Mean normalised expression (MNE) of genes regulating oxidative and nitrosative stress [NOX‐4 (A), HMOX‐1 (B), NOS‐2 (C) and NOS‐3 (D)] and anti‐oxidant enzymes [SOD‐1 (E), SOD‐2 (F), CAT (G) and GPX (H)] in the lung of the late‐gestation sheep fetus. Data are expressed as mRNA MNE ± SD in normoxic (white bars) and hypoxic (black bars) pregnancies. *
P < 0.05, P‐value for mean difference between groups.
