av Integrins in Angiogenesis and Cancer
During angiogenesis, av integrins are overexpressed on the endothelial cell surface to facilitate the growth and survival of newly forming vessels. Accordingly, blockingav integrin function by disrupting ligand binding can produce an antiangiogenic effect. Although the integrin ectodomain regulates ligand binding specificity, the short cytoplasmic tail facilitates intracellular signaling pathwa...
متن کاملFilamin A regulates cell spreading and survival via beta1 integrins.
Cell spreading and exploration of topographically complex substrates require tightly-regulated interactions between extracellular matrix receptors and the cytoskeleton, but the molecular determinants of these interactions are not defined. We examined whether the actin-binding proteins cortactin, vinculin and filamin A are involved in the formation of the earliest extensions of cells spreading o...
متن کاملSignalling via integrins: implications for cell survival and anticancer strategies.
Integrin-associated signalling renders cells more resistant to genotoxic anti-cancer agents like ionizing radiation and chemotherapeutic substances, a phenomenon termed cell adhesion-mediated radioresistance/drug resistance (CAM-RR, CAM-DR). Integrins are heterodimeric cell-surface molecules that on one side link the actin cytoskeleton to the cell membrane and on the other side mediate cell-mat...
متن کاملIntegrins, vascular remodeling, and hypertension.
At the level of the resistance artery, hypertension also brings about a thickening of the vascular wall and inward encroachment on the lumen. This has been reported as being attributable to hypertrophy or hyperplasia of vascular smooth muscle cells (VSMCs), but studies have appeared suggesting that growth is not apparent in arteries at this level of the circulation.1 In addition, detailed struc...
متن کاملIntegrins in vascular development.
Many growth factors and their protein kinase receptors play a role in regulating vascular development. In addition, cell adhesion molecules, such as integrins and their ligands in the extracellular matrix, play important roles in the adhesion, migration, proliferation, survival and differentiation of the cells that form the vasculature. Some integrins are known to be regulated by angiogenic gro...
