RNA was extracted using QIAGEN RNeasy kit. DNA after ChIP protocol was isolated using QIAGEN PCR purification kit. ChIP-sequencing libraries were prepared using the KAPA HTP Library Preparation Kit complemented with NEXTflex DNA Barcodes from Bioo Scientific. 10 ng of DNA was used as starting material for input and ip samples. Libraries were amplified using 13 cycles on the thermocycler. Post amplification libraries were size selected at 250- 450bp in length using Agencourt AMPure XP beads from Beckman Coulter. Libraries were validated using the Agilent High Sensitivity DNA Kit. RNA-sequencing libraries were prepared using the Illumina TruSeq Stranded Total RNA Preparation Kit with Ribo-Depletion. Input RNA quality was validated using the Agilent RNA 6000 Nano Kit. 200ng-1 µg of total RNA was used as starting material. Libraries were validated using the Agilent DNA 1000 Kit. For Bisulfite-seq, genomic DNA was quantified with a Qubit 3.0 instrument. ~250 ng of genomic DNA was then digested with the restriction endonuclease MspI (New England BioLabs). Resulting fragments underwent size selection for fragments ~100-250-bp in length using SPRI beads (MagBio Genomics) and subsequent bisulfite conversion using the EZ DNA Methylation-Lightning Kit (Zymo Research) per the manufacturer's protocol. Bisulfite conversion efficiency averaged > 99% as estimated by the measured percent of unmethylated CpGs in λ-bacteriophage DNA (New England BioLabs N3013S) added at a 1:200 ratio to each sample. Libraries for Illumina-based sequencing were prepared with the Pico Methyl-Seq Library Prep Kit (Zymo Research) using Illumina TruSeq DNA methylation barcodes. Libraries were run on a High Sensitivity chip using an Agilent TapeStation 4200 to assess size distribution and overall quality of the amplified library. Fluorometric quantitation and TapeStation size distribution estimates permitted equimolar pooling, and 6 pooled libraries per run were sequenced on an Illumina NextSeq 500 instrument using the NextSeq 500/550 V2 High Output reagent kit (1 x 75 cycles).
