Chlorogenic acid (CGA) is a plant polyphenol with known antioxidant properties. Although some studies suggest that CGA has anticancer properties, others indicate that this dietary constituent may cause DNA damage and induce carcinogenic effects. Because CGA is widely consumed in the form of coffee, it is important to further evaluate the putative DNA-damaging activity of CGA. Here we have emplo...

Chlorogenic acid (CGA) is one of the most abundant polyphenols in the human diet and is suggested to be a potential antiatherosclerotic agent due to its proposed hypolipidemic, anti-inflammatory and antioxidative properties. The aim of this study was to evaluate the effect of CGA on atherosclerosis development in ApoE(-/-) mice and its potential mechanism. ApoE(-/-) mice were fed a cholesterol-...

Chromogranin A (CgA), the major catecholamine storage vesicle (CSV) soluble protein, may index exocytotic sympathoadrenal secretion. To explore CgA in adrenergic tissues, we developed a radioimmunoassay for bovine CgA. Within adrenal medulla CSV, several minor chromogranins had similar amino acid compositions and peptide maps to that of CgA and also showed parallel, partial cross-reactivity in ...

Chromogranin A (CgA) is transported restrictedly to secretory granules in neuroendocrine cells. In addition to pHand Ca2 -dependent aggregation, CgA is known to bind to a number of vesicle matrix proteins. Because the binding-prone property of CgA with secretory proteins may be essential for its targeting to secretory granules, we screened its binding partner proteins using a yeast two-hybrid s...

In cultured cells and isolated perfused organs, catecholamines are coreleased with chromogranin A (CgA) from adrenal chromaffin cells and sympathetic neurons. The corelease suggests that exocytosis is the mechanism of catecholamine secretion. To investigate whether physiologic catecholamine secretion is exocytotic in humans, we measured plasma norepinephrine, epinephrine, and CgA responses to d...

Chlorogenic acid (CGA) has been shown to delay intestinal glucose absorption and inhibit gluconeogenesis. Our aim was to investigate the role of CGA in the regulation of glucose transport in skeletal muscle isolated from db/db mice and L6 skeletal muscle cells. Oral glucose tolerance test was performed on db/db mice treated with CGA and soleus muscle was isolated for 2-deoxyglucose transport st...

PURPOSE The use of replication-selective oncolytic adenoviruses is an emerging therapeutic approach for cancer, which thus far has not been employed for carcinoids. We therefore constructed Ad[CgA-E1A], a novel replication-selective oncolytic adenovirus, where the chromogranin A (CgA) promoter controls expression of the adenoviral E1A gene. EXPERIMENTAL DESIGN The Ad[CgA-E1A] virus was evalua...

Wounding stress is an effective strategy to increase the content of bioactive compounds in horticultural crops. Potato tubers subjected wounding accumulate chlorogenic acid (CGA) and CGA isomers (neo-CGA crypto-CGA), which are phenolics that prevent treat different chronic degenerative diseases. In this study, effects storage temperature (10 °C 20 for 168 h) on accumulation potatoes were evalua...

BACKGROUND To provide quality care to the growing number of older patients, primary care physicians (PCPs) will require support from geriatric specialists. Multidisciplinary comprehensive geriatric assessment (CGA) has been found to improve outcomes in older people. This study explored the contribution of CGA to the management of older patients by their PCPs; PCP attitudes to CGA; and PCP satis...

Chromogranin A (CgA) is transported restrictedly to secretory granules in neuroendocrine cells. In addition to pH-and Ca 2 +-dependent aggregation, CgA is known to bind to a number of vesicle matrix proteins. Because the binding-prone property of CgA with secretory proteins may be essential for its targeting to secretory granules, we screened its binding partner proteins using a yeast two-hybri...
