SLPI expression in bronchial epithelial cells is reduced in response to hypoxia. A) SLPI concentrations in cell medium from primary human bronchial epithelial cells grown under normal oxygenation (21% O2) or under hypoxic conditions (1% O2) (n = 5). B) SLPI mRNA levels from bronchial epithelial cells incubated at 21% or 1% O2. The values of fold change were calculated by normalizing to the data from the 21% O2 samples. The figure shows means and SEM of eight independent experiments.
