library_construction_protocol: Total RNA was extracted from frozen tissues using Trizol LS (Life Technologies, Carlsbad, CA, USA) according to the manufacturer's instructions. 1-2 ug of total RNA was used for the construction of sequencing libraries. Sequencing libraries are size-selected for the RNAbiotypes to be sequenced using an automated gel cutter. The libraries are qualified and absolutely quantified using Agilent BioAnalyzer 2100. For standard small RNA sequencing on Illumina NextSeq instrument, the sequencing type is 50bp single- read. tRF&tiRNA-seq
