library_construction_protocol: Total RNA was isolated by using TRIzol reagent (Invitrogen), and Bru-labeled RNA was isolated from the total RNA by incubation with anti-BrdU antibodies (BD Biosciences) conjugated to magnetic beads (Dynabeads, Goat anti-Mouse IgG; Invitrogen) under gentle agitation at room temperature for 1 h. For more detail, see Paulsen et. al 2013 Bru-labeled RNA was mixed with first strand buffer and random primers and fragmented by heating at 85 ̊C for 10 minutes. The first strand cDNA was then synthesized, in the presence of Actinomycin D, to result in strand specific reads. After purifying the first strand cDNA using AMPure RNAclean beads (Beckman Coulter), the second strand cDNA was synthesized. The resulting cDNA was purified with AMPure XP beads, after which the Illumina TruSeq RNA Sample Prep Kit was used to repair the cDNA ends, adenylate and ligate adaptors to the cDNA. The samples were then run on a 3% agarose gel and size-selected by excising gel slices in the 300bp region. These gel slices were purified using the QIAEX II Gel Extraction Kit (Qiagen) and then the Illumina TruSeq Kit PCR reagents were used to enrich the DNA fragments. After a final purification using AMPure XP beads, the quality and concentration of the DNA libraries were determined using an Agilent Bioanalyzer.
