Abstract

Antioxidant response element (ARE)-mediated expression and coordinated induction of genes encoding detoxifying enzymes is one mechanism of critical importance to cellular protection against oxidative stress. In the present report, we demonstrate that nuclear transcription factors Nrf2 and Nrf1 associate with Jun (c-Jun, Jun-B and Jun-D) proteins to upregulate ARE-mediated expression and coordinated induction of detoxifying enzymes in response to antioxidants and xenobiotics. Nrf-Jun association/heterodimerization and binding to the ARE required unknown cytosolic factor(s). Nrf2 containing one mutated leucine in its leucine zipper region was more efficient in upregulation of ARE-mediated gene expression, as compared to Nrf1 with two mutated leucines.
