DNA virus infections shape transposable element activity in vitro and in vivo (HCMV,KSHV,DUX4) - Cut&Run of H3K9me3 and Phospho-KAP-1
We show strong activation of TEs in the context of DNA virus infection and investigate the molecular mechanisms of how TEs are induced. We demonstrate that herpesvirus infection leads to a robust expression of the MLT and THE1-class of LTR containing retrotransposons as well as a subset of long-interspersed nuclear elements-1 (LINEs), Alu-elements and some HERVs. Mechanistically we demonstrate that this TEs upregulation is induced by two pathways that act synergistically: de-repression of KAP1/TRIM28 mediated by phosphorylation and expression of the pioneer factor double-homeobox 4 (DUX4). Here, we show changes in H3K9me3 and Phospho-KAP-1 (Ser473) during two HSV-1 infection timepoints (6h and 14h).
