Figure 3.
Effects of ergothioneine (EGT), hispidin (HIP), and EGT+HIP on protein carbonyl levels in PC12 cells treated with 30 mM glucose and 30 μM methylglyoxal (GLU + MGO). PC12 cells were pretreated with epalrestat (EPA), aminoguanidine (AMG), ETG, HIP, and EGT + HIP for 2 h and incubated with GLU + MGO or mannitol for 24, 48, and 72 h. Values (means ± SD of triplicate tests) without a superscript letter are significantly different (P < 0.05).
