Abstract
Exosomes secreted by adipose-derived stem cells (ADSCs) enhance angiogenesis and wound healing. However, in clinical settings, wounds may be infected by various bacteria or pathogens. We investigated whether human ADSCs stimulated with lipopolysaccharide (LPS) secrete exosomes (ADSC-LPS-exo) that augment the angiogenesis of human umbilical vein endothelial cells (HUVECs). ExoQuick-TC exosome precipitation solution was used to purify exosomes from human ADSC culture media in the presence or absence of 1 µg/mL LPS treatment for 24 h. The uptake of ADSC-LPS-exo significantly induced the activation of cAMP response element binding protein (CREB), activating protein 1 (AP-1), and nuclear factor-κB (NF-κB) signaling pathways and increased the migration of and tube formation in HUVECs. RNA interference with CREB, AP-1, or NF-κB1 significantly reduced the migration of and tube formation in HUVECs treated with ADSC-LPS-exo. An experiment with an antibody array for 25 angiogenesis-related proteins revealed that only interleukin-8 expression was significantly upregulated in HUVECs treated with ADSC-LPS-exo. In addition, proteomic analysis revealed that eukaryotic translation initiation factor 4E, amyloid beta A4 protein, integrin beta-1, and ras-related C3 botulinum toxin substrate 1 may be potential candidates involved in ADSC-LPS-exo-mediated enhanced angiogenesis.

Abstract
Objective To investigate the effects of mechanical strain on Ca2+-calmodulin dependent kinase (CaMK)-cAMP response element binding protein (CREB) signal pathway and proliferation of osteoblasts.Methods Using a four-point bending device, MC3T3-E1 cells were exposed to mechanical tensile strains of 2500 µs and 5000 µs at 0.5 Hz respectively. The intracellular free Ca2+ ([Ca2+]i) concentration and calmodulin activity were assayed by fluorospectrophotometry, CaMK II β, CREB, and phosphorylated (activated) CREB (p-CREB) were assessed by Western blot, and cells proliferation was assayed with MTT. Pretreatment with verapamil was carried out to block Ca2+ channel, and inhibitor U73122 was used to inhibit phospholipase C (PLC).Results Mechanical strains of 2500 µs and 5000 µs for 1 to 10 minutes both increased [Ca2+]i level of the cells. The 2500 µs strain, a periodicity of 1 h/d for 3 days, activated calmodulin, elevated protein levels of CaMK II β and p-CREB, and promoted cells proliferation, which were attenuated by pretreatment of verapamil or U73122. The effects of 5000 µs strain on calmodulin, CaMK II β, p-CREB and proliferation were contrary to 2500 µs strain.Conclusion The mechanical strain regulates osteoblasts proliferation through Ca2+-CaMK-CREB signal pathway via Ca2+ channel and PLC/IP3 transduction cascades.

Abstract
BACKGROUND Sodium formononetin-3'-sulphonate (Sul-F) is a derivative of the isoflavone formononetin. In this study, we investigated whether Sul-F can regulate angiogenesis and the potential mechanism in vitro. METHODS We examined the effects of Sul-F on cell proliferation, cell invasion, and tube formation in the human umbilical vein endothelial cell line (HUVEC). To better understand the mechanism involved, we investigated effects of the following compounds: cAMP response element-binding protein (CREB) inhibitor 2-naphthol-AS-E-phosphate (KG-501), early growth response 3 (Egr-3) siRNA, vascular endothelial growth factor (VEGF) antagonist soluble VEGF receptor 1 (sFlt-1), VEGF receptor 2 blocker SU-1498, Wnt5a antagonist WIF-1 recombinant protein (WIF-1), and inhibitor of Wnt/β-catenin recombinant Dickkopf-1 protein (DKK-1). HUVEC proliferation was tested by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT). A scratch adhesion test was used to assess cell invasion ability. Matrigel tube formation assay was performed to test capillary tube formation ability. Activation of the VEGF/CREB/Egr-3/Vascular cell adhesion molecule 1 (VCAM-1) pathway in HUVEC was tested by Western blot analysis. RESULTS Our results suggest that Sul-F induced angiogenesis in vitro by enhancing cell proliferation, invasion, and tube formation. The increase in proliferation and tube formation by Sul-F was counteracted by DKK-1, WIF-1, SU1498, KG-501, sFlt-1, and Egr-3 siRNA. CONCLUSIONS These results may suggest that Sul-F induces angiogenesis in vitro via a programed Wnt/β-catenin pathway and VEGF/CREB/Egr-3/VCAM-1 signaling axis.

