Figure 5.

Cell viability in pCMV-Entry-expressing cells and INS1E-hIAPP-overexpressing cells under oxidative stress conditions. INS-1E cells were incubated in RPMI 1640 medium supplemented with/without 2% fetal bovine serum and/or nitric oxide (2 mM) or hydrogen peroxide (200 μM) for 24 h at 37 °C with 5% CO₂. Cell viability was analyzed by Cell Counting Kit-8. Values are presented as the mean ± SEM of three experiments.
