Effect of glycosphingolipid synthesis inhibitors on PCBG-mediated IL-8 secretion from 1HAEo-airway epithelial cells. A. Cells were incubated with different concentrations of PDMP for 72 hours prior to stimulation with 100 ug/ml of PCBG, and the cells incubated an additional 14 hours. Supernatants were assayed for IL-8 as described. Data were analyzed with one-way ANOVA and posttest Bonferroni comparison (***denotes p < 0.001). The data shown is representative of three independent experiments. B. 1HAEo- cells were incubated for 72 hours in the presence of PDMP at the concentrations indicated, or media alone prior to stimulation with PCBG for 30 min. Phospho-p44-42 was analyzed by western blot and actin was assessed in parallel to verify equal loading. C. Densitometry analysis of phospho- p44/p42 to Actin ratio.
