Figure Lengend Snippet: Target identification of MY in protecting oxidative damage in TBHP‐treated C2C12 myotubes. (A) The structure of the probe MY‐P. (B) Pull‐down labeling with MY‐P in C2C12 myotubes. CBB: Coomassie Brilliant Blue. (C) Volcano plot of MY‐P binding proteins compared with control group (10 µM MY‐P). (D) Pull‐down/Western blotting identified the target protein PRDX5. (E) The PRDX5 expression in Gast muscle from young or aged mice. ## p < 0.01, young versus aged. ** p < 0.01, aged versus aged+MY.L. && p < 0.01, aged versus aged+MY.H. (F) The PRDX5 expression in TBHP‐treated C2C12 myotubes. ## p < 0.01, vehicle versus TBHP, * p < 0.05, ** p < 0.01, MY versus TBHP. (G) ITC titration of MY (100 µM) into recombinant PRDX5 protein (5 µM). (H) Western blotting‐based CETSA validation of thermal stabilization of PRDX5 in response MY treatment at the concentration from 0 to 100 µM. β‐Actin was used as a control. Data are displayed as mean ± SD, n = 6.
Article Snippet: The protein sample, complexed by MY and recombinant PRDX5 protein (synthesized by ChinaPeptides, Shanghai, China), was dialyzed into the ITC buffer overnight.
