The Transcriptome of Nrf2-Deficient Mice in Cigarette Smoke-Induced Emphysematous Changes

ABSTRACT: Cigarette smoke (CS) imposes a strong oxidative burden on exposed tissues resulting in a severely disturbed oxidant/antioxidant balance, which in the context of chronic exposure is assumed to be a key contributor to CS-related diseases. Because of its emerging central role in orchestrating the general cellular antioxidant response, the pathway leading to the activation of the transcription factor Nrf2 has received mounting attention over the past decade in investigations aimed at elucidating CS-induced patho-physiological mechanisms. To comprehensively characterize the impact of Nrf2 in acute and sub-chronic smoking scenarios, Nrf2 knock-out mice and their wildtype ICR littermates were exposed to either ambient air (sham exposure) or to one of three doses of CS for up to 5 months with two
