AIM OF THE STUDY: The aqueous extract of Terminalia chebular fruits was reported to have anti-hyperglycemia and anti-diabetic complication effects. The present study therefore investigated the protective mechanism of chebulic acid, a phenolcarboxylic acid compound isolated from the ripe fruits of Terminalia chebula against advanced glycation endproducts (AGEs)-induced endothelial cell dysfunction.

Terminalia chebula Retz. has been used in India for a long time to treat many diseases, and its extract was reported to have antidiabetic activity in vivo. In this study, T. chebula methanolic extract (TCE) containing 2.7 % chebulic acid was evaluated for its preventive effects against the formation of advanced glycation end products (AGEs) and endothelial cell dysfunction.

BACKGROUND: Though Mica, a thin and sheet like mineral, has been used as a mineral medicine for treatment of bleeding, dysentery and inflammation in traditional medicine including Ayurveda, the biological evidences of Mica were not clearly elucidated so far. Thus, in the present study, the antitumor mechanism of particled Mica (STB-HO) was examined in colorectal cancers.

Angiogenesis

The medicinal plant Withania somnifera is widely researched for its anti-inflammatory, cardioactive and central nervous system effects. In Ayurveda , the major Traditional Indian medicine system, extracts from W. somnifera are distinctively employed for the treatment of arthritis and menstrual disorders. Because these conditions involve angiogenic processes we hypothesized that the W. somnifera extracts might contain angiogenesis inhibitors. We employed an endothelial cell-sprouting assay to monitor the purification of substances from W.

C-reactive protein (CRP) is a risk marker for cardiovascular events in apparently healthy persons. Cogent data show that, aside from the liver, CRP is produced in atherosclerotic lesions, kidney, neurons, and alveolar macrophages. Because several proatherogenic effects of CRP have been documented in endothelial cells, we examined human aortic endothelial cells (HAEC) for CRP production. We detected the presence of CRP mRNA by RT-PCR and in situ hybridization, intracellular protein by Western blot and secreted protein by ELISA.

OBJECTIVE: Resistin may be associated with obesity and cardiovascular diseases. However, it is unknown whether resistin directly contributes to angiogenesis. In the present study, we evaluated the effects of resistin on angiogenic potential, including endothelial cell proliferation, migration, and capillary-like tube formation. METHODS: Human coronary artery endothelial cells (HCAECs) were treated with resistin. Cell proliferation was evaluated by [3H]thymidine incorporation and MTS assays. Cell migration was assessed by a modified Boyden chamber assay.

Reduced caloric intake decreases arterial blood pressure in healthy individuals and improves endothelium-dependent vasodilation in obese and overweight individuals. The SIRT1 protein deacetylase mediates many of the effects of calorie restriction (CR) on organismal lifespan and metabolic pathways. However, the role of SIRT1 in regulating endothelium-dependent vasomotor tone is not known. Here we show that SIRT1 promotes endothelium-dependent vasodilation by targeting endothelial nitric oxide synthase (eNOS) for deacetylation.

The aim of this article was to examine the protective effect of Chinese traditional medicine Angelica on human umbilical vein endothelial cells (HUVECs, ECV(304)) from injury induced by hyperlipidemic serum (HLS) and to study the underlying mechanisms. Microstructures of HUVECs were observed by a scanning electron microscope. Spectrophotometer and immunocytochemical methods were used to detect the content of NO in the suspension and expression of ICAM-1, TGFbeta(1), bFGF on the cell surface, respectively.

To study the molecular mechanism of action of ligustrazine, a low-density oligonucleotide microarray for cardiovascular disease-related genes, was constructed, and the preparation and hybridization protocols were optimized. Under the optimized conditions, the molecular mechanism of action of ligustrazine was analyzed with human umbilical vein endothelial cells. After 4 h of treatment with 100 microg/ml of ligustrazine, calcium-ATPase gene, sodium channel gene, P450c11 gene in human umbilical vein endothelial cells were up-regulated while apolipoprotein C-III gene was down-regulated.
