Fig. 5. Tea polyphenol treatment reduces MDA levels in PM2.5-treated A549 cells.

Fig. 5

The A549 cells were exposed to 50 μg/mL of PM2.5 for 24 hours and then treated with tea polyphenols (0.1 to 10 μg/mL) for an additional 24 hours. The MDA levels are expressed as nanomoles of substrate (nmol) converted to reaction product relative to mg protein added to the assay (mg prot) and graphed as the mean ± SD of n=6 samples per condition. The asterisks indicate statistically different conditions with post hoc pairwise comparisons indicated with connecting lines for (#) P< 0.05, (##) P< 0.01 and (*) P< 0.001.
