This trend was further confirmed at the protein level by Western blot analysis, which showed a corresponding reduction in MAPKAPK2 protein abundance with increasing H 2 O 2 concentrations (Supplementary Figure S1B)

These findings translate conceptually to human tendon injuries like those occurring in the shoulder
