Notes

• Experiment
  The correlation between gene expression and dietary interaction was examined in a population of (BALB/cStCrlfC3H/Nctr x VY/WffC3Hf/Nctr-A(vy)/a)F1 animals. A/a and A/A^vy animals were placed on a 70% (calorie restricted) or 100% (non-restricted) diet andliver mRNA levels were assessed for over 18,000 genes using DNA microarrays. Twenty-eight known genes showing statistically significant differential expression between the 70% and 100% calorie diets and A/a and A/A^vy genotypes mapped near known diabesity QTLs. These genes may be considered further for candidate genes.
  
  On mouse Chromosome 5, Pdgfra (42 cM) showed differential expression between A/a and A/A^vy animals on the unrestricted diet. Diabesity QTLs Dbsty2 (45 cM), Bw8 (42 cM), and Bwob (44 cM) map near this candidate gene. Another candidate gene, Shrm (52 cM), showed differential expression between the restricted and unrestricted diets on the A/a background as well as between A/a and A/A^vy animals on the restricted diet. Diabesity QTL Igfbp3q1 (58 cM) maps near Shrm. Mdh2 (78 cM) shows differential expression between the restricted and unrestricted diets on a A/A^vy background. Diabesity QTL Bw13 (81 cM) maps near candidate gene Mhd2.
