cAMP-induced expression of CLDN5 and OCLN is mediated by PKA. (A) HUVEC were pretreated with H-89 for 30 minutes and stimulated with cAMP or its derivates for up to 72 h. mRNA expression of OCLN and CLDN5 were determined by real-time qPCR and normalized to expression of HPRT-1 (n = 3). (B) Shown are representative western blot images of HUVEC pretreated with H-89 for 30 minutes and stimulated with cAMP derivates for up to 72 h. Protein amounts of tubulin served as loading control (n = 2).
