Figure 7. Exendin-4 reduces t-BHP-induced ROS production.

Cells were treated with or without Exendin-4 and then with t-BHP for different intervention times, collected, stained with 2 µM HE and analyzed with an absorbance microplate reader. Values are expressed as percentages of total cell counts. The data are expressed as the means±S.D. (n = 6). a, b, c, d and e indicate the t-BHP groups and Exendin-4 groups at different intervention times (p<0.05).
