Project description:Three small RNA libraries constructed from uninfected HeLa cells or the cells infected with NDV strain Herts/33 at 6 and 12 hr post inoculation were sequenced using an Illumina platform.Three replicates of each group (Mock, NDV-6h and NDV-12h) were prepared and pooled separately for library construction and small RNA Deep sequencing.
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: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: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:Newcastle disease (ND) affects a few hundred avian species including chicken, and the clinical outcome of Newcastle disease virus (NDV) infection ranges from mild to severe fatal disease depending on the NDV pathotype and the host species involved. Japanese quails serve as natural reservoirs of NDV and play important role in NDV epidemiology. While infection of chicken with velogenic NDV results in severe often fatal illness, the same infection in Japanese quails is results in in apparent infection. The molecular basis of this contrasting clinical outcomes of NDV infection is not yet known. We compared global gene expression in spleens of chicken and Japanese quails infected with a lentogenic or velogenic NDVs. We found contrasting regulation of key genes associated with NF-κB pathway and T-cell activation between chicken and Japanese quails. Our data suggests association of NDV resistance in Japanese quails to activation of NF-κB pathway and T cell proliferation.
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:Genotype VIId NDV is characterized by severe tissue damage in chicken lymphoid organs compared to other virulent strains. However, biological basis of this unusual pathological phenotype is unknown. Host response is associated with pathogenicity of Newcastle Disease Virus (NDV). We aim to determine the contribution of host response to the severe tissue destruction in the lymphoid system caused by genotype VIId NDV. We used microarray analysis to evaluate the global transcriptional response in the spleen of chickens infected with genotype VIId NDV strain JS5/05 and genotype IV NDV Herts/33.

We used microarray analysis to evaluate the global transcriptional response in the spleen of chickens infected with genotype VIId NDV strain JS5/05 and genotype IV NDV Herts/33. Chickens were inoculated with JS5/05 or Herts/33 or mock-infected. At day 2 post infection, spleens were isolated from three chickens per group for RNA extraction and hybridization on Affymetrix microarrays. Samples were named as follows: JS5/05 (I4_1_NS,I4_2_NS,I4_3_NS), Herts/33 (H1_NS,H2_NS, H3_NS), control (C1_NS, C2_NS, C3_NS).
