Effect of O3 on GSR expression in the lungs of WT and TLR4−/− mice. WT and TLR4−/− mice were exposed as neonates (A) or adults (B), to O3 or filtered air (FA). GSR expression was analyzed by rt-qPCR at 6 h post-exposure. Data are mean ± SEM values of GSR expression, normalized to GAPDH expression (n = 3–5 mice/group). *: p < 0.05, compared with FA-exposed control group. (EPS 101 kb)
