Project description:For Samples 1-8 and 11-18: The innate immune sensor retinoic acid-inducible gene-I (RIG-I) detects double-stranded RNA derived from RNA viruses, and recent studies have demonstrated that RIG-I also plays a role in the antiviral response to DNA viruses. To identify the physiological RNA species that are recognized by RIG-I during HSV-1 infection, we purified the RNAs that co-immunoprecipitated with FLAG-tagged RIG-I in transfected human embryonic kidney (HEK) 293T cells that had been infected with a recombinant HSV-1 (hereafter referred to as HSV-1 mut) containing a mutation (K220A) in the viral serine/threonine protein kinase US3 that abolishes its catalytic activity, as the viral kinase is known to antagonize type-I IFN responses. As controls, RNA species bound to FLAG-RIG-I in uninfected cells and RNA bound to FLAG-GFP from both HSV-1 mut-infected and uninfected cells were also purified. RIG-I-bound RNA and total RNA extracted from uninfected and HSV-1 mut-infected cells were analyzed by RNAseq, and the resulting sequences were mapped to both the HSV-1F-strain and human genome (hg38). This analysis revealed that several human transcripts were highly enriched in the RIG-I-bound fraction from infected cells; in contrast, the enrichment of viral sequences was low. The cellular transcripts that were most abundant in the RIG-I fraction were predominantly non-coding RNAs from different subclasses, as well as some coding RNAs. For Samples 9 and 10: HSV-1 infection is known to induces changes in the transcriptional profile of the infected cell. To analyze global changes in RNA transcript levels in infected cells, total RNA was extracted from HEK 293T cells that were infected with wild-type (WT) HSV-1. For comparison, total RNA was extracted from HEK 293T cells that remained uninfected. Next, RNAseq analysis was performed. The resulting sequences were mapped to the human genome, and gene inductions were calculated and normalized to uninfected samples to determine changes in gene expression upon infection.

Project description:This is a part of the study that shows that a host microRNA, miR-138, represses herpes simplex virus 1 (HSV-1) gene expression through both viral and host targets. These PAR-CLIP analyses identified viral and host targets of miR-138 in Neuro-2a (mouse neuroblastoma) and 293T (human embryonic kidney) cells. We constructed two cell lines derived from Neuro-2a cells, one overexpressing miR-138 (N2A138) and one antagonizing miR-138 (N2Aanti138). We also constructed two cell lines derived from 293T cells, one overexpressing miR-138 (293T138) and one control cells (293Tcontrol). Uninfected N2A138 and N2Aanti138 were compared by PAR-CLIP for host targets in Neuro-2A cells. 293T138 and 293Tcontrol cells infected for 4 and 8 hours were compared by PAR-CLIP for HSV-1 targets in 293T cells. 293T138 and 293Tcontrol cells infected for 4 hours were also compared for host targets in 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.

Project description:BONCAT-MS analysis was performed against several HSV-1 infected and uninfected Hela cells.
PPI analysis of HSV-1 protein was performed against Flag-tagged HSV-1 protein expressed 293T cells.

Project description:Herpes simplex virus type-1 (HSV-1) is wide-spread dsDNA virus that establishes life-long latency and causes diverse severity of symptoms. In this study, HEK 293T cells with low Toll-like receptor (TLR) and Stimulator of interferon genes protein (STING) expression was infected with HSV-1 and subjected to quantitative proteomic analysis. By using a subcellular fractionation strategy and high-performance mass spectrometry, a total of 5,982 host proteins were quantified, of which 484 proteins were differentially regulated. Bioinformatics analysis indicated that multiple signaling pathways were involved in HSV-1 infection.

Project description:The goal of this study was to determine how RNA poymerase II (Pol II) occupancy changed in response to herpes simplex virus-1 (HSV-1) infection using ChIP-seq of Pol II. ChIP assays were performed 4 hours after cells were infected (or mock infected) with HSV-1. Because host cell Pol II transcribes the HSV-1 genome, the ChIP-seq data also reveal polymerase occupancy on the viral genome.
