Confirmation of gene expression differences by RT-qPCR between DBA/2 and C57BL/6 mice at day 14 following C. immitis infection. The fold change for each gene, calculated by dividing the expression level in DBA/2 mice by the expression level in C57BL/6 mice is presented for RT-qPCR data (grey bars). These fold change differences are also compared to microarray results (black bars) for each gene. For the RT-qPCR data, gene expression was assessed using 2 independent samples from C57BL/6 mice and 3 independent samples from DBA/2 mice. RT-qPCR gene expression data (2-∆∆CT) was averaged within mouse strains and then used to calculate log2 fold change values between strains for direct comparison to microarray data. A log2 fold change of 1 equates to an actual fold change of 2. A positive fold change indicates the gene was expressed to a greater extent in DBA/2 mice, and a negative fold change means higher expression in C57BL/6. An asterisk (*) indicates that the gene was significantly differentially expressed (p <0.05, t-test) between mice strains at day 14.
