Notes

• Experiment
  Microarray analysis was used to identify candidate genes for colitis susceptibility QTLs. Messenger RNA was analyzed for expression differences between colitis susceptible inbred strain C3H/HeJBir-Il10^tm1Cgn and colitis resistant inbred strain C57BL/6J-Il10^tm1Cgn.
  
  Capn3 (67.2 cM) on mouse Chromosome 2 is upregulated 1.5- to 2-fold in C3H/HeJBir-Il10^tm1Cgn animals. This candidate gene maps to the Cdcs3 (cytokine deficiency colitis susceptibility 3) interval centered near 65 cM.
  
  Gbp1 (67.4 cM) on mouse Chromosome 3 is upregulated over 15-fold in C3H/HeJBir-Il10^tm1Cgn animals. This candidate gene is known to be polymorphic between C3H/HeJBir and C57BL/6J and exhibits expression differences in these parental wild type strains. Gbp1 maps to the Cdcs1 (cytokine deficiency colitis susceptibility 1) interval centered near 62 cM. Adh1 at 71.2 cM and Bglap2 at 42.6 cM also map to the same QTL interval. Adh1 is upregulated 1.5- to 2-fold, and Blgap2 is upregulated 2- to 5-fold, in C3H/HeJBir-Il10^tm1Cgnanimals.
  
  Pla2g2a (68 cM) on mouse Chromosome 4 is upregulated over 15-fold in C3H/HeJBir-Il10^tm1Cgn animals. This candidate gene is known to be polymorphic between C3H/HeJBir and C57BL/6J and exhibits expression differences in these parental wild typestrains. Pla2g2a maps to the Cdcs9 (cytokine deficiency colitis susceptibility 9) interval centered near 71 cM. Moreover, C57BL/6J animals are known to carry the frameshift mutation Pla2g2a^Min1-s resulting in multiple intestinal neoplasia. The human ortholog PLA2G2A maps near a irritable bowel disorder (IBD) susceptibility locus named IBD7. Gnb1 (79.4 cM) also maps to the Cdcs9 QTL interval and is upregulated 2- to 5-fold in C57BL/6J-Il10^tm1Cgn animals. Errfi1 (formerly 1300002F13Rik) and Tceb3 also map to the Cdcs9 interval and are upregulated 1.5- to 2-fold in C57BL/6J-Il10^tm1Cgn animals.
  
  Areg (51 cM) on mouse Chromosome 5 maps near the Cdcs10 QTL interval centered around 45 cM. This candidate gene is upregulated 1.5- to 2-fold in C57BL/6J-Il10^tm1Cgn animals.
  
  Mtmr7 maps to mouse Chromosome 8 near the Cdcs4 interval centered around 21 cM. This candidate gene is upregulated over 15-fold in C57BL/6J-Il10^tm1Cgn animals.
  
  Cd14 (31 cM) on mouse Chromosome 18 is upregulated 5- to 15-fold in C3H/HeJBir-Il10^tm1Cgn animals. CD14 also exhibits expression differences in parental wild type strains C3H/HeJBir and C57BL/6J. This candidate gene maps to the Cdcs6 (cytokine deficiency colitis susceptibility 6) interval centered near 41 cM. The human ortholog CD14 maps near a human irritable bowel disorder (IBD) susceptibility locus named IBD5.
  
  Glo1 (16 cM) and Ly6g6c on mouse Chromosome 17 are upregulated 2- to 5-fold in C57BL/6J-Il10^tm1Cgn animals. This candidate gene maps to the Cdcs5 (cytokine deficiency colitis susceptibility 5) interval centered near 19 cM. Hspa1a (18.9 cM) and Hspa1b (18.9 cM) also map to Cdcs5 and are upregulated 1.5- to 2-fold in C57BL/6J-Il10^tm1Cgn animals.
