Research Summary

Takanori  Amano(Ph.D.)

For development of mouse models which recapitulate pathology of intractable diseases, aging-associated diseases and lifestyle diseases, the genome-editing technology is used to produce knock-in point and multiple mutant mice based on genomic information of patients. The developed mice are analyzed and evaluated through the standard platform built by the International Mouse Phenotyping Consortium. We collaborate with external clinical experts for disease mechanisms and pharmacokinetics to establish POC (proof-of-concept) in preclinical studies. The disease models together with associated information useful for diagnosis, therapies and drug discovery will be distributed to the biomedical research community.
