Project description:To investigate the role of gene expression during Newcastle disease virus (NDV) infection.The NDV GM strain was used to infect DEF cells with 1moi, while an uninfected group was set up as a control.
Project description:We report the genetic plasticity of Newcastle disease virus. We introduced insertional mutation in the virus genome and checked fitness by comparing distribution of mutants in passage 1 and passage 2.
Project description:Airway epithelial cells from 3 different breeds of chicken infected with Newcastle Disease virus were sequenced and compared to cells from uninfected control birds. The 3 breeds were an indigenous breed, commercial Rhode Island Reds and a hybrid breed (Kenbro).
Project description:To investigate the role of m6A modification during Newcastle disease virus (NDV) infection We then performed gene expression profiling analysis using data obtained from RNA-seq and MeRIP-seq of NDV infected CEF cells and normal cells.
Project description:Newcastle disease virus (NDV) is an avian virus that selectively replicates and kills many different types of cancer cells and is being developed for cancer treatment. Our aim was to establish persistent infection in EJ28 and TCCSUP bladder cancer cells and identify the dysregulated genes and disrupted molecular pathways associated with persistent infection.
Project description:Whole transcriptome analysis of two genetically distinctinct inbred chicken lines during NDV infection and heat stress. Background: Newcastle disease virus, in its most pathogenic form, threatens the livelihood of rural poultry farmers where there is a limited infrastructure and service for vaccinations to prevent outbreaks of the virus. Previously reported studies on the host response to Newcastle disease in chickens have not examined the disease under abiotic stressors, such as heat, which commonly experienced by chickens in regions such as Africa. The objective of this study was to elucidate the underlying biological mechanisms that contribute to disease resistance in chickens to the Newcastle disease virus while under the effects of heat stress. Results: Differential gene expression analysis identified genes differentially expressed between treated and non-treated birds across three time points (2, 6, and 10 days post-infection) in Fayoumi and Leghorn birds. Across the three time points, Fayoumi had very few genes differentially expressed between treated and non-treated groups at 2 and 6 days post-infection. However, 202 genes were differentially expressed at 10 days post-infection. Alternatively, Leghorn had very few genes differentially expressed at 2 and 10 days post-infection but had 167 differentially expressed genes at 6 days post-infection. Very few differentially expressed genes were shared between the two genetic lines, and pathway analysis found unique signaling pathways specific to each genetic line. Conclusions: The findings in this study confirmed our hypothesis that the Fayoumi line was more resistant to Newcastle disease virus infection compared to the Leghorn line. Fayoumi had significantly lower viral load, higher viral clearance, higher anti-NDV antibody levels, and fewer viral transcripts detected compared to Leghorns. Fayoumis activated immune related pathways including SAPK/JNK and p38 MAPK signaling pathways at earlier time points, while Leghorn would activate these same pathways at a later time. Further analysis revealed activation of the GP6 signaling pathway that may be responsible for the susceptible Leghorn response. Interaction analysis demonstrated substantial differences in response patterns between the two genetic lines that was not observed from the within line contrasts. This study has provided novel insights into the transcriptome response of the Harderian gland tissue during Newcastle disease virus infection while under heat stress utilizing a unique resistant and susceptible model.
