Brain cell damage that results from oxidative toxicity contributes to neuronal degeneration. The transcription factor nuclear factor‑E2‑related factor 2 (Nrf2) regulates the expression of heme oxygenase (HO)‑1 and glutathione (GSH), and serves a key role in the pathogenesis of neurological diseases. Brassica rapa is a turnip that is unique to Ganghwa County, and is used mainly for making kimchi, a traditional Korean food. In the current study, brassicaphenanthrene A (BrPA) from B. rapa was demonstrated to exhibit protective effects against neurotoxicity induced by glutamate via Nrf2‑mediated HO‑1 expression. Similarly, BrPA increased the expression of cellular glutathione and glutamine‑cysteine ligase genes. Furthermore, BrPA caused the nuclear translocation of Nrf2 and increased antioxidant response element (ARE) promoter activity. Nrf2 also mediated HO‑1 induction by BrPA through the PI3K/Akt and JNK regulatory pathways. The results of the present study indicated the neuroprotective effect of BrPA, a natural food component from B. rapa.