Abstract
Curculigoside A has shown protective effects against rat cortical neuron damage in vivo. However, the molecular mechanisms through which Curculigoside A affords this protection are unclear. In the present study, we sought to elucidate the mechanisms of angiogenesis in rat aortic endothelial cells (RAEC), rat aortic smooth muscle cells (RASMC) as well as a rat model of cerebral ischemia and reperfusion injury following treatment with Curculigoside A. We examined the role of Curculigoside A on RAEC and RASMC proliferation, migration, and tube formation in vitro and in a cerebral ischemia and reperfusion injury rat model. We used the recombinant Dickkopf (DKK)-1 protein, a Wnt/β-catenin inhibitor, and the recombinant WIF-1 protein, a Wnt5a antagonist to determine mechanisms. In addition, we measured leakage of the blood-brain barrier (BBB) and tested for angiogenesis associated proteins. Our data suggest that Curculigoside A induces angiogenesis in vitro by increasing proliferation, migration and tube formation in RAEC and RASMC. The increase in Curculigoside A-induced proliferation and tube formation was counteracted by DKK-1 and WIF-1. Curculigoside A increased expression of VEGF, p-VEGFR, p-CREB, Egr-3, VCAM-1, Ang1 and Tie2 while prohibiting BBB leakage in cerebral ischemia and reperfusion injured rats. However, Cyclosporine A, a CREB inhibitor, reduced the expression of p-CREB, Egr-3, VCAM-1, Ang1 and Tie2. These data suggest that Curculigoside A induces cell proliferation and angiogenesis through the Wnt5a/β-catenin and VEGF/CREB/Egr-3/VCAM-1 signaling axis and promotes maturation and stability of new blood vessels via increasing Ang1 and Tie-2 expression.

CREB-binding protein silencing inhibits thrombin-induced endothelial progenitor cells angiogenesis. Mol Biol Rep 2011; 39:2773-9.

Abstract
Endothelial progenitor cells (EPCs) are known to promote neovascularization in ischemic diseases. Recent evidence from our group suggested that CREB-binding protein (CBP) plays an important role in thrombin-induced EPCs migration. However, whether CBP could regulate EPCs angiogenic properties is unknown. In the present study, we investigated whether CBP silencing could inhibit thrombin-induced EPCs angiogenesis. EPCs isolated from the bone marrow of Sprague-Dawley rats were cultured and identified, and then were treated by thrombin alone or combined with CBP-shRNA lentivirus. The effect of CBP silencing on EPCs proliferation was assessed using BrdU incorporation assay. Cell adhesion and tube formation were detected to evaluate the angiogenic functions. Finally, mRNA and protein expression of relevant angiogenic genes were examined by real-time PCR, western-blot, and enzyme-linked immunoassay respectively. Luciferase reporter gene assay was performed to evaluate NF-κB activity. Administration of thrombin significantly promoted EPCs proliferation and adhesion. Thrombin also increased the tube formation in Matrigel assay. However, these effects of thrombin were abolished by CBP gene silencing. CBP silencing also abrogated thrombin-induced increases of integrin β2 expression. In thrombin-induced EPCs, CBP silencing significantly decreased the secretion of VEGF, IL-6 and suppressed NF-κB activity. In conclusion, thrombin-induced EPCs proliferation, adhesion, and tube formation were inhibited by CBP silencing, indicating that CBP plays an important role in thrombin-induced EPCs neovascularization.
