| Outline of Final Research Achievements |
It was found that development of ulcerative colitis under the compromised Abcb1a function is influenced by modifier genes located on chromosomes 16 and 13 by using SAMP1 and FVB/N mouse strains that have a loss-of-function mutation in the Abcb1a gene, which functions in the exclusion of a wide range of drugs from the cell. It was also revealed that one of the modifier genes is located in the interval of approximately 7 Mb on chromosome 16. Furthermore, a missense nucleotide substitution polymorphism in the Ifnar1 gene was discovered between the two mouse strains that the SAM strains. However, it was not clear if the polymorphism is actually involved in the determination of development of ulcerative colitis under the compromised Abcb1a function.
