Immediate early proteins of herpes simplex virus transiently repress viral transcription before subsequent activation.

ABSTRACT: This study was undertaken to further clarify the roles of HSV-1 immediately early (IE) genes ICP4, ICP0, and ICP22 in early viral transcription. Precision nuclear Run On followed by deep Sequencing (PRO-Seq) was used to identify sites of Pol activity to high resolution on the genomes of HSV-1 viruses bearing mutations in a0, a4 or a22/US1, and corresponding viruses in which these loci were genetically restored. The results indicated that prior to initiating activation of transcription, IE genes first mediate transcriptional repression.

Transcriptomic analysis of early HSV-1 transcription in the absence of the immediate early protein, ICP4 [GRO-seq]

Project description:Herpes simplex virus 1 (HSV-1) transcription is tightly regulated in a temporal cascade, utilizing cellular RNA polymerase (Pol). We previously observed that infection with HSV-1 mutants lacking immediate early (IE) genes a0, a4 and a22 exhibited unusually high levels of aberrant transcription across the viral genome at just 1.5 hpi. The strongest effect occurred in the absence of a4, which is both an essential transcriptional activator and repressor. The goal of the current study was to define the mechanism of ICP4-mediated early transcriptional repression on the viral genome. Using the transcriptomic tools PRO-Cap, PRO-Seq, GRO-Seq and Nanopore direct RNA sequencing we found that initiation was elevated at viral promoters of all temporal classes in the absence of ICP4. Despite higher levels of initiation, transcription of non-IE genes was stalled within gene bodies and did not lead to production of mature mRNA. We therefore posit that HSV-1 retains additional ICP4-independent mechanisms to limit expression of viral genes that initiate prematurely. The data also indicated rapid release from promoter proximal pausing and progression along HSV IE genes and revealed termination as an important rate -limiting regulatory step. These findings highlight multiple mechanisms that HSV-1 employs to regulate early transcription and identify ICP4’s repressive role is to restrict initiation on non IE genes, thereby ensuring correct progression of the temporal cascade.

Identification of viral and host targets of miR-138 by PAR-CLIP analysis of herpes simplex virus 2 infected 293T cells

Project description:Like herpes simplex virus 1 (HSV-1) ICP0 mRNA, HSV-2 ICP0 mRNA is predicted to be targeted by a host neuron-specific microRNA, miR-138. This study was designed to confirm the interaction between HSV-2 ICP0 mRNA and miR-138, and to identify other potential viral and host targets of miR-138 during HSV-2 infection. We performed PAR-CLIP on HSV-2 infected 293T cells overexpressing miR-138 in comparisin to control 293T cells. The results confirmed ICP0 as miR-138's targets, and also identified some other potential viral and host targets of miR-138.

Identification of SLFN5 as an intrinsic inhibitor of viral transcription antagonized by the herpes simplex virus ubiquitin ligase ICP0

Project description:Intrinsic antiviral host factors are proteins that can confer cellular defense by limiting virus replication. Viruses hijack ubiquitin machinery to modify the cellular proteome to subvert these host defenses. The herpes simplex virus 1 (HSV-1) expresses ICP0, which functions as an E3 ubiquitin ligase required to promote infection. Cellular substrates of ICP0 have been discovered as host barriers to infection but the mechanisms for inhibition of viral gene expression are not fully understood. To identify new restriction factors antagonized by ICP0, we compared the proteomes associated with viral DNA (vDNA) during HSV-1 infection with wild-type (WT) virus and a mutant lacking functional ICP0 (ΔICP0). We identified the cellular protein Schlafen 5 (SLFN5) as a new ICP0 target that binds vDNA during HSV-1 ΔICP0 infection. We demonstrated that ICP0 mediates ubiquitination of SLFN5 which leads to its proteasomal degradation. In the absence of ICP0, we demonstrate SLFN5 binds vDNA to represses HSV-1 transcription by limiting accessibility of RNA polymerase II to viral promoters. These results identify SLFN5 as a new restriction factor that inhibits viral transcription and document the first viral countermeasure reported to overcome SLFN antiviral activity.

Effects of host miR-138 on herpes simplex virus 1 gene expression in Neuro-2a cells and their dependence of the binding sites on ICP0 mRNA

Project description:We previously showed that miR-138 can repress herpes simplex virus 1 (HSV-1) ICP0 expression by binding to ICP0 mRNA. However, in this study we found that miR-138 can also repress viral gene expression independent of ICP0. Therefore we conducted this RNAseq experiment to assess the effects of miR-138 on expression of each individual viral gene to search for other viral targets of miR-138

ICP22 of Herpes Simplex Virus 1 decreases RNA Polymerase Processivity

Project description:These data files consist of Illumina next seq 500 sequencing data from precision nuclear run-on and global nuclear run-on experiments conducted with human epithelial Hep2 cells that have been infected with human herpes simplex virus-1 (F) strain mutants. The results of these studies suggest that ICP22 is necessary for reducing Pol II processivity on the viral genome which results in its maintenance on the viral genome over the course of infection. While human reads continued to decrease over the time course of infection in the repair virus, this did not occur in the ICP22 deletion virus where over time the number of human reads increased over the time course of infection rather than decreasing. The effects of ICP22 deletion were separable from inhibiting HSV-1 DNA replication to the extent that ICP22 deletion resulted in a decrease in Pol levels only at 6 hpi and not at 3 hpi as was observed in the mutant
