The Release of Nitric Oxide from S-Nitrosothiols Promotes Angiogenesis
BACKGROUND Free nitric oxide (NO) reacts with sulphydryl residues to form S-nitrosothiols, which act as NO reservoirs. We sought to determine whether thiol-preserving agents and antioxidants, such as dithiothreitol (DTT) and vitamin C, induce NO release from S-nitrosylated proteins in endothelial cell cultures to promote angiogenesis. METHODOLOGY/PRINCIPAL FINDINGS NO release was measured dir...
متن کاملControlled release of nitric oxide chemotherapy using a nano- sized biodegradable multi-arm polymer
Nitric oxide is a cell signaling molecule that can be a potent inducer of cell death in cancers at elevated concentrations. Nitric oxide molecules are short-lived in vivo; therefore, NO-donating prodrugs have been developed that can deliver NO to tissues at micromolar concentrations. However, NO is also toxic to normal tissues and chronic exposure at low levels can induce tumor growth. We have ...
متن کاملNitric oxide and angiogenesis.
Endothelium-derived nitric oxide (NO) is a mediator of angiogenesis. Vascular endothelial growth factor (VEGF) stimulates the release of NO from cultured human umbilical venous endothelial cells and upregulates the expression of nitric oxide synthase (NOS).1,2 Segments of rabbit thoracic aorta release NO in response to VEGF; preincubation with L-arginine increases basal and VEGFstimulated NO re...
متن کاملBiodegradable and Biocompatible Systems Based on Hydroxyapatite Nanoparticles
Composites of hydroxyapatite (HAp) are widely employed in biomedical applications due to their biocompatibility, bioactivity and osteoconductivity properties. In fact, the development of industrially scalable hybrids at low cost and high efficiency has a great impact, for example, on bone tissue engineering applications and even as drug delivery systems. New nanocomposites constituted by HAp na...
متن کاملNitric Oxide Mediates Angiogenesis
We evaluated the effects of nitric oxide (NO) generators and endogenous production of NO elicited by substance P (SP) in the angiogenesis process. Angiogenesis was monitored in the rabbit cornea in vivo and in vitro by measuring the growth and migration of endothelial cells isolated from coronary postcapillary venules. The angiogenesis promoted in the rabbit cornea by [Sari]-SP-sulfone, a stabl...
