A protein required for the activation of the lac operon has been extensively purified and partly characterized. This protein, called CGA protein (catabolite gene activator protein, sometimes named CAP), is a dimer with subunits of 22,000 daltons. Purified CGA protein has a substantial affinity for DNA; this affinity is greatly strengthened by cAMP and strongly inhibited by cGMP. Other studies h...

BACKGROUND Nursing homes are important locations for palliative care. Through comprehensive geriatric assessments (CGAs), evaluations can be made of palliative care needs of nursing home residents. The interRAI Palliative Care instrument (interRAI PC) is a CGA that evaluates diverse palliative care needs of adults in all healthcare settings. The evaluation results in Client Assessment Protocols...

Chromogranin polypeptides of Mr 100,000, Mr 85,000, Mr 75,000, and Mr 65,000 have been detected in adrenal medulla chromaffin granules using anti-chromogranin antiserum. Monoclonal antibodies to this protein also detect the multiple molecular weight chromogranin polypeptides. Analysis of phosphorylated amino acids gives a value of 5 phosphoserine residues/mol of Mr 75,000 chromogranin polypepti...

Chromogranins A and B and secretogranin II are a family of acidic proteins found in neuroendocrine secretory vesicles; these proteins contain multiple potential cleavage sites for proteolytic processing by the mammalian subtilisin-like serine endoproteases PC1 and PC2 (prohormone convertases 1 and 2), and furin. We explored the role of these endoproteases in chromogranin processing in AtT-20 mo...

Chromogranins A and B, two widespread neuroendocrine secretory proteins, contain a homologous N-terminal disulfide-bonded loop that is required for sorting to secretory granules. Here we have investigated the role of this loop in the oligomerization of chromogranin A. Reduction of the disulfide bond or the addition of an excess of an N-terminal chromogranin A fragment containing the loop (CgA1-...

Since the initial demonstration of increased circulating norepinephrine in patients with chronic heart failure, a large number of investigations on neuroendocrine activation in heart failure have followed. It is now clear that persistent activation of neuroendocrine systems, notably the adrenergic system and the renin–angiotensin system is maladaptive in heart failure (reviewed in). In this iss...

Chromaffin granule transmitters such as chromogranin A and catecholamines have been used in the diagnosis of pheochromocytoma, but the diagnostic and prognostic value of chromogranin A have not been explored in malignant pheochromocytoma. We evaluated these transmitters in patients with pheochromocytoma (n=27), both benign (n=13) and malignant (n=14). Patients with benign pheochromocytoma were ...
