The three-dimensional structure of Epstein-Barr virus genome varies by latency type and is regulated by PARP1 enzymatic activity [RNA-Seq]
PARP does have an essential role in the regulation of global EBV episome chromatin structure. We have functionally characterized the effect of PARP enzymatic inhibition on total episomal structure and we mapped intragenomic contact changes after PARP inhibition to global binding of the chromatin looping factors CTCF and cohesin across the EBV genome. The altered expression profile after the structural rearrangement induced by PARP inhibition supports the model where PARP1 helps maintain EBV latency programs. Overall design: Two biological replicates of both LCL and Mutu control cell and olaparib [2.5 uM] treated cells. For RNAseq total RNA was extracted and depleted of the ribosomal RNA component using RiboZero (Epicentre).
