Fig. 3

Analysis of blood levels of molecules relevant to nerve pathology in 10-month-old AAV9-Mpz.GJB1 treated (GJB1) Gjb1-null mice compared to AAV9-Mpz.Egfp (mock) treated littermates, as well as age-matched WT and untreated Gjb1-null mice: A Neurofilament light (NF-L) plasma concentration is increased in Gjb1-null (n = 5) compared to WT (n = 8) mice and shows significant amelioration in post-onset treated mice compared to mock treated mice (n = 6 per group). B: Neural cell adhesion molecule-1 (NCAM-1) serum levels were similarly increased in untreated Gjb1-null (n = 4) compared to WT (n = 3) mice and showed significant improvement in treated compared to mock-treated group (n = 7 per group) (one-way ANOVA with Bonferroni post-test; *P < 0.05, **P < 0.01 and ***P < 0.001).
