We aimed to investigate the correlation between the levels of circulating miR-214 and the expression of vascular endothelial growth factor (VEGF) in the pathogenesis of coronary heart disease patients to further explore the mechanism involved in the vasculogenesis.
Because hypoxia-inducible factor (HIF)-1alpha is a transcriptional activator of vascular endothelial growth factor (VEGF) and is critical for initiating angiogenic responses to hypoxia, we investigated the expression of HIF-1alpha and VEGF in specimens of human heart tissue to elucidate the molecular responses to myocardial ischemia in diabetic patients during unstable angina.
Vascular endothelial growth factor (VEGF) is an important active protein for the induction of angiogenesis and improvement in cardiac function after myocardial ischemia; however, the lack of a delivery system targeted to the injured myocardium reduces the local therapeutic efficacy of VEGF and increases its possible adverse effects.
Thymosin beta-4 (TB4) and vascular endothelial growth factor (VEGF) are linked to adult epicardial progenitor cell mobilization and neovascularization and is cardioprotective after myocardial ischemia.
Several clinical trials based on intramyocardial injection of VEGF DNA in patients with otherwise inoperable coronary artery disease and intractable angina pectoris have recently been completed.
This report summarizes a phase I clinical experience with a gene-therapy strategy that used an E1(-)E3(-) adenovirus (Ad) gene-transfer vector expressing human vascular endothelial growth factor (VEGF) 121 cDNA (Ad(GV)VEGF121.10) to induce therapeutic angiogenesis in the myocardium of individuals with clinically significant coronary artery disease.
Currently, about 200 patients have been treated with intramyocardial VEGF gene therapy for peripheral occlusive artery disease or for myocardial ischemia.
The central role of vascular endothelial growth factor (VEGF) in angiogenesis in health and disease makes it attractive both as a therapeutic target for anti-angiogenic drugs and as a pro-angiogenic cytokine for the treatment of ischaemic heart disease.
Recent experiments performed in this same porcine model of myocardial ischemia have shown that direct intramyocardial gene transfer of naked plasmid DNA encoding VEGF (phVEGF(165), the identical plasmid used in our previous animal and human clinical trials) can be safely and successfully achieved through a minimally invasive chest wall incision.
In this brief review, the role of a prime angiogenic candidate, namely vascular endothelial growth factor (VEGF) and its homologues, in physiological and pathological angiogenesis will be discussed with particular attention to myocardial ischemia and heart failure.
Epicardial fat was clearly different from substernal fat because there was a far higher expression of haptoglobin, prostaglandin D(2) synthase, nerve growth factor beta, the soluble vascular endothelial growth factor receptor (FLT1), and alpha1 glycoprotein but not of inflammatory adipokines such as monocyte chemoattractant protein-1, interleukin (IL)-8, IL-1beta, tumor necrosis factor alpha, serum amyloid A, plasminogen activator inhibitor-1, or adiponectin despite underlying coronary atherosclerosis.
Vascular endothelial growth factor (VEGF) and its receptor KDR (kinase insert domain-containing receptor/fetal liver kinase-1, also called VEGFR2) play critical roles in angiogenesis and vascular repair, which are involved in the progress of coronary heart disease.
