RNA was extracted using QIAGEN RNeasy kit. DNA after ChIP protocol was isolated using QIAGEN PCR purification kit. RNA-seq: Paramagnetic beads coupled with oligo d(T) are combined with total RNA to isolate poly(A)+ transcripts based on NEBNext® Poly(A) mRNA Magnetic Isolation Module manual. Prior to first strand synthesis, samples are randomly primed (5´ d(N6) 3´ [N=A,C,G,T]) and fragmented based on manufacturer's recommendation (NEBNext® Ultra™ II RNA Nondirectional Library Prep Kit for Illumina®). The first strand is synthesized with the Protoscript II Reverse Transcriptase with an longer extension period (40 minutes for 42◦C). All remaining steps for library construction were used according to the NEBNext® Ultra™ II RNA Nondirectional Library Prep Kit for Illumina®. Illumina 8-nt dual-indices were used. Samples were pooled and sequencing on a HiSeq with a read length configuration of 150 PE. ChIP-seq: ChIP-sequencing libraries were prepared using KAPA HyperPrep Kit (Kapa Biosystems) following manufacturer's recommendation. In brief, 500ng of input DNA sheared by Covaris LE220 ultrasonicator or 10 ng of immunoprecipitated DNA was end-repaired and 3'-dA tailed. Adapter was then ligated to the DNA, and ligated product was PCR amplified and cleaned up using SPRIselect Reagent (Beckman Coulter).
