Figure 3: S-Allylcysteine (SAC) induces the activation of the transcription factor nuclear factor-E2-related factor 2 (Nrf2) in cerebral cortex. Animals received SAC 100 mg/kg every day for 5 days. Quantification was made by ELISA at 450 nm in nuclear extracts from frontal cortex of rats at 24 h after the last administration of SAC. Values are expressed as mean ± SEM. . versus control group.
