Candidate Genes

J:91835

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/Avy 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/Avy genotypes mapped near known diabesity QTLs. These genes may be considered further for candidate genes.

On mouse Chromosome 8, Es22 (43.2 cM) and Cdh3 (53.3 cM) both show differential expression between restricted and unrestricted diets on the A/a background. Diabesity QTL Wg3 (45 cM) mapsnear Es22 and diabesity QTL Bwq3 (56 cM) maps near Chd3.

Mapping and Phenotype information for this QTL, its variants and associated markers

J:68441

Authors indicated that enhanced growth rate in C57BL/6J-Cish2hg/Cish2hg mice may be modulated by other genes associated with growth. 1132 F2 mice from a cross between (C57BL/6J-Cish2hg/Cish2hg X CAST/EiJ)F1's yielded 274 +/+ , 596 hg/+ and 262 hg/hg mice with the hg/hg used in a genome wide scan to find QTLs associated with growth rates. A total of 15 QTLs were mapped. QTLs for total weight gain (wg1 - wg4) mapped to mouse Chromosomes 2, 8, and 11, with wg1 and wg2 mapping to mouse chromosome 2.QTLS for total carcass protein (Carp1-Carp3) mapped to Chromosomes 2, 11 and 17. QTLs for total carcass ash weight (Cara1-Cara3) mapped to mouse Chromosomes 2, 11 and 17. QTLs for percent carcass fat (Carf1 and Carf2) mapped to mouse Chromosomes 5 and 9 and QTLS for femur length (Feml1-Feml3) mapped to mouse chromosomes 2, 9, and 17.
