Proinflammatory Cytokines Increase Vascular Endothelial Growth Factor Expression in Alveolar Epithelial Cells

Figure 2

Northern blots showing effects over a time course of cytokines on VEGF RNA expression after stimulation with TNF-α. Results are expressed as fold-change compared to time zero, normalized to β-actin. Graphic analysis is at the bottom of the figure; all time points show increased expression versus time zero but do not differ from each other, though an apparent peak effect is suggested at 2 hours. Blots are representative of 4 individual experiments. .
