Project description:Edwardsiella tarda is a Gram-negative bacterial pathogen that can infect a wide range of freshwater and marine fish. However, the immune evasion mechanisms of Edwardsiella tarda is not fully understood. We found that Edwardsiella tarda infection generally significantly upregulated and downregulated a lot of immune-related genes of zebrafish ZF4 cells using RNA-seq technology.
Project description:This SuperSeries is composed of the following subset Series: GSE28481: Transcriptome analysis of the zebrafish embryonic host response to Edwardsiella tarda infection using a static immersion systems [experiment A] GSE28485: Transcriptome analysis of the zebrafish embryonic host response to Edwardsiella tarda infection [experiment B] Refer to individual Series
Project description:To determine the global gene transcriptional changes in channel catfish anterior kidney after immersion vaccination with attenuated Edwardsiella ictaluri compared to sham vaccinated catfsih control. The attenuated Edwardsiella ictaluri used for vaccination was Aquavac-ESC which was commercially available. A six chip study using total RNA samples including 3 control and 3 vaccinated samples. Each RNA sample used for microarray was poold fish anterior kidney samples (5 fish anterior kidney samples were pooled as one). Each chip measrues the expression level of 65,182 genes. For each sequence, 3 probes were selected. Two copies were prepared on arrays.
Project description:To determine the global gene transcriptional changes in vaccinated channel catfish anterior kidney after immersion challenge with a virulent Edwardsiella ictaluri compared to sham vaccinated catfish control. The attenuated Edwardsiella ictaluri used for vaccination was Aquavac-ESC which was commercially available, the virulent strain of Edwardsiella ictaluri is the AL93-58 strain. A six chip study using total RNA samples including 3 controls (no vaccination, no challenge) and 3 treated groups (challenge after vaccination). Each RNA sample used for microarray was pooled fish anterior kidney samples (5 fish anterior kidney samples were pooled as one). Each chip measrues the expression level of 65,182 genes. For each sequence, 3 probes were selected. Two copies were prepared on arrays.
