Figure 3: Effect of pummelo on total GSH levels. H9c2 cells were treated with doxorubicin (DOX, 0.1 μM) with or without coincubation with pummelo (CM) at three concentrations as indicated in the figure (10, 100, 1000 μg/mL). The total GSH (tGSH) levels were calculated as described in Materials and Methods. versus vehicle treated cells (CTRL); versus DOX.
