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 15, Npr3 (6.7 cM) shows differential expression between restricted and unrestricted diets on the A/A^vy background as well as between A/a and A/A^vy animals on the restricted diet. Diabesity QTLs Bw11 (6 cM), Mob4 (6.7 cM), and Dob9 (12.3 cM) map near Npr3. Candidate genes for diabesity QTLs Dbsty4 (49.6 cM) and Bwtq6 (41.2 cM) are D15Wsu75e (46.7 cM), Gpt1 (40.3 cM), Tef (46.7 cM), and H1f0 (46.75 cM). Tef and H1f0both show differential expression between restricted and unrestricted diets on the A/A^vy background. D15Wsu75e shows differential expression between A/a and A/A^vy animals on both the restricted and unrestricted diets. Gpt1 shows differential expression between A/a and A/A^vy animals on the restricted diet.
