Project description:The in vitro effect of infection with different strains of Toxoplasma gondii was tested 24 hours after infection of Human Foreskin Fibroblasts (HFF) The strains tested include RH, VEG, and transgenic strains of RH overexpressing ROP38 or ROP21

Project description:We performed paired-end PRO-Seq and/or PRO-Cap on human foreskin fibroblasts (HFF) infected with human cytomegalovirus (HCMV) for 4 h (strain TB40/E) or 96 h (strain Towne varS). Each sample has matched uninfected controls. Towne experiments were also performed with adapters containing 4 nt of random sequence flanking both sides (8 total bases of randomness) to enable deduplication. Reads were first mapped to the human genome (hg38) (files available on GEO). Unmapped reads were then mapped to HCMV (Genbank FJ616285.1) (track hub available at https://github.com/P-TEFb/trackHub_HCMV).

Project description:To characterize transcription throughout the HCMV infection, paired-end PRO-Seq was performed on human foreskin fibroblasts (HFF) infected with human cytomegalovirus (HCMV) for 4 h, 12 h, 24 h, 48 h, and 72 h using the TB40/e strain. Cells were treated with 1µM flavopiridol 1 hour prior to isolation. Additionally, PRO-Cap was performed on untreated HFFs after 72 h of infection. Each experiment was performed with adapters containing 8 nt of random sequence flanking both ends (16 total bases of randomness) to enable deduplication.

Project description:Cytomegalovirus (CMV) strains with different in vivo and in vitro characteristics may induce different patterns of cellular gene expression. CMV strain fhCMV-H, which spreads rapidly through cell culture, was isolated from a hematopoetic stem cell transplant patient who died of CMV-mediated marrow failure. In contrast fhCMV-T was isolated from a patient who survived CMV complications and does not spread rapidly in vitro. Fibroblasts were infected with both strains, which had been engineered to express GFP upon cellular infection, and the cellular gene expression profile was compared to that of noninfected controls at 24h. The gene expression profile of HFF exposed to UV-inactivated virus from the 2 strains was also tested, to differentiate the effects of the initial engagement with virus coat proteins such as glycoprotein B and gene modulation by active virus.

Project description:Human cytomegalovirus (HCMV) is a common cause of morbidity and mortality in immunocompromised and immunosuppressed individuals. During infection, HCMV is known to employ host transcription factors to facilitate viral gene expression. To further understand the previously observed delayed viral replication and protein expression in p53 knockout cells, we conducted microarray analyses on p53+/+ and p53-/- immortalized fibroblast cell lines. At 12 hpi, applying the significance criteria defined above, no genes showed a significant difference in any of the comparisons. At 24 hpi, we found 19 genes to be significantly different in the THF versus p53-/- comparison and 14 genes to be significantly different in the HFF versus p53-/- comparison. Eleven genes were shared between HFF and THF cells when compared to p53-/- cells (UL30, UL54, UL63, UL65, UL69, UL75, UL110, UL122, IRL4, IRS1, TRS1, shown in bold in Table 1). Eight genes were unique in the THF versus p53-/- comparison (UL48, UL68, UL84, UL100, UL106, UL109, UL111, RL5A), and three genes in the HFF versus p53-/- cell comparison (UL14, UL16, US2). When comparing HFF and THF cells, only US2 showed a significant difference. The ratio (HFF versus p53-/- divided by THF versus p53-/-) of the expression levels of the eleven shared genes from the HFF versus p53-/- and THF versus p53-/- comparisons was an averaged 1.2, indicating that, with the exception of US2, these two cell lines behaved similarly with respect to p53-driven viral gene expression.

Keywords: time course, virus, cytomegalo, hhv5, infection, p53 Each slide consisted of 4 arrays. Each array consisted of 305 control features, 1265 cellular gene features and 670 viral gene features. The study was performed on 6 slides (HFF-THF, HFF-p53-/-, THF-p53-/- at 12 and 24 hpi). 3 arrays per slide were hybridized with 3 biological replicates of labelled RNA, the 4th array was hybridized with an equimolar mixture of the 3 biological replicate samples. This array was used for control purposes only, and the results were not used for downstream calculations. Each slide was stripped and reprobed two times to provide 3 technical replicates of each sample. As our experiments concentrated on viral genes and their expression, cellular genes were not further analyzed in this study.
