RNA was harvested using BioRad total RNA extraction kit with DNaseI treatment. For ChIP cells were fixed with 0.8% formaldehyde for 8 min at RT and DNA was processed and sonicated according to the protocol from Covaris using Covaris S220 sonicator for 4-5 min. RNA libraries for pair-end read sequencing were prepared by using standard Illumina protocols. ChIP libraries were prepared by using ThruPLEX DNA kit (Rubicon).
