(A) Western blot analysis of phosphorylated Src, total Src, and phosphorylated PTEN, in DMSO and C188–9 HUVECs following exposure to histamine (100 µM). (B–C) Western blot analysis of phosphorylated VE-cadherin, total VE-cadherin, active (non-phosphorylated) β-catenin, total β-catenin, phosphorylated Src, total Src, phosphorylated PTEN, total PTEN, and phosphorylated STAT3, in wild type and AD-HIES HUVECs following exposure to histamine (100 µM). Data are represented as the mean ± S.E.M. *p<0.05. (D) Real time PCR analysis of mir17–95 RNA expression in IL-11 (100ng/ml) treated wild type and AD-HIES HUVECs. Data are representative of 3 independent experiments. (E) Western analysis of SIAH1 and E2F1 expression in wild type and AD-HIES. Data are representative of 2 independent experiments. (F) Analysis of cytoplasmic verses nuclear active β-catenin in wild type and AD-HIES HUVECs.
