Figure 1.

CSE expression and H₂S level was detected in skeletal muscle in db/db mice and C2C12 myoblasts. A, C, CSE expression was examined by Western blotting. B, D, 7‐azido‐4‐methylcoumarin staining was used to measure intracellular H₂S level. Data shown are means ± SD, n = 4, *P < 0.05, **P < 0.01. Significantly different as indicated. One‐way ANOVA. CSE, cystathionine‐r‐lyase; H₂S, hydrogen sulphide
