Markers of dystropathology, grip strength (A), and plasma CK (B), in WT and untreated and taurine-treated DMDmdx rats (at 2 doses) aged 12 weeks. * = significantly (p < 0.05) different to WT. Bars represent mean ± SEM and n = 8–10 rats per group. |
Levels of taurine in plasma (A) and muscle (B) in plasma, from WT and untreated and taurine-treated DMDmdx rats (at 2 doses), aged 12 weeks. * = significantly (p < 0.05) different to WT. # = significant (p < 0.05) different to untreated DMDmdx rats. Bars represent mean ± SEM and n = 8–10 per group. |
Markers of inflammation and oxidative stress in WT and untreated and taurine-treated DMDmdx rats (at 2 doses) aged 12 weeks. Levels of plasma neutrophils (A) and muscle MPO (B) and oxidative stress measured as protein thiol oxidation (PTO) (C). * = significantly (p < 0.05) different to WT. $ = significantly (p < 0.05) different to untreated DMDmdx rats. Bars represent mean ± SEM and n = 8–10 per group. |
Muscle function (distance travelled) of 6 dpf WT (dmd+/+), heterozygous (dmd+/−) and homozygous (pc2/pc) dystrophic (dmd−/−) zebrafish treated with either 1 mM taurine or water (control) from 2 to 6 dpf. * = significantly (p < 0.05) different to WT. Bars represent mean ± SEM. For dmd+/+: n = 30, 27, 33 for untreated and n = 27, 22, 26 for taurine-treated; for dmd+/pc2: n = 48, 48, 55 for untreated and n = 56, 62, 55 for taurine-treated, and for dmdpc2/pc2: n = 41, 23, 28 for untreated and n = 32, 25, 37 for taurine-treated.

Levels of taurine in tails of WT (dmd+/+), heterozygous (dmd+/−) and homozygous (pc2/pc) dystrophic (dmd−/−) zebrafish treated with either 1 mM taurine (tau) or water (un) from 2 to 6 dpf. * = significantly (p < 0.05) different to WT. $ = significantly (p < 0.05) different to the untreated of same strain. Bars represent mean ± SEM and n = 4 (pooled samples of 12) per group. PHENOTYPE:

Human plasma levels of taurine in control males and patients with DMD. Compared for healthy normal aged-matched (A–M) controls and patients with DMD: ambulant (2–6 years) and non-ambulant (16–20 years). * = significantly (p < 0.05) different to healthy age-matched control. # = significantly (p < 0.05) different to young healthy age-matched control and ambulant DMD. Bars represent mean ± SEM and n = 8–10 per group. |
