Summary
Our data showed a trend for increase in NAD+-levels in blood; only in the D2-mdx NR-treated mice the NAD+-levels were slightly increased. These markers were elevated in mdx models compared to controls, but not affected by the NR treatment. Histological analysis of muscle tissues indicated a mild treatment effect in D2-mdx mice. Based on our results, testing NR treatment in clinical trials in DMD patients is not warranted.
