Abstract
Nrf2 is a transcription factor that regulates the induction of an expansive set of antioxidant proteins that act in synergy to remove reactive oxygen species (ROS). We have recently discovered that Nrf2 signaling is involved in the induction of antioxidant response in ethanol-exposed embryos. We have also demonstrated that chemically induced transcriptional activation of Nrf2 and subsequent induction of a broad spectrum of antioxidant proteins can act as an endogenous protective system against ethanol-induced oxidative stress and apoptosis in early mouse embryos. This chapter describes the methods used to analyze Nrf2-mediated transcriptional induction of antioxidant response in mouse embryos. Data which have been generated by using these methods have also been included to provide examples of their usefulness in evaluating Nrf2-mediated antioxidant response in early embryos.
