The Downregulation of GFI1 by the EZH2-NDY1/KDM2B-JARID2 Axis and by Human Cytomegalovirus (HCMV) Associated Factors Allows the Activation of the HCMV Major IE Promoter and the Transition to Productive Infection

English version České info

Human cytomegalovirus (HCMV) is a significant pathogen that belongs to the herpesvirus family. Here we show that the histone H3K27 methyltransferase EZH2 and its regulators JARID2 and NDY1/KDM2B are required for the establishment of productive infection. Mechanistically, the EZH2-NDY1/KDM2B-JARID2 axis downregulates GFI1, a repressor of the HCMV major-immediate-early promoter (MIEP) and inhibition of this axis upregulates GFI1 and interferes with the activation of the MIEP and HCMV infection. GFI1 is rapidly downregulated during infection in both wild-type and EZH2, NDY1/KDM2B, JARID2 knockdown cells. However, since the starting levels of GFI1 in the latter are significantly higher, they remain high despite the virus-induced GFI1 downregulation, preventing the infection. Following the downregulation of GFI1 immediately after virus entry, HCMV initiates an EZH2-NDY1/KDM2B-JARID2-JMJD3-dependent program to maintain the low expression of GFI1 throughout the infection cycle. The knockdown of EZH2 also modulates the accumulation of histone H3K27me3 and H3K4me3 in the immediate-early region of HCMV, and by doing so, it may contribute directly to the MIEP repression induced by the knockdown of EZH2. These data show that HCMV uses multiple mechanisms to allow the activation of the HCMV MIEP and to prevent cellular mechanisms from blocking the HCMV replication program.
