Project description:Data from the VLA lyssavirus genotyping microarray. The array platform for this data is GEO accession GPL8066, and consists of 624 oligos representing two viral families. The data set itself consists of 14 arrays, 7 hybridised with RNA from mice brains infected with 7 genotypes of lyssaviruses, 1 hybridised with RNA from normal mouse brain, and 6 hybridised with RNA from coded samples consisting of infected mouse brains or control mouse brains. Keywords: Lyssavirus genotyping microarray

Statistical analysis of the data was done with DetectiV software (Watson et al., 2007). The median and array methods of normalization were used in the statistical analysis of the results. In the median method, DetectiV software calculates the mean fluorescence for each set of probes and normalised against background fluorescence of all probes, assuming that most probes are not hybridized. The array method utilizes an entire control array, e.g. RNA from a known uninfected animal, as the negative control and all probe values are divided by their respective elements from the control array.
Project description:Street-strain rabies virus primarily replicates in central nervous system without inducing significant immune response or structural damages on neurons, but the manifested symptoms of rabies indicate inherent neuronal dysfunctions in CNS. To understand the underlying state of rabies virus-infected neurons and find probable mechanisms for the neuronal dysfunction, we performed RNA-Seq at multiple time-points. This dataset provides RNA-Seq results of wild-type and mutant rabies virus-infected neuron transcriptome, with clear differential expressions between conditions. Through comparative analysis of different time-points, we have found that the matrix protein of rabies virus plays an important role in early suppression of host gene expression and maintaining control over immune response and other processes. The signaling pathways previously known to interact with rabies virus were confirmed to be modulated in this dataset, and contribute to neuronal function-associated processes. We have verified the regulation of gene expressions that could impact neuronal functions collectively, and demonstrated in calcium imaging that indeed the oscillation of calcium trace in neurons are influenced by rabies virus infection.
Project description:This experiment is part of the project that primarily aims to utilize 3D hydrogel-based hiPSC-derived neuronal model to study rabies virus infection in the central nervous system. Having established the optimal 3D neuronal model, we then investigated the growth kinetics of two strains of rabies virus (TH and CVS-11) and comparatively analyzed the 2D and 3D culture models. We performed a gene expression analysis using NanoString to determine whether changes in gene expression could explain the differences in virus growth kinetics of two strains of rabies virus observed between the 2D and 3D neuronal culture models. Gene expression analysis of the neuropathological pathway observed during rabies virus infection demonstrated a vast number of differentially expressed genes in the 3D model as compared to the 2D model.
