AIMS Ginsenoside-Rg1, the most prevalent active constituent of Panax ginseng, has been shown to possess potent pro-angiogenic properties and therefore poses special interest for the development as a novel modality for angiotherapy. Rg1 can activate the glucocorticoid receptor (GR). However, the mechanism that transmits these pro-angiogenic effects is still unclear. METHODS AND RESULTS By usin...
Plant flavonoid apigenin prevents and inhibits UVB-induced carcinogenesis in the skin and has strong anti-proliferative and anti-angiogenic properties. Here we identify mechanisms, by which apigenin controls these oncogenic events. We show that apigenin acts, at least in part, via endogenous angiogenesis inhibitor, thrombospondin-1 (TSP1). TSP1 expression by the epidermal keratinocytes is poten...
macrophages accumulate in poorly vascularised and hypoxic sites including solid tumours, wounds and sites of infection and inflammation where they can be exposed to low levels of oxygen for long periods. up to date, different studies have shown that a number of transcription factors are activated by hypoxia which in turn activate a broad array of mitogenic, pro-invasive, pro-angiogenic, and pro...
This study aimed to assess the potential anti-angiogenic mechanism of Phyllanthus urinaria (P. urinaria) and characterize the major compound in P. urinaria that exerts anti-angiogenic effect. The water extract of P. urinaria and Ellagic Acid were used to evaluate the anti-angiogenic effect in chorioallantoic membrane (CAM) in chicken embryo and human vascular endothelial cells (HUVECs). The ma...
OBJECTIVE Recent studies have shown that altered mitochondrial dynamics impairs the function in senescent endothelial cells (ECs). However, the underlying molecular mechanism remains to be elucidated. Herein, we investigated the role and underlying mechanism of mitochondrial fission protein dynamin-related protein 1 (DRP1) in vascular aging. APPROACH AND RESULTS We found that DRP1 expression ...
The discovery of bone marrow-derived endothelial progenitors in the peripheral blood has promoted intensive studies on the potential of cell therapy for various human diseases. Accumulating evidence has suggested that implantation of bone marrow mononuclear cells effectively promotes neovascularization in ischemic tissues. It has also been reported that the implanted cells are incorporated not ...
Background: Galectin, an animal lectin that recognizes b-galactosides of glycoconjugates, is involved in multiple biological functions such as cell growth, differentiation, apoptosis, signal transduction and angiogenesis. Overexpression of galectin-3 was observed in different tumors which was related to pro-angiogenic activity. In addition, galectin-3 is intensely expressed in corpus luteum (CL...
Cerebral cavernous malformations (CCMs), one of the most common vascular malformations, are characterized by abnormally dilated intracranial microvascular capillaries resulting in increased susceptibility to hemorrhagic stroke. As an autosomal dominant disorder with incomplete penetrance, majority CCMs gene mutation carriers largely asymptomatic, but, when symptoms occur, disease has typically ...
Huang Qin (root of Scutellaria baicalensis) is a widely used herb in different countries for adjuvant therapy of inflammation, diabetes, hypertension, different kinds of cancer and virus related diseases. Baicalin is the main flavonoid in this herb and has been extensively studied for 30 years. The angiogenic effect of herb Huang Qin extract and baicalin was found 13 years ago, however, the res...
