An overview of microarray data analysed in three immune competent organs of cecropin P1 transgenic trout versus non-transgenic trout. A, Hierarchical clustering of spleen, kidney, and liver samples derived from two families (F703 & F180) of cecropin P1 transgenic trout. Designated numbers after each tissue indicate biological and microarray technical repeats. B, Venn diagram showing numbers of differentially expressed genes (DEGs) identified in the three organs of cecropin P1 transgenic trout. C, A list of genes selected from the 478 DEGs in common among organs related to different biological functions. Color gradient denotes relative degree of expression ratio (transgenic/non-transgenic). D, Comparison of microarray and real-time RT-qPCR results (n = 54; linear regression, R2 = 0.82).
