Figure 3From: Hypoxia down-regulates expression of secretory leukocyte protease inhibitor in bronchial epithelial cells via TGF-β1SLPI expression is down regulated by TGF-β1. SLPI concentrations in the cell medium from human bronchial epithelial cells stimulated with TGF-β1 (A), or in the absence or presence of 1 ng/ml TGF-β1 (B). The figure shows means and SEM of at least three independent experiments.Back to article page
