Effect of Cucumis sativus L. extract (CSE) on LPS induced TLR4 expression. a Expression of TLR4 mRNA in pAECs treated with LPS (10 μg/ml) for different time (1, 7, 24 h) in the presence or absence of increasing doses of CSE (0.02; 0.2; 2 mg/ml). mRNA expression of TLR4 is determined by quantitative PCR; relative expression was calculated as fold of change in respect to the control cells and error bar represents the range of relative expression. Different letters above the bars indicate significant differences. b Representative Western Blot of TLR4 and relative housekeeping α-tubulin were reported. c Expression of TLR4 protein in pAECs treated with LPS (10 μg/ml) in the presence or absence of increasing doses CSE (0.02; 0.2; 2 mg/ml); data shown are representative of at least three independent experiments and represent the mean ± SEM. Different letters above the bars indicate significant differences (p < 0.05 ANOVA post hoc Tukey’s test)
