Figure 4. Effect of native versus pegylated IFN on ET-1 release from HPASMCs.

Figure 4

 = Effect of native 30 ng/mL IFNα2a or IFNα2b versus pegylated (PEG) forms on ET-1 release from human pulmonary artery smooth muscle cells (HPASMCs). Cells were treated with interferons (IFNs) for 24 hours. Data are the mean ± standard error of the mean for n = 8. Within-group analysis was performed using one-way ANOVA followed by a Dunnett's post-test, where * indicates p<0.05 compared to control. Between-group analysis, for the effect of TNFα was performed using two-way ANOVA followed by Bonferroni's post-test where # indicates p<0.05.
