Effects of corticosterone on the viability of PC12 cells evaluated by MTT assay following incubation with various concentrations of corticosterone for 24 h. Asterisk (*) symbol indicates significant difference (p < 0.05; Games-Howell) in viability relative to the negative control. All data are shown as the mean ± S.D. in triplicates (n = 3).
