Effect of (A) supplemented GSH or menadione (MD) and (B) their mixture on MCB signal in 3T3 fibroblasts. The cells were treated with the modulators for 1 h and stained with MCB for additional 1 h (in the presence of modulators). For co-treatment, the cells were pre-exposed to MD followed by addition of GSH. Mean ± SEM (n = 6, * p < 0.05, *** p < 0.001 vs. Ctrl) are shown; Ctrl is the signal of MCB alone.
