies and their potential as biomarkers and therapeutic targets.
Main Methods:
- Literature review of current research on tsRNAs in liver diseases.
- Analysis of tsRNA expression profiles in conditions such as hepatitis B/C, alcoholic liver disease, MASLD/NAFLD, and HCC.
- Examination of regulatory mechanisms and biological roles of tsRNAs.
Main Results:

Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

26.5K
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

21.8K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

Translational regulation in prokaryotes ensures efficient protein synthesis by controlling ribosome access to mRNA. This regulation is mediated by secondary RNA structures, including translational riboswitches, RNA thermometers, and small RNAs (sRNAs), which respond to intracellular and environmental signals to modulate gene expression.Translational RiboswitchesRiboswitches in the leader region of mRNAs can regulate translation by altering the accessibility of the Shine-Dalgarno (SD) sequence,...
