- Bradykinin regulates the expression of claudin-5 in brain microvascular endothelial cells via calcium-induced calcium release.
- Zhou L1, Yang B, Wang Y, Zhang HL, Chen RW, Wang YB.Author information 1Department of Neurosurgery, First Affiliated Hospital of China Medical University, Shenyang, People's Republic of China.AbstractTo investigate the mechanism underlying the regulation of claudin-5, a tight junction protein that participates primarily in the constitution of the blood-brain barrier by bradykinin (BK), we established a primary culture of rat brain microvascular endothelial cells (BMECs). BMECs were treated with 10(-5) M BK, and changes in the intracellular Ca(2+) levels were measured by using the sensitive fluorescent dye fluo-3; the expression and distribution of claudin-5 were investigated by immunocytochemistry and Western blot analyses. We did not detect any expression of bradykinin B2 receptors in the BMECs or freshly isolated rat brain microvessels. We found that 10(-5) M BK triggered Ca(2+) transients in BMECs, and further investigations revealed that inositol 1,4,5-trisphosphate receptors (IP3 Rs) and ryanodine receptors (RyRs) on the endoplasmic reticulum (ER) were responsible for the Ca(2+) fluctuation. Consequently, these intracellular Ca(2+) changes that occur in response to BK application were identified as Ca(2+) -induced Ca(2+) release (CICR). Immunocytochemistry and Western blot results demonstrated that 10(-5) M BK could cause the internalization and a decrease in the expression of claudin-5; agonists of IP3 Rs and RyRs, such as IP3 and caffeine, enhanced the BK-induced downregulation of claudin-5, whereas antagonists of IP3 Rs and RyRs, such as 2-APB and ryanodine, abrogated BK's effect on claudin-5. In conclusion, the BK-induced CICR in primary culture BMECs might be the mechanism by which BK modulates claudin-5. © 2014 Wiley Periodicals, Inc.

- Apelin-13 stimulates angiogenesis by promoting cross‑talk between AMP-activated protein kinase and Akt signaling in myocardial microvascular endothelial cells.
- Yang X, Zhu W, Zhang P, Chen K, Zhao L, Li J, Wei M, Liu M.Author information Division of Cardiology, Shanghai 6th People's Hospital, Shanghai Jiao Tong University School of Medicine, State Key Discipline Division, Shanghai 200233, P.R. China.AbstractCurrently, there is major interest in the functions of apelin-13, an endogenous ligand for the orphan G-protein coupled receptor APJ, a receptor that closely resembles the angiotensin receptor AT1. In the present study, the role of apelin-13 in angiogenesis and its mechanism as a novel angiogenic factor in myocardial microvascular endothelial cells (MMVECs) was investigated. It was revealed that apelin-13 can promote proliferation, migration and tube formation in MMVECs. In addition, apelin-13 dose dependently stimulated the phosphorylation of AMP-activated protein kinase (AMPK) and endothelial nitric oxide synthase (eNOS) at Thr-172 and Ser-1179, respectively. The treatment with the AMPK (compound C) and protein kinase Akt/protein kinase B (Akt; LY294002) inhibitor significantly suppressed the apelin‑13-induced AMPK, Akt and eNOS phosphorylation. They also inhibited the apelin13‑stimulated endothelial cell migration and tube formation. Therefore, we hypothesize that apelin-13 promotes angiogenesis through the modulation of AMPK and Akt signaling in MMVECs.

- VEGFA Activates Erythropoietin Receptor and Enhances VEGFR2-Mediated Pathological Angiogenesis.
- Yang Z1, Wang H1, Jiang Y1, Hartnett ME2.Author information 1The John Moran Eye Center, The University of Utah, Salt Lake City, Utah.2The John Moran Eye Center, The University of Utah, Salt Lake City, Utah. Electronic address: me.hartnett@hsc.utah.edu.AbstractClinical and animal studies implicate erythropoietin (EPO) and EPO receptor (EPOR) signaling in angiogenesis. In the eye, EPO is involved in both physiological and pathological angiogenesis in the retina. We hypothesized that EPOR signaling is important in pathological angiogenesis and tested this hypothesis using a rat model of oxygen-induced retinopathy that is representative of human retinopathy of prematurity. We first determined that EPOR expression and activation were increased and that activated EPOR was localized to retinal vascular endothelial cells (ECs) in retinas at postnatal day 18 (p18), when pathological angiogenesis in the form of intravitreal neovascularization occurred. In human retinal microvascular ECs, EPOR was up-regulated and activated by VEGF. Lentiviral-delivered shRNAs that knocked down Müller cell-expressed VEGF in the retinopathy of prematurity model also reduced phosphorylated EPOR (p-EPOR) and VEGFR2 (p-VEGFR2) in retinal ECs. In human retinal microvascular ECs, VEGFR2-activated EPOR caused an interaction between p-EPOR and p-VEGFR2; knockdown of EPOR by siRNA transfection reduced VEGF-induced EC proliferation in association with reduced p-VEGFR2 and p-STAT3; however, inhibition of VEGFR2 activation by siRNA transfection or semaxanib (SU5416) abolished VEGFA-induced proliferation of ECs and phosphorylation of VEGFR2, EPOR, and STAT3. Our results show that VEGFA-induced p-VEGFR2 activates EPOR and causes an interaction between p-EPOR and p-VEGFR2 to enhance VEGFA-induced EC proliferation by exacerbating STAT3 activation, leading to pathological angiogenesis.
