Transfer RNA-derived small RNAs (tsRNAs) are a class of regulatory non-coding RNAs generated through enzymatic cleavage of precursor or mature tRNAs. In recent years, tsRNAs have garnered growing interest in nephrology due to their diverse biological functions and potential clinical significance. This review summarizes current research on the roles of tsRNAs in kidney diseases, including their involvement in gene expression regulation, signal transduction, apoptosis, and inflammation-related pathways. We further highlight their emerging mechanistic contributions in conditions such as acute kidney injury, chronic kidney disease, and glomerulonephritis. Finally, we discuss the prospects of tsRNAs as novel biomarkers for early diagnosis, prognosis assessment, and therapeutic targeting in renal disorders, aiming to offer new insights into kidney disease pathogenesis and management.

siRNA - Small Interfering RNAs
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...

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
