Figure 5. The effects of hyperoxia on scavenger receptor expression in Nrf2+/+ and Nrf2−/− alveolar macrophages.

The mRNA expression levels of Marco (left panel) and Msr1 (right panel) in macrophages from room air, hyperoxia-exposed and recovered mice were determined using real-time PCR analysis. The values represented are means with SD. *P ≤ 0.05 vs. room air control of the same genotype; † P ≤ 0.05, Nrf2−/− vs. Nrf2+/+ cells exposed to hyperoxia.
