Comparison of (a) mRNA expression levels of NOX4 determined by qRT-PCR and (b) MDA concentrations (nmol/L) determined by spectrophotometry of lung tissue from rats exposed to normoxia (NX), chronic intermittent hypoxia (CIH2x2), or chronic sustained hypoxia (CH). Values are expressed as means and SE. ; ; ; in each group.
