Endothelial cells express neuronal stable tubule-only polypeptides (N-STOP). A: N-STOP (110 kDa) is expressed in PMVEC (right) but not in HeLa cells (left). B: in addition, N-STOP is expressed in pulmonary artery endothelial cells (PAEC), as well as pulmonary vein endothelial cells (PVEC). C: data are representative of 4 independent experiments. Relative area is the ratio of the area of N-STOP measured by densitometry of Western blot analysis and the area of α-tubulin measured by densitometry of Western blot analysis. Values are means ± SD. Statistical significance was evaluated using one-way ANOVA (Kruskal-Wallis statistic; P = 0.9260).
