title: Genetic profile of alloxan-induced diabetes-susceptible mice (ALS) and-resistant mice (ALR).
abstract: Two inbred strains from a foundation stock derived from Crj: CD-1 (ICR) mice were established after more than 20 generations of full-sib mating, and by simultaneous selective breeding for developing and not developing diabetes after alloxan administration (45 mg/kg in males, 47 mg/kg in females). To elucidate the genetic background of the two inbred strains, i. e., alloxan-induced diabetes-susceptible (ALS) strain and alloxan-induced diabetes-resistant (ALR) strain, their biochemical genetic markers and immunogenetic markers were examined. 1) For both strains, investigation of biochemical genetic markers at 19 loci and immunogenetic markers at 11 loci revealed no variation in any gene within the same strain, showing to be homogeneous, thus indicating establishment of the inbred strains. 2) The two strains differed from each other at 2 loci of biochemical genetic markers and at 5 loci of immunogenetic markers. 3) The ALS and ALR strains can be regarded as new inbred strains derived from ICR mice. 4) The results show that the marker genes of the two strains are different at 7 loci, but it remains unclear whether or not these genes are involved in the difference between the two strains in susceptibility to alloxan.
