Since their discovery in the 1950s, transfer RNAs (tRNAs) have been best known for their role in helping the cell make proteins from messenger RNA templates. However, recent studies have led to a previously-unsuspected concept that tRNAs are not always the end product; namely, they further serve as a source of small RNAs. Now researchers from Thomas Jefferson University have discovered a new species of tRNA-derived … Continue reading Researchers discover new species of tRNA responsible for sex-biased cancer proliferation.
