Project description:To delineate cellular processes involved in NiV infection, we have employed whole genome microarray expression profiling as a discovery platform to identify the upregulated and downregulated genes. Total RNA was collected from infected cells and uninfected controls. Cy3 labeled cRNA is used for hybridization platform Agilent Human 4 x 44K gene expression array.
Project description:To delineate cellular processes involved in NiV F, G, and FG combination, we have employed whole genome microarray expression profiling as a discovery platform to identify the upregulated and downregulated genes. Total RNA was collected from transfected cells and untransfected controls. Cy3 labeled cRNA is used for hybridization platform Agilent Human 4 x 44K gene expression array.
Project description:Nipah virus (NiV) is a recently emerged zoonotic Paramyxovirus that causes regular outbreaks in East Asia with mortality rate exceeding 75%. Major cellular targets of NiV infection are endothelial cells and neurons. To better understand virus-host interaction, we analysed the transcriptome profile of NiV infection in primary human umbilical vein endothelial cells. We found that NiV infection strongly induces genes involved in interferon response in endothelial cells. Among the top ten upregulated genes, we identified the chemokine CXCL10 (interferon-induced protein 10, IP-10), an important chemoattractant involved in the generation of inflammatory immune response and neurotoxicity. We performed microarray gene expression profiling of NiV infected HUVEC cell (2 replicates) and of uninfected HUVEC cell (2 replicates).

Project description:Nipah virus (NiV) is a highly pathogenic, negative strand RNA paramyxovirus that has recently emerged from flying foxes to cause serious human disease. To study the poorly-understood role of nonstructural NiV proteins in NiV pathogenesis, we generated recombinant viruse lacking the expression of accesory NiV C protein (NiVM-bM-^HM-^FC). To analyse the molecular basis of NiVM-bM-^HM-^FC attenuation we have used the gene microarray approach to study early changes of gene expression in infected primary human endothelial cells, which is a major cellular target of human NiV infection. We performed microarray gene expression profiling of NiV infected HUVEC cell (2 replicates), of uninfected HUVEC cell (2 replicates) and of NiVM-bM-^HM-^FC infected HUVEC cell (2 replicates).
