Project description:Purpose: The goal of this study is to investigate the effect of Zika virus infection on neural stem cells Methods: RNA-Seq transcriptome analysis of neural stem cells infected with Zika virus compared to mock infected
Project description:We repoted the Glioblastoma stem cells(GSCs) infected by two strains of ZIKA virus, the Brazil and Dakar strains. The ZIKV was added into the medium of GSCs for 48 hours, the RNA was harvested after ZIKV infection. We found that the GSCs up-regulated the Type 1&2 interferons after infected by ZIKV
Project description:We explored the utility of oncolytic virus therapy against glioblastoma with Zika virus (ZIKV), a flavivirus that induces cell death and differentiation of neural precursor cells in the developing fetus. ZIKV preferentially infected and killed glioblastoma stem cells (GSCs) relative to differentiated tumor progeny or normal neuronal cells. The effects against GSCs were not a general property of neurotropic flaviviruses, as West Nile Virus (WNV) indiscriminately killed both tumor and normal neural cells. ZIKV potently depleted patient-derived GSCs grown in culture and in organoids. Moreover, mice with glioblastoma survived substantially longer and at greater rates when the tumor was inoculated with a murine adapted strain of ZIKV. Our results suggest that ZIKV is an oncolytic virus that can preferentially target GSCs, and thus, genetically modified strains that further optimize safety could have therapeutic efficacy for adult glioblastoma patients.
Project description:In this study, we show that CD27+ memory like NK cells generated following Zika virus infection exhibited stem-like features viz., self-renewal pathway, differentiation into effector cells and longer telomeres, and greater therapeutic potential than CD27- and naive CD27+ NK cells when adoptively transferred to Zika virus infected mice. In addition, epigenetic landscape of CD27+ memory like NK is markedly different compared to CD27- NK cells.
Project description:Transcriptional profiling of human astrocyte cells (SVG) infected with Zika virus. Goal was to identify temporal changes in gene expression post infected by Zika virus.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:small RNA-seq was utilized to characterize the transcriptome of human neural stem cells infected with Zika virus strains MR766 and Paraiba at MOI 1. Coding and noncoding genes were analyzed to determine transcriptional changes 3 days post-infection.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs. One-condition experment, gene expression of 3A6
