Outline of Final Research Achievements |
Artificially controllable transgene expression system is indispensable tool for production of various disease model animals to precisely mimic human disease states. In the present study, we successfully generated transgenic marmoset line with tetracyclin-inducible gene expression system for neurodegenerative disease model. Mutant human ataxin 3 gene with 120 CAG repeats controlled by tetracycline-inducible system was introduced into marmoset embryos via lentiviral transduction. A total of seven live offspring were obtained. They and their fibroblast cells treated doxycycline revealed inducible transgene expression compared to before treatment. Moreover, a total of five second-generation (F1) offspring were obtained from founder marmosets and one was transgenic, showing successful germline transmission of transgene. In conclusion, the present study generated transgenic marmoset line having mutant human ataxin 3 gene controlled by tetracycline-inducible system.
