Gene expression was determined by semi-quantitative RT-qPCR from RNA isolated from frozen liver samples. The mean ΔCt value of the WT-NFNC dietary group was set as the reference to which all samples were compared using the ΔΔCt methodology. The mean relative expression and SD is shown to indicate the variability of the response to dietary stimulus.

^*p<0.05 vs. NFNC diet by one-way ANOVA with Tukey post-hoc tests, n=9–10.
