Modification-aware small RNA sequencing generated single-end 50-nucleotide reads. The submission includes nine raw FASTQ files and a complete vendor-annotated tRF/tiRNA feature-by-sample quantitative matrix containing raw counts and CPM values.2026/09/02GSE343860GSM9963790GSM9963792GSM9963794GSM9963796GSM9963798GSM9963800GSM9963803GSM9963802GSM996380521697343860Homo sapiens
