[The 1xC3 panel of recombinant inbred mouse strains. Presence or absence of pathologic neurologic traits of one of parental strains].
Mice from the earlier developed recombinant inbred strains (RIS), which were derived by crossing 101/HY mice (carrying the mut-1 allele determining increased susceptibility to the mutagenic action of alkylating compounds) with C3H/Sn mice (lacking this trait), were tested for the presence of two neurological pathologies, audiogenic epilepsy and splitting of pyramidal cell layer of the CA3 hippocampal field (specific only to 101/HY mice). It was demonstrated that segregation of RIS relative to these traits was independent from the presence or absence of the mut-1 allele. These findings suggested the appearance of mut-1-independent mutations in the 101/HY mice, which resulted in the development of neurological pathologies. The appearance of such mutations can be the consequence of the genetic repair defects, earlier observed in the mice with the same genotype, or they can be caused by other reasons.
