Cells were incubated with various concentrations of gigantol, SA and their combination in presence of high glucose (50 mM, containing medium) for 72 h. The cell viability of normal group (5.56 mM glucose), osmolarity control group and model group were 100 ± 0.89 %, 98.33 ± 0.24 % and 28.23 ± 1.12 %, respectively. Cells were treated for 72 h, respectively. independent experiments. Data were expressed as mean ± SD (n = 3), ^* P < 0.01 vs all other groups
