Effect of genetic background on inflammatory gene expression in CF mouse small intestine. RNA expression levels were determined by quantitative real-time RT-PCR using gene-specific primers. Data are expressed relative to GAPDH mRNA, which does not vary between wild type and CF mice. Data are means ± SEM. (*) CF vs wild type on the B6 background, P < 0.005; (+) CF on the mixed background vs CF on the B6 background, P < 0.05 by ANOVA with a post-hoc Tukey's test. There were no significant differences for any of the 6 genes comparing: wild type B6 mice vs wild type mixed background; or CF mice on the mixed background vs wild type on either background. There were 8–11 samples analyzed per group for each gene.
