Effect of TRC105 on 7K-induced Eng signaling pathway in HAoECs. (A) pSmad1/5 protein levels; (B) pSmad2/3 protein levels. To analyze Smad signaling, cells were serum-starved in EBM-2 medium for 22 h and then pretreated with 300 μg/ml TRC105 for 90 min. HAoECs were stimulated with 10 μg/ml 7K for 30 min after TRC105 pretreatment. The data are presented as mean ± S.E.M (n = 6). ns, p ≥ 0.05; *p < 0.05, using Kruskal–Wallis test for comparisons among control, TRC105, and 7K, and ††p < 0.01; †††p < 0.001, using Mann–Whitney test for comparison between 7K vs TRC/7K.
