Project description:Bovine respiratory epithelial cells have different susceptibility to bovine respiratory syncytial virus infection. The cells derived from the lower respiratory tract were significantly more susceptible to the virus than those derived from the upper respiratory tract. Pre-infection with virus of lower respiratory tract with increased adherence of P. multocida; this was not the case for upper tract. However, the molecular mechanisms of enhanced bacterial adherence are not completely understood. To investigate whether virus infection regulates the cellular adherence receptor on bovine trachea-, bronchus- and lung-epithelial cells, we performed proteomic analyses.

Elucidation of the host transcriptomic response to bovine respiratory syncytial virus

Project description:Bovine respiratory disease (BRD) is the leading cause of morbidity and mortality in calves over one month of age. In a controlled challenge study in artificially-reared dairy calves, the influence of the host response to bovine respiratory syncytial virus (BRSV) was examined. Holstein-Friesian calves were either inoculated with BRSV (10^5/ml × 15 ml/animal) (n=12) or mock challenged with phosphate buffer saline (10ml/animal) (n=6). Calves were euthanised on day 7 post-challenge. Bronchial lymph nodes were collected; RNA was extracted and sequenced (75bp paired-end). Sequenced reads were adapter trimmed, quality assessed (FastQC) and aligned to the bovine genome (UMD 3.1) using STAR. Differential gene expression analysis was performed using EdgeR, and pathway and gene ontology analyses were carried out using g:Profiler, IPA and DAVID. There was a clear separation between BRSV challenged and control calves based on log2 fold gene expression changes, despite an observed mild clinical manifestation of the disease. There were 934 differentially expressed genes (DEG) (p < 0.05, FDR < 0.1, fold change > 2) between the BRSV challenged and control calves. Over-represented gene ontology terms, pathways and molecular functions, among the DEG, were associated with immune responses and defense responses to a virus.

Glioneuronal tumor with CLIP2-MET fusion: A case report

Project description:Glioneuronal tumor (GN) is one type of biphasic central nervous system (CNS) tumor that exhibits both glial and neuronal immunohistological characteristics. We report a case of glioneuronal tumor (GN) with a discovery of novel gene fusion of CLIP2-MET resulting from aberrant chromosome 7 abnormalities. The tumor exhibited typical characteristics on histological examinations. We executed an elaborate genomic study on this case including whole-exome sequencing and RNA sequencing. Genomic analysis of the tumor revealed aberrations in chromosomes 1 and 7 and a CLIP2-MET fusion. Further analysis of the upregulated genes revealed substantial connections with MAPK pathway activation. We concluded that the chromosome 7 abnormalities prompted CLIP2-MET gene fusion which successively leads to MAPK pathway activation. We deliberated that MAPK pathway activation is responsible for the oncogenesis of GN based on our case and other previously reported ones.
