Transcriptomics of heart and muscle tissues of transgenic or mdx mice (DMD disease model) with UAA incorporation systems


ABSTRACT: We constructed the trans/mdx mice as a novel DMD disease model by crossing transgenic mice and mdx mice. The transgenic and trans/mdx mice have UAA incorporation system that can readthrough the nonsense mutation in the dmd gene with additional UAA. The whole transcriptomics of heart and muscle tissues of 5 mouse groups (n=2) were used to determine whether the introduced UAA incorporation system affect the normal gene expression of mice, or the safety of the system. Groups include: a) wild-type C57BL/6N mice; b) transgenic mice; c) mdx mice; d) trans/mdx mice without UAA; e) trans/mdx mice with UAA (50 mg NAEK every 2-3 day, treated for 4 weeks). The total numbers of expressed genes were around 11,000 in all 5 mouse groups. The expression levels of major genes (logFPKM>0) in 5 mouse groups were also close to each other. These data indicated that the UAA incorporation system was safe and could serve as a potential therapeutic strategy for DMD disease. The transgenic mice with UAA incorporation system we constructed could also cross with other nonsense mutation mice to build more functional animal models.
