ABSTRACT
Transfer RNA-derived small RNAs (tsRNAs), a recently identified subclass of small non-coding RNAs (sncRNAs), emerge through the cleavage of mature transfer RNA (tRNA) or tRNA precursors mediated by specific enzymes. The tumor necrosis factor (TNF) protein, a signaling molecule produced by activated macrophages, plays a pivotal role in systemic inflammation. Its multifaceted functions include the capacity to eliminate or hinder tumor cells, enhance the phagocytic capabilities of neutrophils, confer resistance against infections, induce fever, and prompt the production of acute phase proteins. Notably, four TNF-related tsRNAs have been conclusively linked to distinct diseases. Examples include 5'tiRNA-Gly in skeletal muscle injury, tsRNA-21109 in systemic lupus erythematosus (SLE), tRF-Leu-AAG-001 in endometriosis (EMs), and tsRNA-04002 in intervertebral disk degeneration (IDD). These tsRNAs exhibit the ability to suppress the expression of TNF-α. Additionally, KEGG analysis has identified seven tsRNAs potentially involved in modulating the TNF pathway, exerting their influence across a spectrum of non-cancerous diseases. Noteworthy instances include aberrant tiRNA-Ser-TGA-001 and tRF-Val-AAC-034 in intrauterine growth restriction (IUGR), irregular tRF-Ala-AGC-052 and tRF-Ala-TGC-027 in obesity, and deviant tiRNA-His-GTG-001, tRF-Ser-GCT-113, and tRF-Gln-TTG-035 in irritable bowel syndrome with diarrhea (IBS-D). This comprehensive review explores the biological functions and mechanisms of tsRNAs associated with the TNF signaling pathway in both cancer and other diseases, offering novel insights for future translational medical research.
