Expression of lung tissue ET-1 proteins was measured using Western blot analysis. The bar graph represents the relative ET-1 levels (percent of Control d1 ± SEM). #P <0.05 as compared with Control d1, IUGR d1, Control 10 weeks, and IUGR 10 weeks groups, respectively; **P <0.05 as compared with Control d1, IUGR d1, Control 10 weeks, IUGR 10 weeks, and Control OVA groups, respectively; note increased ET-1 expression in the IUGR OVA group. β-actin protein expression served as an internal control and was used to normalize the protein band intensity (n = 4).
