Abstract:
This article explores the important functions of transfer RNA and - transfer RNA derived small RNAs (tsRNAs) in cellular processes and disease pathogenesis, with a particular emphasis on their involvement in cerebrovascular disorders. It discusses the biogenesis and structure of tsRNAs, including types such as tRNA halves and tRNA-derived fragments, and their functional significance in gene regulation, stress response, and cell signaling pathways. The importance of tsRNAs in neurodegenerative diseases, cancer, and cardiovascular diseases has already been highlighted, while their role in cerebrovascular diseases is in early phase of exploration. This paper presents the latest advancements in the field of tsRNAs in cerebrovascular conditions, such as ischemic stroke, intracerebral hemorrhage, and moyamoya disease. Furthermore, revealing the aptitude of tsRNAs as biomarkers for the prediction of cerebrovascular diseases and as targets for therapeutic intervention. It provides insights into the role of tsRNAs in these conditions and proposes directions for future research.

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...
Transfer RNA Synthesis
Each of these chemical modifications is carried by a specific enzyme, post-transcription. All of these enzymes have unique base and site-specificity. Methylation, the most common chemical modification, is carried by at least nine different enzymes, with...
Nucleic Acids
DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes,...
RNA Interference
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...
