In order to verify the data obtained in the microarray experiment, we confirmed the expression profile of 5 selected genes with different patterns of expression: LY96 is differentially expressed in the same direction in both tissues; SERPINE1 is down-regulated in the brain but up-regulated in the lung after infection; CDC42 and AKT1 are significantly up-regulated in lung tissue only, and PIK3R1 is not significantly differentially expressed. Here, PIK3R1 is linked to infection.
