For gluconeogenesis, the Pck1 mRNA levels in ZL and ZDF rats fed the VAD-HF diet were higher than those in ZL and ZDF rats fed the VAM-HF diet, respectively, as shown in Figure 8D. Interestingly, the ZL rats fed the indicated diets had higher Pck1 mRNA levels than the ZDF rats fed the same diet, respectively. The gene discussed is PCK1; the disease is hydrops fetalis.
