Abstract

Tert-butylhydroquinone (tBHQ) is a xenobiotic with reported antioxidant properties. tBHQ has been shown to induce nuclear translocation of the transcription factor NF-E2-related factor 2 (Nrf2) to further activate the antioxidant response element (ARE). In turn, the Nrf2/ARE pathway is responsible for the induction of phase 2 antioxidant enzymes that detoxify oxidant promoters from different toxic insults. In this work, the antioxidant and protective actions of tBHQ were explored for the first time on different biomarkers of the neurotoxic model produced by the excitotoxic and pro-oxidant molecule quinolinic acid (QUIN) in rat striatal slices. For comparison purposes, 3-nitropropionic acid was used as reference model. Our results show that tBHQ (25 μM) prevented the QUIN-induced lipid peroxidation and mitochondrial dysfunction. In addition, tBHQ enhanced glutathione-S-transferase activity, partially recovering its depletion induced by QUIN treatment. Our results also demonstrated that tBHQ was able to induce nuclear accumulation of Nrf2 and further antioxidant protection: while QUIN alone decreased the nuclear Nrf2, a treatment with tBHQ preserved the nuclear levels Nrf2 in the presence of QUIN. Therefore, the tBHQ-mediated Nrf2/ARE induction constitutes a signaling-mediated antioxidant strategy and therapeutic tool to be tested in different neurotoxic models.
