- W1522198934 abstract "Background and Purpose Nuclear factor erythroid 2‐related factor ( N rf2) is a transcription factor that up‐regulates a diverse array of antioxidant genes and protects cells from oxidative damage. This study is designed to determine whether D ‐ L ‐ s ulforaphane ( SFN ) can protect neural crest cells ( NCCs ), an ethanol‐sensitive cell population implicated in fetal alcohol spectrum disorders, against ethanol‐induced apoptosis and whether protective effects of SFN are mediated by the induction of N rf2‐mediated antioxidant response. Experimental Approach Control, SFN ‐treated or N rf2‐ siRNA transfected NCCs were exposed to ethanol. N rf2 activation, the expression and activities of N rf2 downstream antioxidant proteins, reactive oxygen species generation and apoptosis were determined in control and ethanol‐exposed NCCs . Key Results Exposure of NCCs to SFN alone significantly increased N rf2 activation and the expression of N rf2 downstream antioxidants as well as the activities of the antioxidant enzymes. Treatment of NCCs with SFN along with ethanol significantly decreased ethanol‐induced oxidative stress and apoptosis. In contrast, knockdown of N rf2 by siRNA significantly increased the sensitivity of NCCs to ethanol‐induced oxidative stress and apoptosis. Suppression of N rf2 signalling in NCCs also significantly diminished SFN ‐mediated antioxidant response and abolished the protective effects of SFN on ethanol‐induced oxidative stress and apoptosis. Conclusions and Implications These results demonstrated that N rf2‐mediated antioxidant response plays an important role in the susceptibility of NCCs to ethanol‐induced oxidative stress and apoptosis and that the protection of SFN against ethanol‐induced oxidative stress and apoptosis in NCCs is mediated by the induction of N rf2 signalling." @default.
