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: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: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. We did not find other confirmed viral targets of miR-138. Therefore we conducted these RNAseq experiments (in combination with PAR-CLIP experiments whose results are uploaded separately) to identify host targets of miR-138 in two cell lines to explain the ICP0-independent effects on HSV-1 gene expression.

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
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:We show that Herpes simplex virus 1 (HSV-1) induces the expression of about 1000 antisense transcripts from the human host cell genome.
Project description:The goal of the study was to determine whether low dose HDACi sensitizes human malignant meningioma cells to the cytotoxic capacity of oncolytic herpes simplex virus G47delta. RNA sequencing was used to examine transcriptomic changes mediated by HDACi preexposure before oncolytic virus infection.
Project description:This is a part of the study that shows that a host gene,ONECUT2 (OC2), promote herpes simplex virus 1 (HSV-1) transcription. These RNA-seq analyses viral genes transcription in Neuro-2a cells. Neuro-2a cells were transfected with pOC2△HOX2 and pcDNA plasmids for 42 hours then infected with herpes simple virus1 for 5 hours.
