Vascular endothelial growth factor-A signaling in bone marrow-derived endothelial progenitor cells exposed to hypoxic stress.
Bone marrow-derived endothelial progenitor cells (BM-EPCs) are stimulated by vascular endothelial growth factor-A (VEGF-A) and other potent proangiogenic factors. During angiogenesis, an increase in VEGF-A expression stimulates BM-EPCs to enhance endothelial tube formation and contribute to an increase in microvessel density. Hypoxia is known to produce an enhanced angiogenic response and heigh...
متن کاملDifferential effects of hypoxic stress in alveolar epithelial cells and microvascular endothelial cells.
Under hypoxic conditions eukaryotic cells and tissues undergo adaptive responses involving glycolysis, angiogenesis, vasoconstriction and inflammation. The underlying molecular mechanisms are not yet fully elucidated and are most likely cell and tissue specific. In the lung, alveolar epithelial cells and microvascular endothelial cells are highly sensitive to hypoxia and together orchestrate a ...
متن کاملIdentification of protein disulfide isomerase as an endothelial hypoxic stress protein.
Endothelial cells (EC) exposed to hypoxia upregulate a unique set of five stress proteins. These proteins are upregulated in human and bovine aortic and pulmonary artery EC and are distinct from heat shock or glucose-regulated proteins. We previously identified two of these proteins as the glycolytic enzymes glyceraldehyde-3-phosphate dehydrogenase and enolase and postulated that the remaining ...
متن کاملPR39 Inhibits Apoptosis in Hypoxic Endothelial Cells
Background—PR39 is a prolineand arginine-rich peptide implicated in wound healing and myocardial ischemia protection. To determine the potential mechanisms of PR39 in ischemia, we examined the role of PR39 in hypoxia-induced apoptosis in vascular endothelial cells. Methods and Results—Hypoxia results in an increase of apoptosis in bovine aortic endothelial cells (BAECs), as determined by termin...
متن کاملCD105 prevents apoptosis in hypoxic endothelial cells.
CD105, a marker of endothelial cells, is abundantly expressed in tissues undergoing angiogenesis and is a receptor for transforming growth factorbeta. The pivotal role of CD105 in the vascular system was demonstrated by the severe vascular defects that occur in CD105-knockout mice, but the exact mechanisms for CD105 regulation of vascular development have not been fully elucidated. In light of ...
