tRNA-derived small noncoding RNAs: Roles in brain aging and neurodegenerative disorders.

Transfer ribonucleic acid-derived small ribonucleic acids (tsRNAs) are an emerging class of regulatory noncoding RNAs produced through the precise cleavage of mature or precursor tRNAs (pre-tRNAs). Once considered degradation byproducts, tsRNAs are n…
