differentially expressed genes in NDV infected chicken brains. differentially expressed genes in NDV infected chicken brains

Cellular proteins in central nervous system involved in avian neurotropic virus infection remains completely unknown. To investigate host gene expression profile in NDV infected SPF chicken brains, The microarray initial analysis was performed at LC-Bio (Hangzhou, China). A 44K Agilent chicken whole genome chip (43,803 probes) (Agilent Technologies, USA) was used for gene microarray analysis from F48E9-, LaSota-infected and mock-infected brains through intraocular-nasal routes.The chicken brains were collected at 5 day post infection. The significance analysis was used to evaluate the differences in gene expression. P and fold change (FC) values represent the alteration tendency of gene expression between experimental and control groups. The genes (FC>2) were input in Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis for DEGs. Overall design: F48E9-, LaSota-infected and PBS (control)-infected brains through intraocular-nasal routes in 100000 pfu/100μl/chicken were collected at 5 day post infection.The data from F48E9- and LaSota-infected brains were compared to mock (PBS)-infection.
