GSM7061838: Sham Lung; Rattus norvegicus; RNA-Seq
Total RNA from the cells was isolated using the Trizol (Life Technologies, Carlsbad, CA, USA) according to the manufacturer's instructions, followed by a DNase I digestion for 30 minutes to remove genomic DNA Total RNA was treated with the RiboMinus kit (Life Technologies) to remove the ribosomal RNAs; RNAs were incubation with 16 units RNase R (Sigma–Aldrich, St. Louis, MO, USA) for 15 min at 37℃ to deplete linear and enrich circRNAs; The remaining RNAs were fragmented and reverse-transcribed using random primers and reverse transcriptase; Second strand cDNA synthesis was completed using DNA polymerase I and RNase H. Sixth, the Illumina series KAPA Library Preparation Kit (Kapa Biosystems) was used to perform end repair, dA-tailing, and adapter ligation; The dUTP-marked second strand was digested at 37 °C for 30 min using Uracil Specific Excision Reagent (USER) enzyme (New England Biolabs); The cDNA was enriched by PCR amplification to create the final cDNA libraries.
