Effects of H9N2 avian influenza virus infection on metabolite content and gene expression in chick DF1 cells.

ABSTRACT: After viral infection, the virus relies on the host cell's complex metabolic and biosynthetic machinery for replication. However, the impact of avian influenza virus (AIV) on metabolites and gene expression in poultry cells remains unclear. To investigate this, we infected chicken embryo fibroblasts DF1 cells with H9N2 AIV at an MOI of 3. Our aim was to explore how H9N2 AIV alters DF1 cells metabolic pathways to facilitate its replication. We employed metabolomics and transcriptomics techniques to analyze changes in metabolite content and gene expression. Metabolomics analysis revealed a significant increase in glutathione-related metabolites, including reduced glutathione (GSH), oxidized glutathione (GSSG) and total glutathione (T-GSH) upon H9N2 AIV infection in DF1 cells.
