Sprouting of new capillaries from pre-existing blood vessels is a hallmark of angiogenesis during embryonic development and solid tumor growth [1]. In addition to the vascular endothelial growth factor (VEGF) and its receptors, the Tie receptors and their newly identified ligands, the angiopoietins, have been implicated in the control of blood vessel formation [2,3]. Although 'knockouts' of the...
Hypertension is a very common but incompletely understood disease, especially in its pathogenesis and vascular complications occurring in the cardiovascular research filed. There are many explanations for pathological mechanisms in hypertension, including adrenergic over-reactivity, renin-angiotensin-aldosteron system abnormality and constitutionalgenetic-environmental factors. Recently emergin...
BACKGROUND Angiopoietin (Ang) -1 and -2, their receptor Tie-2, and vascular endothelial growth factor (VEGF) regulate angiogenesis and may be important in myocardial collateral development. Elevated levels of growth factors and their receptors are reported in myocardial infarction (MI), but changes after an acute coronary event are unknown. METHODS AND RESULTS Plasma Ang-1, Ang-2, Tie-2, and ...
Hepatocellular carcinoma (HCC) is a hypervascular malignancy and is the third leading cause of death worldwide. The disease has multiple predisposing risk factors and limited treatment options. Although the precise mechanism(s) underlying HCC is unknown, several pathways have been implicated in its development. HCC is a vascular tumor and angiogenesis is believed to play an important role in it...
Recent evidence suggests that loss of endothelial barrier function and resulting microvascular leak play important mechanistic roles in the pathogenesis of infection-related end-organ dysfunction and failure. Several distinct therapeutic strategies, designed to prevent or limit infection-related microvascular endothelial activation and permeability, thereby mitigating end-organ injury/dysfuncti...
