Metanephrine and normetanephrine (collectively referred to as metanephrines) are the 3-methoxy metabolites of epinephrine and norepinephrine, respectively. The metanephrines are stable metabolites and are cosecreted directly with catecholamines by pheochromocytomas and other neural crest tumors. This results in sustained elevations in plasma ...Chromogranin A, due to its primary expression throughout the neuroendocrine system, is a widely accepted biomarker for the assessment of neuro-endocrine tumors. It has been traditionally used in the management of patients with tumors of gastro-enteropancreatic origin. Lately, it has also been implicated in various conditions …

The goal has been to draw the main lines of progress in the chromogranin field, from the early discoveries towards our current understanding of the functional implications. It is evident from the accumulated literature that an unforseen diversity of cellular processes involve chromogranins.Chromogranin A (CgA) is a protein released by neuroendocrine cells. Neuroendocrine cells are found in many organs in the body and have characteristics of both nerve cells and cells that make hormones. A test for chromogranin A measures the amount of CgA in the blood. This is known as a tumor marker test because CgA can be released in higher ...This report focuses on Chromogranin A (CGA) and some of its derived peptides in critically ill patients, with attention paid to their potential to become biomarkers of severity and actors of defense. First, we studied whether circulating CGA may be a biomarker of outcome in non-selected critically ill patients: CGA concentrations were …Background: Neuroendocrine tumors (NETs) are a form of cancer that differ from other neoplasia in that they synthesize, store, and secrete peptides, e.g., chromogranin A (CgA) and amines. A critical issue is late diagnosis due to failure to identify symptoms or to establish the biochemical diagnosis. We review here the utility of CgA measurement in NETs and describe its biological role and the ...

Limitations. With reduced renal blood flow, creatinine rises less quickly than urea nitrogen. Concentration of creatinine only becomes abnormal when about half or more of the nephrons have stopped functioning in chronic progressive renal disease. Antibiotics containing cephalosporin lead to significant false-positive values if samples are drawn ...

Here, we further examined the influence of other lumenal proteins on fusion pore expansion, especially chromogranin A (CgA), the major and ubiquitous lumenal protein in chromaffin granules. Polarized TIRF microscopy demonstrated that the fusion pore curvature of granules containing CgA-EGFP was long lived, with curvature lifetimes comparable to ...

Chromogranin A (CGA) is a 439-amino acid protein with a molecular weight of 48 to 60 kDa, depending on glycosylation and phosphorylation status. It is a member of the granin family of proteins and polypeptides. Granins are widespread in endocrine, neuroendocrine, peripheral, and central nervous tissues, where they are found in secretory ...Chromogranin A (CgA) is a common marker for enteroendocrine cells in the gut, and CgA-immunoreactive cell densities are abnormal in patients with irritable bowel syndrome (IBS). The majority of patients with IBS report that their symptoms develop after consuming certain foodstuffs. In the present study, we investigated the effects of dietary ...Nonhormonal secretory products, such as chromogranin A, pancreastatin, and pancreatic polypeptide are often produced by both functional and nonfunctional NETs, and can serve as circulating serum tumor markers . In addition to these hormonal and nonhormonal peptide markers, novel circulating RNA-based tests have been developed that are ... כרומוגרנין A (להלן CgA) הוא חלבון הפרשתי המורכב מ-439 חומצות אמיניות, במשקל מולקולארי של 48 עד 60 אלף דלטון, בהתאם לדרגת הגליקוזילציה והזרחון שלו. CgA נמצא בריכוז גבוה בבועיות גדולות הממוקמות בתאים ... Chromogranin A (CgA) is a protein present in neuroendocrine vesicles. Small cell lung cancer (SCLC) is considered a neuroendocrine tumour. It is possible to demonstrate CgA expression in SCLC by immunohistochemical methods. Since CgA is released to the circulation it might also work as a clinical tumour marker.
