Endothelial cell caveolar-rafts are considered functional platforms that recruit several pro-angiogenic molecules to realize an efficient angiogenic program. Here we studied the differential caveolar-raft protein composition of endothelial colony-forming cells following stimulation with VEGF, which localizes in caveolae on interaction with its type-2 receptor. Endothelial colony-forming cells a...

Cerebral cavernous malformations (CCMs), one of the most common vascular malformations, are characterized by abnormally dilated intracranial microvascular capillaries resulting in increased susceptibility to hemorrhagic stroke. As an autosomal dominant disorder with incomplete penetrance, majority CCMs gene mutation carriers largely asymptomatic, but, when symptoms occur, disease has typically ...

Angiogenesis is a necessary process for tumor progression and is driven through molecular interactions between cancer cells and neighboring vascular endothelial cells. The primary mediators of angiogenesis are the vascular endothelial growth factors and their respective receptors on endothelial cells. There are several U.S. Food and Drug Administration-approved anti-angiogenic agents in clinica...

Embryonic implantation is a key step in the establishment of pregnancy. In present work, we have carried out an in-depth proteomic analysis secretome (extracellular vesicles and soluble proteins) two bovine blastocysts embryonic trophectoderm primary cultures (BBT), confirming different epithelial–mesenchymal transition stages these cells. BBT-secretomes contain early pregnancy-related proteins...

Tumor derived exosomes are vesicles which contain proteins and microRNAs that mediate cell-cell communication and are involved in angiogenesis and tumor progression. Curcumin derived from the plant Curcuma longa, shows anticancer effects. Exosomes released by CML cells treated with Curcumin contain a high amount of miR-21 that is shuttled into the endothelial cells in a biologically active form...

BACKGROUND Resveratrol increases nitric oxide (NO) production via increased expression and activation of endothelial-form-NO-synthase (eNOS) in endothelial cells. However, the role of downstream cGMP/protein kinase G (PKG) signaling, a pathway activated by NO/eNOS, in pro- and anti-angiogenic effects of resveratrol is still unclear. MATERIALS AND METHODS Endogenous NO/cGMP/PKG pathway and dow...

The process of angiogenesis consists in the sprouting of new blood vessels from existing ones. This is a natural process that occurs in the human body and is essential for organ growth and repair. In the embryonic stage, the blood vessels provide the necessary oxygen, nutrients and instructive trophic signals to promote organ morphogenesis (Coultas et al., 2005). After birth the angiogenic proc...

Shark cartilage is considered as a natural dietary supplement consisting of anti-angiogenic, immunostimulatory, and anti-inflammatory characteristics. Therefore, this study was designed to inspect the possibility that whitecheek shark (Carcharhinus dussumieri) cartilage proteins motivate expression of NKG2D, CXCR3, NKP46, and NKP44 receptors on natural killer cells and their activities against ...

Studies were performed to examine the extent to which mechanical stimuli mediate control of angiogenesis in bladder cells both in vitro and in vivo. Differential gene expression between control nonstretched and cyclically stretched bladder smooth muscle cells was assessed using oligonucleotide microarrays and pathway analysis by the web tool Fast Assignment and Transference of Information (Fati...
