total RNA 4sU-RNA was used for library preparation with NEBNext rRNA Depletion Kit (Human/Mouse/Rat) and NEBNext Ultra II Directional RNA Library Prep kit. The libraries were amplified with 10-14 PCR cycles depending on the input RNA. The concentration and size distribution of the libraries were determined on a Fragment Analyzer using the NGS Fragment High Sensitivity Analysis Kit (1-6,000 bp; Agilent Technologies). The libraries were sequenced on the NextSeq500 Illumina platform for 75 cycles. Base calling was performed using Illumina's BaseSpace platform
