| Research Abstract |
1) We have obtained F2 mice by mating P8 strain of Senescence Accelerated Mouse (SAMP8) exhibiting age related learning and memory dysfunction with Japanese wild mouse derived JF1 strain showing normal phenotype. We have performed genome-wide QTL analysis on these F2 mice at the age of 5 month by Step Through experiment with more than 120 genetic markers, and found four significant QTL loci on chromosomes 1, 13 and 15. Interestingly, while the candidate loci on Chromosomes 1 and 13 were derived from SAMP8 background, two loci on chromosome 15 were found to be from JF1 background despite it was used as normal control.
2) Three speed-congenic strains carrying either SAMP8 derived chromosomes 1, 13, or 15 in JF1 background were established by backcrossing F1 strain with JF1 strain.
3) By exhaustive analysis of each candidate regions, we found 3 and 1 genes on chromosomes 1 and 13 carry polymorphisms whose amino acid replacements were specific to the SAM strain, respectively. In 2 loci on chromosome 15, we found 7 and 2 genes carrying polymorphisms associated with amino acid replacements in JF1 strain, respectively.
4) The SAM strain specific polymorphism on chromosome 13 was found in a gene coding for an ion channel. When this gene was expressed in cultured cells, we found difference in ion permeability compared with normal control by patch clump methods. This difference suggests the involvement of the ion channel in learning and memory dysfunction although further characterizations are needed.
