The paper examines dynamic changes in tRNA modifications and abundance during T-cell activation, finding reduced wybutosine and ms2t6A modifications that may increase ribosomal frameshifting and facilitate HIV infection.

The paper identifies tRNA subsets essential for cellular proliferation or arrest by CRISPR-based editing and functional analysis in human cell lines.

The paper systematically detects amino acid substitutions in proteomes using mass spectrometry data and reveals that translation errors are primarily caused by codon-anticodon mispairing, with patterns influenced by ribosome velocity and evolutionary constraints.
