title: Negative control
design: Total RNA was isolated from cells/tissues using the Magzol Reagent (Magen, China)according to the manufacturers protocol, The quantity and integrity of RNA yield was assessed by using the K5500(BeijingKaiao, China) and the Agilent 2200 TapeStation (Agilent Technologies, USA) separately. Briefly, the mRNA was enriched by oligodT according to instructions of NEBNext Poly(A) mRNA Magnetic Isolation Module (NEB,USA). And then fragmented to approximately 200bp. Subsequently, theRNA fragmentswere subjected to first strand and second strand cDNA synthesis following by adaptor ligation and enrichment with a low-cycleaccording to instructions ofNEBNext Ultra RNA Library Prep Kit for Illumina. The purified library products were evaluated using the Agilent 2200 TapeStation and Qubit(Thermo Fisher Scientific, USA). The libraries were sequenced by Illumina (Illumina, USA) with paired-end 154bp at Ribobio Co. Ltd (Ribobio, China).
